Lanaccess shows how a video surveillance system helps in police processes

According to the recommendations made by the Catalan police, Lanaccess highlights how a video surveillance system should provide clear images, that allow to visualize perfectly the faces so that if the case will arrive they will serve as evidence in a trial.

The Mossos d'Esquadra have warned that the 70% of the images that reach them to the laboratory of the Central Unit of Photography and Audiovisuals of the Scientific Police by the video surveillance systems do not serve them to make expert reports, as they do not have enough quality.

As explained in the media by the policeman David Miró, many of the cameras of video surveillance systems do not have a good location and offer such a wide field of view that they do not allow to detect the faces of people with the sharpness they would like for their identification.

The Catalan regional police complain that the images taken by the surveillance systems are very poor and are captured from angles that allow to observe the entire crime scene, but not discerning the identity of the participants. It misses a short shot that allows to correctly visualize the face of the perpetrators of the criminal act.

Regrets that, on many occasions, when the images captured by the video surveillance system reach the hands of the judge, the latter considers them insufficient evidence to sign an arrest.

The Mossos d'Esquadra consider that the images of the video surveillance solutions should be sharper and allow the face of the offender to be perfectly visualized so that the judge does not dismiss them as evidence.

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

For the Catalan police, the images of the most useful systems are those that offer short shots and a 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 sharply enough to identify them even in low light conditions. The facilities would also have to have diffused light sources and additional lighting for areas with low luminosity or infrared cameras for places with low or no illumination..
2. The location of the equipment has to allow a high coverage of the area to be monitored and capture people with a high resolution to facilitate their identification. The Mossos suggest that two cameras be installed, one for a general plane and one for a short plane.
3. The cameras must be located at a maximum height equivalent to the average height of the people. I mean, 1,70 meters to capture the face frontally. In addition, 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 the equipment is also very important for the Catalan regional security forces. Video surveillance systems have to ensure the protection of camcorders from climatic factors, Environmental, Dust, pollution or vandalism. In addition, 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. In addition, include advanced technology such as deep learning video analytics. The sum of all these factors make the Lanaccess proposal the most suitable option to implement an effective video surveillance system in any sector.
