Difference between public security and private security

In this article, we will be very clear that both public and private security are essential in a country. They do not contrast, on the contrary, they complement each other. It is very important in these two areas, the preparation of the professional to ensure the safety and protection of citizens.

Public safety and private security: essential

The current society increasingly dynamic, changing and complicated requires more and more new police services and new security solutions, so if there is something clear is that there is demand for everyone.

But if we should be clear about something, public safety and private security are not mutually exclusive, but together they add up.

Private security cannot enter areas of public security, nor is it in areas of private security.

Functions of public security

Personal freedom, free movement, fundamental rights, compliance with standards, are functions that, due to their public nature, must be exercised exclusively by security forces and bodies, although within these there is a distribution of competences and matters, without this supposing a reduction to the principle of reciprocal collaboration between all the police bodies dependent on the different public administrations.

Combining still more, each police body has its own structures to take charge of the different matters that must be addressed, gender and family violence, drug trafficking, environment, etc., since it is necessary more and more of a more specialized training to address the different types of crime that arise.

Private security functions

The private security on the other hand must address other framed needs within the private sector, ie activities that cannot be entrusted to public safety, because pose a need for someone who is entitled to secure their assets, property, businesses etc. with the hiring of private security services, but whose cost cannot be borne by the public administration, which would be the same as for all citizens. Exception to this case would be when the administration is the one that contracts private services for the surveillance of public buildings, in these cases what is intended is not to subtract from the citizen security police officers for functions that private security personnel can exercise with full guarantees.

But when we talk about private security we do not only refer to the security guards, perhaps the most visible face of the sector, but to the escorts, field guards and fishermen, security chiefs, security directors, and all the personnel systems installer. security, operators of alarm receiving stations and also private detectives, so that the range of skills in this sector is sufficiently broad, necessary and that they do not interfere in the areas of public safety, but are necessary partners.

Public and private security

We cannot enter into conflicts that do not lead anywhere, among them security must be exercised only by police agents and not by private security personnel, but we must encourage that both have the means and resources necessary for an effective and professional work, providing quality continuous training.

It is clear that there is demand for all, that competencies are not invaded since all the cases in which private security intervenes are reflected in the regulations and in addition it is subordinated to public security, and that specialization is a determining factor in all security areas.

Functions and skills of a security engineer

Security engineers work in a wide range of industries such as manufacturing and insurance. They supervise and train staff at workplaces, ensuring that people are safe from injury. Depending on the organization, a security engineer is also called a security manager, security coordinator or security director. Candidates with a bachelor’s degree in engineering and a specialization in occupational health and safety are eligible for jobs in safety engineering.

Knowledge requirements

Security engineers must know the equipment, its operations, as well as security issues and measures to ensure the protection of the people who work with them. They should also be familiar with the different methods used in the development of safety training curricula and the training of people to adopt these safety measures. Safety engineers must be well informed about government regulations and company regulations regarding the safe operation of equipment and accidents.


To accomplish their work effectively, security engineers must have excellent oral and written communication skills, with a strong ability to instruct, negotiate and convince people. They should also be able to have good relationships and motivate others to follow established procedures for their own safety. They should also be good listeners, paying attention to the opinions of workers to understand the practical problems they face during their work. Security engineers also require critical and creative thinking skills to assess security aspects and develop alternative solutions tailored to the situation of an organization.


Security engineers have to undergo mandatory training to obtain certification from the Occupational Safety and Health Association. Using this knowledge, they work to ensure that an organization complies with all regulations, such as the installation of safety devices and the training of personnel in safe operating procedures. Security engineers develop security programs and risk control measures according to OSHA standards and prepare manuals to document this. In addition, they work in conjunction with the administration to implement training programs in safety practices for operators when they work in plants, construction sites or transportation systems.

Training functions

One of the main functions of a safety engineer is to evaluate the equipment and processes to find potentially hazardous areas. This evaluation is possible through the study of incidents that have occurred, such as fires, diseases or chemical toxicity associated with the use of equipment or a particular process. Through periodic inspections and observations of work processes such as those made by operators, safety engineers identify defects that have the potential to cause damage or injury. In some cases, it may be necessary to evaluate some new design that is being developed to ensure that there is no danger

How much can I earn if I work while I’m in social security

Depending on the amount of money you earn in your career, you may be able to afford to live off your monthly Social Security check. However, if you did not earn high wages before your retirement, you may have to get a job to supplement your Social Security income. Factors such as age and when you showed up to collect Social Security retirement benefits are reflected in the amount of money you can earn while working part-time or full-time.

Work credits

Before collecting retirement benefits from Social Security, you must earn a sufficient salary. Depending on the amount of gross wages you receive, the Social Security Administration gives you a work credit. In April 2011, to receive Social Security retirement benefits, you had to earn at least four work credits a year. The Social Security Administration records a work credit after you earn $ 1,200 in gross wages for one year. The maximum number of credits you can win in a year is four.

Year of full retirement

After reaching the year of your full retirement age, you can earn up to $ 37,680 in annual wages before the Social Security Administration deducts money from your monthly retirement check. Your full retirement age depends on the year you were born. For example, if you were born in 1937 or earlier, your full retirement age is at 65. If you were born between 1943 and 1954, your full retirement age is 66. If you were born in 1960 or later, you will reach retirement age at 67.

Full retirement age

Once you reach full retirement age, you will no longer have to report your wages to the Social Security Administration. You can also earn as much as you want while you work part time and / or full time and receive all your retirement benefits. If you wait until you reach full retirement age to receive Social Security retirement benefits, the amount of monthly benefits you will receive will not increase.

How to create a security manual

According to HSE Health and Safety, “Managing health and safety is a little different than managing any other aspect of your business, you have to do a risk assessment, to get information about the risks in your workplace and put in marches reasonable measures to control them.” To manage these risk factors and protect employees, each organization must prepare a complete safety manual. The safety of employees is of utmost importance for a company and for its proper functioning. An appropriate safety manual will create a healthy environment for both the employer and employees.

Examine the risks for workers with the descriptions of the different positions. The risks for secondary operators are different from those of employees who come into direct contact with hazardous material. For example, employees who manufacture a certain product face different risks than those who pack the product.

Check all areas prone to accidents, such as slippery areas, broken roofs, parking space and hallways. These areas can be unsafe if they are not examined; The necessary repairs should be made as soon as possible.

It collects information for the protection and safety of personnel. The first aid procedure must be readily available to all employees. Personnel should always follow basic safety instructions, such as washing body parts exposed to chemicals in hazardous areas. Also, specify the safety equipment such as glasses and gloves when required.

Organize the information into several sections so that employees understand it easily. It includes the procedures to follow in case of machinery failure. For example, if the machinery is not working properly, employees should immediately inform the employer and call the mechanics.

Make sure there is a procedure for the proper disposal of waste created by your company, as it can be dangerous to the health of your employees.

Develop a written plan to avoid accidents. Teach employees to respond to an emergency situation such as an accident or setback. Make your employees know where the alarms, emergency exits and first aid kits are. Includes safety standards for manufacturers that assemble machinery to protect employees.

Indicates the procedure to follow in the event of an employee’s accident and disciplinary measures. It includes an emergency exit plan in the safety manual and instructions on how to respond to an emergency situation, such as calling an ambulance or informing the employer.

Provide copies of the insurance forms in the safety manual. Make sure your employees know about insurance policies in case of accidents.

Put your manual in a folder with three rings. It is good to do this since the necessary changes can easily be added or omitted. You can use separators so your employees can easily find the policies they want to read. The security manual should also be available online for easy access.


Ask employees about the potential hazards they face individually.


For large companies, a safety manual should be developed and created by an experienced team of health professionals, industrial hygienists and attorneys, to provide an economic method in accordance with Occupational Safety and Health (OSHA) regulations and regulations. .

Tips for driving in winter with safety

Snow, ice, rain and fog are just some of the inclement weather during the winter season. It is necessary to take into account a series of tips to maintain road safety also in winter. Why is it so important to pay attention to how to drive in winter?

Check the status of your vehicle

Before starting to drive, you have to check the condition of the vehicle. Take it to a workshop to make sure everything is in order and there is no risk to safety. Check the level of all the liquids in the car and, above all, the antifreeze. Brakes and steering must work 100%. No less important are the windshield wipers to ensure visibility even with any type of rain, snow or the “spray” effect of the vehicles that circulate in front of us. Also check that the heating and that the windows are playing correctly.

Change the tires or take the chains

If you are going to drive on mountain roads or very cold areas it is recommended to change the tires for winter ones.

If you do not decide to change the tires the snow chains should be present in your trunk, always. A cold wave can bring snow or ice to any corner and we must be prepared for it. The disadvantage of snow chains is their installation. It is necessary to know how to install them before leaving.

Do you have everything you need?

Before leaving you have to check that we carry the emergency triangle, the reflective vest…. It is also useful to carry a small snow shovel, in case we get stuck, gloves and a blanket. The deposit is full, is another of the tips. If the car is immobilized on the road by heavy snow, it is convenient that you can keep the heating on.

Lights, tuning

In times of poor visibility such as winter, it is advisable to use lights during the day. Check the correct operation of all lights, both front and rear. It is the period with the fewest hours of light, so it is very important to see and be seen, to drive in winter safely. A good regulation of the lights will allow us, not to dazzle the other drivers, and at the same time take better advantage of the light beam of our bulbs.

If snow is expected, stay home

The best recommendation for driving safely in the winter is to be farsighted and not drive in those circumstances. If it is not possible and we have to face the road, it is convenient to know that:

When the thermometers mark zero or less, the road may be icy. Shady areas are very dangerous because they can have ice sheets. The first hours of the day are the most likely. Keep in mind that so that the car does not slip or skid, moderation and low speed will be your allies. Softness with the steering wheel and the accelerator and use the brake as little as possible.

It is common that with the contrast of heat from the interior of the car with the cold of the outside the crystals are fogged. It is necessary to eliminate the steam from the windows with the car’s air conditioning system.

When you park in an area with very low temperatures, you have to lift the windshield wipers to prevent them from breaking with snow or ice. Also keep in mind that brake pads can freeze and stick to the disc.

If despite all these recommendations to drive safely in winter, your car is stuck or immobilized by a large snowfall, it is advisable to leave freeway to the snowplows and not leave the vehicle without knowing a place to take refuge.

How to wire the cables for a security camera

Security cameras need two types of cables to operate, a power cable and a video cable. Wireless security cameras do not require a video cable but a power cable. The power cable carries 12 volts in direct current, low voltage power from the transformer, which is connected to an output of 110 volts of alternating current, to the camera. This cable has two 18 gauge wires, one positive and one negative, both inside the same sheath. The negative cable is marked with a white or black stripe. The video cable is of type RG-59: coaxial cable that is shielded and requires BNC type connectors to protect the integrity of the video signal that is transmitted.


Power cord

  1. Use your knife or cable cutter to separate the two insulated wires from each other approximately three inches (7.6 cm) from the cut end of the cable, leaving the insulation intact on both cables. Usually you can manually separate the cables. Do this at the two ends you want to splice. Now you should have two power cords, each with two insulated wires coming out of each which in total gives four wires to splice.
  2. Remove half an inch of insulation (1.20 cm) from each end of the four wires.
  3. Splice both power cords, using the wire nuts, twisting the exposed copper ends together making sure that you twist the positive wire from one wire to the positive wire from the other wire and the negative wire, or wire from one wire to the negative wire from the other wire cable. Screw a wire nut onto the positive threaded wires and a second wire nut for the negative threaded wires. Place the wire nuts against the wire and wrap everything with electrical tape.
  4. Splice both power cables, using the butt connectors, preparing the wires just as it was done with the splice of the wire nuts, only without screwing them. Insert the exposed positive copper wire into one end of the butt connector and crimp that end of the connector. Insert the other positive wire on the other end of the same stop connector and grease it. Do the same for the two negative wires using the second stop connector. Wrap everything with electrician’s electrical tape.

Video cable

  1. Look at the end of the RG-59 type cable and you’ll see four separate parts that make up the cable. In the center is the copper conductor cable. Surrounding the central conductor wire is a white polyurethane insulation. Next is the aluminum or copper braid. And finally, there is the external cover of the cable. As you prepare this cable for BNC type connectors it is important that you prepare each of these four separate parts independently of each one. The central copper conductor should be kept separate from the braid.
  2. Take the crimping tube from the BNC type connectors and hold it next to the end of the RG-59 type cable to measure your first cut. The crimping tube will have one part with a large diameter and another with a smaller diameter. The part with the largest diameter is the part of the crimping tube that you want to join with the end of the RG-59 type cable.
  3. Mark, or just identify, the coverage on the cable where the large part of the crimping tube ends and the small part begins. This will be about 3/8 or ½ inch (1 cm or 1.2 cm) from the end of the cable. The measurement depends on the length of the long part of the crimping tube you purchased with the BNC type connectors.
  4. Cut and remove the outer cover only by touching it with the knife or using a cable cutter. Be very careful not to damage the aluminum braid that is just below the outer covering.
  5. Unravel the exposed aluminum braid so you can separate it from the polyurethane insulation that surrounds the central copper conductor.
  6. Cuts and separates the polyurethane insulation from the copper core conductor. You can cut it with a knife or using a cable cutter and it should be safari towards the end of the central conductor. Now the cable is ready for the connector and now the cable should only have the exposed copper center conductor and the aluminum braid unwrapped on the external cover.
  7. First slide the crimping tube over the cable with the small end. Before you can slide the crimping tube, you must pull the aluminum braid towards the end of the cable so that the crimping tube can surround and slide directly over the external cable sheath.
  8. Slide the BNC type connector into place, first the small end, with the copper center conductor and the polyurethane insulation going inside the small part of the connector and the aluminum braid and the outer cover staying outside the small part the connector. While pushing the connector on the cable pull the aluminum braid inside the outer cover at the same time. Go inside the connector and make sure that nothing of the aluminum braid has been inadvertently left inside the connector and possibly touching the center conductor. If the aluminum braid is touching the center conductor the connection will not work.
  9. Slide the crimping tube into the outer cover until it is touching the BNC connector. Use your crimping tool to crimp the larger portion of the crimping tube and complete compression fitting of the BNC connector.
  10. When you have completed this you must have two pieces of video cable with a BNC connector in each piece. Use the BNC conceiver barrel to connect these BNC connectors. Now the video cable splice is complete.

Job description of security guard

Security guards are responsible for maintaining the safety of people and property in a specific area. These guards are usually trained for equipment such as alarms, cameras, motion sensors and radios to identify and respond to crimes, fires, medical emergencies and noise.


Security guards monitor and report suspicious or unusual activity to their employers or appropriate authorities; they investigate alarms and noises and remove intruders from property.

Education and training

In most states, you need to have a license as a security guard to work since many employers will train you.

Career development

A security guard can achieve a high position (if the employer uses a ranking system) or become a supervisor or security manager with additional experience.


Security guards normally provide security to armored cars, public buildings (colleges, universities, and government offices), private residences, commercial buildings (casinos, retail stores) or events (carnivals, concerts).

Salaries of computer security specialists

The demand for IT security specialists grows as companies try to protect databases and websites that have confidential company information against corruption and theft. Computer security specialists are some of the highest paid workers in the information technology industry, and the future demand for their services is likely to remain high. The salaries of specialists increase significantly as they gain experience and keep abreast of the latest procedures in computer security.

Functions of the specialist

Computer security specialists develop procedures to prevent people from changing, sharing or deleting computer files from a company without authorization. They review violations of computer security policies and information infractions and make the change of procedures when necessary to prevent future problems. The titles of specialists vary, but they have similar job responsibilities. Information security specialists, information technology specialists and data security managers are just some of the titles that companies give to IT security specialists.


Marketing strategies for a private security company

Private security companies offer a variety of services designed to improve a client’s personal protection. These include offering personnel to protect people or property, conducting threat assessments, providing advice to improve security, conduct surveillance, and conduct private investigations. In order to find customers, almost all private security companies use some form of marketing. Marketing strategies vary depending on the services offered by the company and the market to which they are offering them.


Few clients are willing to hire a security company that cannot offer convincing evidence that they are competent to carry out the required tasks. For this reason, security companies must achieve credentials that indicate that their employees have extensive experience and professional training. Companies should have employees take classes, join professional organizations and obtain relevant licenses. The mention of these credentials by name in print advertising reassures customers that their security is in good hands.

Marketing of the place

Although some private security companies are large enough that they can provide services that suit most customers, most companies must focus on a specific type of security work around which they can base their advertising. For example, a company with extensive experience in private investigations could be promoted as a company that specializes in this area. On the contrary, by naming many services in a single advertisement, many fail to leave consumers with a clear impression of the company.


One of the obstacles that private security companies face in marketing is that many of their previous clients want to keep their relationship with the company confidential. This can make it difficult to get customers through the word. However, some clients may be willing to offer testimonials that testify to their satisfaction with the services the company provides. This provides customers with a means of independently verifying that the company has done a high quality job in the past.

Work in the network

Due to the sensitive work done by private security companies, many clients will only hire a private security company with which they have a personal relationship. For this reason, it is very important that security companies are proactive in creating networks. Having employees make appearances in places where potential customers can meet, such as security fairs, can help spread the word about the company and establish a basic level of trust through personal interaction.


On these dates of Christmas and New Year, some people move to other cities or to the homes of relatives or friends – or simply to go out to party or celebrate a cotillion. Regardless of our case, it is worth bearing in mind that these dates make it easier for thieves and, therefore, the risk that we will suffer a robbery increases.

They are dates, especially during the most marked days, in which the offender knows that if you are not at home, it will take several hours to return. He also knows that the neighbors are at something else and that there is more noise than usual in their homes, so they will hardly hear what happens on their stairs. He also knows that maybe you have prepared gifts of lesser or greater value and without premiering, and that it is possible that you have taken out some cash for these days. He also knows that the security forces are rather “on guard”, and that there is no strong operative against theft.

All this means that, for a criminal, it is easier (less risk to be captured) and, in addition, more attractive (greater possibility of obtaining a booty of easy and quick conversion in cash) commit a robbery.


Fortunately, unless you are an especially appetizing target, you should protect yourself fundamentally from not too professional thieves, who attack mostly by stealing the three minutes. A professional thief will normally attempt higher loot targets; maybe high-end houses, companies or industrial buildings, taking advantage of the alarm and police communication limitations of those hours and dates.

In any case, in addition to having adequate security at your door – security keys controlled and uncopiable , bombs anti bumping , armored shields , security door, alarm and / or safe – it is worthwhile to follow a minimum recommendations if you are absent from home, even if it’s only a few hours.


  • It does not help to have a new armored or security door, if we do not have the precaution of closing with the key.
  • If you have a service key, be sure to block it so that neither the service personnel nor, especially, your environment, which you do not know, could have free access to your home.
  • Make sure your door is not vulnerable to attacks by the 3 minute theft methods. Especially important and simple to install is to have an anti-dumping safety bowser and with VdS ​​BZ + protection.
  • If you trust your close neighbors, it might be a good idea to tell them that you will not be at home and that if they notice something strange they will call you or be attentive to strange noises and people.
  • If you leave home for meals, dinners or celebrations, leave some light and the television or radio on.
  • If you have a safe, deposit your valuables, jewelry and money inside. If you have a key, make sure you do not leave it at home (although it also has an electronic lock).
  • Get rid of gift boxes without giving clues as to what they contained.
    The less you communicate on social networks, the better.
