Hi,
Can someone please confirm the following about the GV-1480 card.
The card can record 16 channels at 25/30 frames each at D1 or 4CIF quality
If this card can not is it possible with another card. I have seen different cards advertised as "16 channels- 480 fps at 4CIF"
Would this provide really high quality video.
I have 540 TVL cameras but there is no point of those until the DVR can actually record at the same resolution?
From what i understand: When we connect a 540 TVL camera directly to a monitor we see very clear quality video. This is because the monitor is showing the full resolution. But when we connect the same camera to a DVR, the video is digitised. Computers usually digitise using CIF format which degrades the video quality. Unless the DVR is of very high spec and can record at the same 540TVL resolution we will not be able to record the same quality as the monitor.
Is compression also a factor? Does it degrade video quality and is there any way to overcome this?
I may be wrong so please correct me. Is it currently possible to record 16 channels at near DVD quality on full frame rate in todays date
