8 channel DVRs
An 8 channel stand-alone digital video recorder is able to accept images from up to 8 CCTV cameras and record all of these at the same time on to its built in hard drive. Some can record 25 images per second (real-time) from each camera, this data can then be backed-up onto USB Pen sticks, CD-RWs or DVD-RWs depending on the DVR, some can even be connected to the internet and viewed remotely from anywhere in the world.
