The fixation of what is happening at the workplace or at home will help to fight crimes in one case, and in the other to help prevent them. But there is one tangible minus – buying and installing video surveillance in specialized agencies is a very cost action, especially for small organizations. Therefore, you should independently address this problem, but first you should study some rules for choosing a video surveillance system.
Decide why you need a video system – street or internal observation. In the first case, you should choose models of cameras with a protective casing, with a system of cleaning the lens from pollution, anti -vandal systems. Inexpensive cameras are suitable for installation in the room.
Determine the degree of review of the observed object. To do this, you can choose a model with a rotary mechanism, or with a large focal length, which allows you to study the object in detail when approaching. You should also take care of the high resolution of the cameras, since the low resolution will not allow you to accurately determine the details captured by the camera. Also determine the observation time, since standard cameras will not be able to qualitatively display what is happening at night and gloomy time.
Decide that the installation of video surveillance systems should be persecuted – to prevent or help to disclose offenses. In such cases, you should choose either open video cameras or hidden observation objects. In addition, open cameras should be installed in hard -to -reach places and have increased strength, which greatly increases their cost.
Calculate the required number of cameras and determine the number of possible records. The standard office set consists of four cameras, the signal from which comes to the recording device, a video fixer that enters the hard drive is currently used. If you need long -term storage of a large number of observed events, then purchase models with a voluminous hard drive and effective compression methods.
Decide on the security place, it will be necessary to carry out a cable there, if it will have to be removed then, but the most modern way will be to connect the camera to the computer network and the video signal transmission by local connection.
A number of these rules will allow you to easily choose a suitable video surveillance model at a low price.
