A wide range of CCTV cameras are available. These include external weather-proof cameras, Infa-red night vision cameras, dome cameras and covert cameras. A digital video recorder (DVR) can be used to record camera footage to an internal hard drive. This can be reviewed at a later date and burned onto CD as evidence that can be submitted to the police. Access to the CCTV cameras and recorder playback can be gained remotely via the internet from your PC.
