Surveillance systems typically use closed circuit television cameras for residential and commercial properties. 8 channel DVR and 16 channel Dvr systems are used for storing recorded video. The best security cameras are considered ones that have motion detectors. Motion detectors allow more control over what is being recorded, and a drastic amount of space is saved by using motion detectors. Wireless systems provide additional convenience for implementing a security system for a variety of property types. Wireless security systems do, however, require a line for power, but all other elements are transmitted wirelessly.
