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. Today, increasing numbers of domestic households adopt CCTV systems as a common means of protection and communication. CCTV systems are used mainly in large public areas like: banks, malls, train stations, sport stadiums and in almost every large store. The receiver's output can be stored in a VCR, DVR or viewed in real time on a TV or computer monitor. Cables and wiring Something to note, if you have a laptop rental and plan to use wireless accessories be sure to ask if the equipment is wireless capable. It is OK to do it this way, for baby monitoring or residential application, when quality of the picture is not that important. Therefore many customers shopping for complete CCTV monitoring and recording systems are confused by such a veriaty of available products. Spy cameras CCTV cameras are usually divided into different types based on the body of the camera used:

Another idea is to put a security yard sign informing that the house is monitored around the clock. Today, increasing numbers of domestic households adopt CCTV systems as a common means of protection and communication.

There are three main types of IR illuminators: diodes, lamps, and lasers. Diodes are small, inexpensive, and good for short-range illumination. They also require relatively little power to operate. Infrared lamps are more expensive to buy and maintain, but they can operate at greater distances and are often better for facial identification. Lasers are excellent for long-range image clarity, even in inclement weather, but they're big, expensive, and potentially harmful to the eye if not handled correctly-which is why they're usually only reserved for military use. Standalone Systems Selecting the right surveillance cameras We recommend this type of security cameras for commercial installations. However, higher density 1/4" and 1/3" CCD chips can now produce as good an image as many 1/3" or 1/2" chips. CCTV Camera Types How Do Infrared Illuminators Work? For a common size household, the most suitable system is a quad cam. The distance from the monitoring object to the camera is not an issue here, that is why the ability to select different lenses, based on camera location is so important. Each group differs from the other by means of function and size, although some features are shared by both groups.

CCTV cameras are usually divided into different types based on the body of the camera used: Infrared technology is simply LED light in infrared spectrum (not visible to the human eye).
