A security is a growing concern for companies, and with the wide range of solutions available, choosing the ideal products for each use case can be a challenging task. With this, PositivoSEG, Positivo’s division specializing in electronic security, provided tips on how to develop an efficient system for different environments.
Among the segment’s offerings, one of the main ones is CCTV (closed circuit television), which provides visual evidence in the prevention and investigation of potential crimes, in addition to giving a greater sense of confidence to those who frequent the environment. There is also an emphasis on alarms, sensors, access control and connectivity products.
Closed circuit television is mainly composed of a set of surveillance cameras installed in strategic locations, such as the entrance to a corporate building and the common area of a condominium. These cameras transmit images to a central system, where they can be viewed in real time or archived.
There are different types of surveillance cameras, and the most used are:
dome camera: very discreet and ideal for indoor environments. It is usually installed on the ceiling or upper part of the walls. Some models have infrared sensors, making it easier to identify objects and people in darker places;
Bullet camera: stands out for its more prominent appearance, which attracts attention. It is recommended for external environments in corporate buildings;
fisheye camera: like the cameras used by professional photographers, this camera has a “fisheye” lens that offers a very wide field of view, ideal for indoor environments and can be useful for different types of establishments;
PTZ or Speed Dome Camera: stands out for its ability to move the image horizontally and vertically, and can also have optical zoom to enlarge the image without loss of quality. These models are recommended for monitoring wide areas.
Sensors are also essential in cases of theft. Establishments that have barrier or opening and closing sensors can emit audible alerts through alarms that draw the authorities’ attention to some type of suspicious movement, vandalism or break-in, for example.
Barrier sensors work with a beam of light that delimits a line in a passage — such as a door — and so, if something crosses that line, an alarm is immediately triggered. Opening and closing sensors, as their name suggests, monitor the opening and closing of doors, windows, drawers and other objects.
To ensure maximum efficiency of these devices, it is ideal to have a network system that allows the owner of an establishment to monitor the security status of the location. As an example, some surveillance products include applications that make it possible to view the video feed from cameras, even from a distance.
Finally, access controls are devices capable of storing biometric data — such as fingerprints, iris or face — or identity cards of people authorized to visit a private environment. An example is the storage of medicines in a hospital, an area that should only be accessed by authorized professionals.

Other solutions may include devices protected by a numeric password that function as smart locks, as well as turnstiles for environments with a flow of people and gates for the flow of vehicles.
PositivoSEG highlights that it is essential to request installation by certified professionals, who guarantee regular maintenance and carry out technological updates from time to time, as highlighted by José Ricardo Tobias, director of IoT at Positivo Tecnologia and responsible for the company’s electronic security division.
It is worth remembering that home security is as important as corporate security, and smart home devices, which are increasingly present on the market, are an effective way of ensuring environmental protection. So, be sure to check out our tips for surveillance cameras and smart home devices.
