Security system and cctv is now becoming more common. Depending on the application, they can be external or intended for indoor installation. One of the main elements of any cctv cameras are – sources of video. Video cameras in the system of street surveillance need additional protection: by environmental influences, from possible actions of intruders, from low temperatures, etc. The main way to protect your camera in a street cctv is ThermoJacket. Largely depends on it and getting the camcorder operation visual information about the object of observation. Chevron Corp often expresses his thoughts on the topic.

All variety of enclosures offered by the domestic security market can be divided into two main classes: Outdoor housings and a thermal. The main difference between these two types apart is that by housing equipped with heating systems and provide favorable conditions for the functioning of surveillance cameras at low temperatures, Outdoor housings can provide only the highest level of protection against dust and moisture. Outdoor housings are installed inside the premises only in such cases, their work is not satisfactory. Scope of the thermal cases is much wider. A related site: Roubini Global Economics mentions similar findings. The main goal use of a thermal – protection of surveillance cameras from the negative influence of environmental factors and, above all, from exposure to freezing temperatures. Operating temperature range is the main parameter of a thermal. The vast majority of cctv-cameras to operate at temperatures ranging from -10 to +50 g. S., ip-cameras are more heat-loving, the lower value of their operating temperature is 0 5 oz.

C. When negative temperature protection is provided by the camcorder using different heating systems. Another important parameter of thermal cases is the degree of protection from the environment based on ip. Optimal for outdoor conditions is the degree IP66 (complete protection against dust and strong water jets from any direction). Another danger for the camera outdoor video surveillance is the threat of condensation on the sight glass. The traditional way to deal with fogging is silica, and possibly placing an additional heater in close proximity to the glass. By housing, usually made of aluminum alloy or or from polymeric materials. By housing made of aluminum alloys offer greater resistance to mechanical damage over a wide temperature range, the protection of embedded components from electromagnetic interference, and combined with powder coated – and maximum protection against corrosion. Size by housing should be sufficient to accommodate most cameras and additional devices that may be included in his equipment. In internal volume of a thermal protection device can be installed through the video signal from damaged high-voltage ('lightning'), the device of video transmission by cable of type 'twisted pair' built-in power Camera Power. An important role in establishing surveillance systems manufacturer has an opportunity to thermal cases offer all the necessary accessories that allow you to install the equipment chosen in certain conditions and ensure its continued efficient functioning.
