Wireless cameras are also used for CCTV systems but only few opt for this type because of the threats of being hacked into its system. To understand how CCTV system works, it is better to know its two types, namely the analog CCTV and the IP-based CCTV. Analog CCTV security camera has set of wires that are fed into a recording device and series of monitors.
The smaller the camera, the lower the resolution.So, it is mostly a compromise between size and quality. A smaller spy camera can be easily veiled but then the quality may not be what you desire. On the other hand, a larger spy camera may allocate you great condition of audio and visuals, but you may have problems in keeping it hidden.
You can choose a camera that takes only still pictures or a camera that files videos and sound. Some cameras are equipped with night vision if you want the monitoring to be done mostly in the nighttime. There are also cameras that are motion-activated. They set to operate only when there is a movement in the area of their scrutiny.
