  Reply with quote      
I have just purchased and linked up an AV760 - Model 3. Everything works great but when I backup recordings they always appear as a split screen showing all four cameras. If I play them on the box itself I can switch between the four cameras so I now they are recorded separately.
What I need is to be able to backup the 4 cameras individually.
I feel sure this most be possible. Can anyone help please?
Thanks

Go into config - network - backup. Lets you backup recorded video one channel at a time. (Video Server E) Hope this helps.

Thanks for the reply
I think the problem is the selection of "frame" or "cif". If I select "cif" I get all 4 channels everytime I use the backup regardless of the channel I select. It appears that if I use "frame" I get the 4 channels separately.
I just hope I still get 25fps on all 4 channels if I use "frame". The manual isn't very clear on it.
Does anyone know what "cif" stands for?

Thanks for the links.
It would appear that I don't get 25fps when I use "frame" and more than one channel. Very dissapointing.
If anyone had been able to use the AV760 to record 25fps at full size for all four channels I would appreciate information on how they achieved it.

It appears that you are recording PAL 25IPS. (Frame).

IPS per channel = RECORD IPS ÷ 4 channels = 6.25 per channel.

Number 10, page 15.

CIF PAL 100IPS ÷ 4 channels = 25IPS per channel.

That is true, but when I select CIF and 100fps I cannot download the channels individually. Whether I select Channel 1,2,3 or 4 I always get the split screen downloaded showing all channels.
