Digital video home surveillance systems have changed the concept of security drastically. Video has become an important part of facilitating effective home surveillance. This basically involves the incorporation of a closed circuit TV network that is applied within a restricted area. At present, wireless video home security systems are becoming popular as they not only allow easy and efficient surveillance of covered areas but are easy to install and can detect smallest of the abnormal activities within the coverage periphery. The greatest benefit however remains that this surveillance system allows vigilance without manual surveillance.
The main components of a Video Home surveillance systems are as follows-
Cameras- These are very important components of a video surveillance system. They are the means by which any unprecedented activities are caught and relayed to the monitor at the central control panel for requisite action. It can be of two types – the conventional black and white camera or the more advanced infrared CCD cameras that can function even at night. The traditional black and white cameras have their limitations as their lens power is restricted to day light. They fail to perform efficiently at night or when the source of light is very dim.
Monitors – These are the units on which the images caught by the camera gets displayed. Part of the personal computer, both can act as a monitor. Video recorders can be attached to these systems so that the activities relayed get recorded. Quad process can be one of the ways by which you can record as well as replay.
Cables- Cables are needed to connect the cameras to the monitors and the alarm. In the modern home surveillance systems the function of cables has got limited as wireless systems have taken the market by storm.
Surveillance software- If you have a wireless security system that is based on an IP address router then you will require surveillance software to get installed in to your PC. This will help your Personal Computers receive signals from the camera and store them on the hard disk. The surveillance software starts recording only when it caches abnormal movement in the covered area. They are programmed to trigger off alert messages to your controller and also to your mobile phones.
Home Surveillance systems are no longer limited to the perimeters of the house. With the easy installation of CCTV cameras and infra red sensors any kind of movement can get detected irrespective of whether the security system has been installed within the walls of your home or outside.
