Disguised Security cameras and other systems
Security cameras can be disguised as lamps or toys. They can also be made visible to act as a deterrent to intruders. Some cameras use the 2.4 GHz frequency range, which is more resistant to interference. These cameras provide superior signal and good picture quality, as compared to other devices.
Color security cameras are more expensive than black and white ones. They are also not as sensitive as black and white cameras. Color cameras are not a good option for night time monitoring, unless there is a lot of light. A few security cameras have a filter that enables them to function as a colored camera in day time and as a black and white camera in the night.
In a CCTV system all components are directly connected or linked by wireless. The camera has a CCD (charge coupled device) sensor that converts light into a video signal. The half-inch chips, which offer the highest resolution and sensitivity, are also the most expensive. Third-inch chips are becoming more popular, due to their improved performance.
