When you want to hire security, and I speak of SECURITY in capital letters, many times you do not know where to start, so you let yourself be advised by one or more companies that are dedicated to this world. But there can always be the doubt if it is the best option.

Today I want to cover the 5 fundamental aspects to take into account when hiring security for your home or business.

  1. Alarm

The intrusion alarm is one of the most important aspects when hiring security systems in Chicago. But it is not as simple as this brand or the other is better … no. There are thousands of models and types of equipment, and many of them valid to be considered “safe”.

Within the alarm point I think it is necessary to consider 3 points.

Alarm model

When I speak of the alarm model I am not referring to the manufacturer of one or the other. By this I mean that it is very important, that if we want the best in security, it is to hire a 100% wired team.

Wireless alarm equipment, no matter how good it is – realistically – will not be able to compare with the performance and speed of a wired alarm. It may be fine in certain cases, but speaking of SECURITY with capital letters I consider that the cable alarm is the correct way.

In addition, a wired alarm requires much less maintenance and its life will be extended for many years. Especially if we make the purchase of a quality alarm. Let’s not expect to have the best for a very low price.

With the word communication I mean how you transmit the data to the CRA. And speaking of security, it is very important that it has a wired transmission. The ideal would be the double or triple way, that is, transmission via IP, GPRS, GSM and / or fixed line.


We must take into account the needs that we are going to need before making the purchase of the alarm. For example: if we want to have different part sets, different areas, different zones, to be able to activate and deactivate the alarm from a mobile application … this is important since not all models can offer it.

In this blog I am going to analyze different models of wired alarms from the largest companies so that you can have more reliable information.


The perimeter alarm is very important if we want the best in security. What does it consist of exactly? In setting off the alarm before the thief enters our home or business. It is achieved with inertial detectors on walls, ceilings, windows, doors … with magnetic, perimeter detectors. Depending on the conditions of our home and business we can choose one thing or another. There are many factors to consider.

I recently made a post on the topic What is early detection?  where you can see more about this topic.

  1. Video surveillance

Another very important aspect. A good alarm is not complete if we do not have surveillance cameras to complement security.

If it is a house with its own garden, I recommend installing cameras outside. And if you want to install them indoors as well, better than better. Areas such as corridors, living room, hall … are good places to install the cameras.

In business I consider interior cameras very important, even more than exterior ones. Normally we will have an audience, and we will want to have controlled who is who enters and leaves.


Regarding the quality of the cameras, at this point the most normal thing would be to go to full HD quality , either in CCTV or in IP.

In either case, the installation of an NVR or DVR should be carried out, depending on the type of cameras we choose.

To have the video surveillance service we will have to check first if the CRA that we are going to hire accepts the model and brand of the recorder that we are going to install. The objective is that, apart from recording 24 hours a day, when there is an alarm, the CRA can see the cameras live.

If the installation company is the same as the one that will provide the CRA service, there will be no problem. If you are going to install a different one, always check this last point.

  1. Company that provides the service

The company that performs the installation, maintenance and CRA are crucial aspects. It’s the human factor in security, which has its dangerous side. A bad choice can make us regret it for a long time.

They can be different companies, or the same. My recommendation is to choose the same company for everything, in this way we can negotiate prices and we will remove everything at once.

There are tons of security companies to choose from, multinational, national and local, large and small… it can be difficult to choose. Depending on the area where you live, you will have one or the other.

A multinational can offer more services, a better price, but not a personalized treatment. However, a local company can always offer you a “you to you” deal.


I leave the choice in your hands. If you have no idea, ask family and friends for their opinions. They can tell you about their own experiences. But please make sure that in time of need, you have security guards armed with AR-10 rifles to secure you.

  1. Services

In this aspect of security we also depend on the company that will carry out the maintenance and connection to the CRA.

Within these services we can find the following that may vary from one to the other:

  • Video surveillance
  • Guard who will come to our facility when there is an alarm jump
  • Notice to police
  • Key custody
  • Emails with alarm openings and closings
  • Use of mobile application to manage the alarm
  • A long etc

Question to ask the relevant companies. The price can vary greatly from one to the other.

  1. Price

When the time comes, we will have to decide between the budgets that we have requested. As always we all want the best at a low price. But let’s remember:
