When most people think of hidden cameras they immediately think of the nanny cams on the market to help parents monitor how their children are being cared for when they're not around. Determine exactly what your viewing needs are, and which functions you expect the camera to serve. it is well worth it to invest some extra money toward purchasing a good quality digital video recorder (DVR). Video tapes tend to deteriorate quickly, recording quality declines rapidly and you'll constantly be spending money on new cassettes. Today, increasing numbers of domestic households adopt CCTV systems as a common means of protection and communication. Any camera installation will require proper wiring. The larger the number of TV lines, the better the resolution and hence, overall picture quality. Of course there are. But the trouble with non-wireless, or fixed, security cameras is that they require expensive cabling and valuable time and energy to install-and then, after all that effort, they're stuck in one place. CCTV Camera Types These cameras may be packaged in a small case (Mini Cameras) or dome (Mini Dome) or simply sold unpackaged, for mounting by the purchaser.

An IR-illuminator is a device that emits infrared light-low frequency electromagnetic radiation that's outside the visible spectrum. In other words, it gives off light that a camera can pick up and use, but that a person can't see-so while it's still dark to the human eye, the camera can see just fine.

Security Monitors Just as in digital cameras and computer monitors, resolution refers to the quality or the sharpness of the picture you'll receive. Special brackets and tile clamps can support a camera destined to be located in difficult positions. Whereas cables can only go so far before the signal goes bad, wireless transmission can send clear, high-quality pictures all the way across the globe. In short runs plug and play non-coaxial cables with factory installed BNC connectors may be used (up to 150 ft.).

Since the lenses in board cameras are pre-mounted, have a fixed iris and are usually of a short focal length (i.e. wide angle), their flexibility of usefulness is limited. For short-range transmissions (to a police van around the corner, for instance), a WCCTV camera may beam the signal point-to-point-that is, straight to the receiving device.
