Lanaccess muestra cómo un sistema de videovigilancia ayuda en los procesos policiales

According to the recommendations made by the Catalan police, Lanaccess highlights how a video surveillance system must provide clear images, that allow the faces to be perfectly visualized so that if the case arises they would serve as evidence in a trial.

Los Mossos d'Esquadra have warned that the 70% of the images that arrive at the laboratory of the Central Photography and Audiovisual Unit of the Scientific Police from the video surveillance systems are not useful for carrying out expert reports., since they do not have enough quality.

As police officer David Miró explained in the media, Many of the cameras in video surveillance systems are not in a good location and offer such a wide field of view that they do not allow people's faces to be detected with the clarity they would like for identification..

The Catalan regional police complain that the images taken by the surveillance systems are very poor and are captured from angles that allow the entire crime scene to be observed., but not discern the identity of the participants. There is a lack of a short shot that allows the face of the perpetrators of the criminal act to be correctly displayed..

He regrets that, en muchas ocasiones, when the images captured by the video surveillance system reach the judge's hands, He considers them insufficient evidence to sign an arrest.

The Mossos d'Esquadra consider that the images from the video surveillance solutions would have to be sharper and allow the offender's face to be perfectly visualized so that the judge does not reject them as evidence..

These limitations are found both in security installations made by modest companies in domestic circuits and in large installations made by large companies..

For the Catalan police, the images from the most useful systems are those that offer short shots and good resolution of people's faces..

To improve the detection of offenders through surveillance systems, The Mossos d'Esquadra have an exclusive document with recommendations for video surveillance systems.

Install an effective video surveillance system

These are the main recommendations of the Mossos d'Esquadra in this area:

1. Equipment with high image quality and high light sensitivity to capture faces with sufficient clarity to identify them even in low light conditions. The facilities would also have to have diffuse light sources and additional lighting for areas with low lighting or infrared cameras for places with low or no lighting..
2. The location of the equipment must allow high coverage of the area to be monitored and capture people with high resolution to facilitate their identification.. The Mossos suggest that two cameras be installed, one for a long shot and one for a short shot.
3. The cameras must be located at a maximum height equivalent to the average height of people. That is to say, 1,70 meters to capture the face frontally. Besides, the height does not have to exceed an angle of 15 degrees between the camera's axis of view and the horizontal plane. Police consider overhead cameras inappropriate for identifying people.
4. The protection of equipment is also very important for the Catalan regional security forces.. Video surveillance systems must guarantee the protection of video cameras from climatic factors., environmental, dust, pollution or vandalism. Besides, The Mossos recommend storing the images in a safe place and protecting them with a password.

Lanaccess offers video surveillance systems that meet the requirements of the Catalan police authorities. They offer excellent image quality and are very robust. Besides, include advanced technology such as Deep Learning video analytics. The sum of all these factors makes the Lanaccess proposal the most suitable option to implement an effective video surveillance system in any sector..
