PC Based Digital Video Surveillance Capture Cards
PC Based Digital CCTV Surveillance systems are a reasonably new technology in the CCTV Industry. This type of Digital CCTV system works in two stages. You then install the digital cctv surveillance card and software on to your PC. This Software (or program) will allow you to view your Digital CCTV Cameras, search through previously recorded footage, backup footage to CD/DVD, control PTZ Cameras either on the PC system or remotely and much much more.
Cameras are attached to the back of the Geovision PCI Card using the standard BNC connection used in all CCTV Cameras.
Geovision Surveillance cards come in a variety of formats depending on 1) The amount of cameras required (2-16)
2) The Frame Rate per Second (FPS) Quality required (16 FPS - 400 FPS)
Frame Rate is important, as the higher the Frame Rate, the higher the quality of recording and the more Real Time your cctv recording will be.
Real Time Recording for 1 camera is 25 Frames Per Second (PAL). In order to capture 16 cameras in Real Time, you would need:
25 FPS x 16 Cameras = 400 Frames Per Second PCI Surveillance Card
