I am considering buying this box since it appears to offer a way for me to make use of the 12 bnc cable runs I have in my home. 8 of my cameras are 480TVL and I have 4 that are 700TVL and they are all recording at CIF. I am trying to understand what is the difference I will see if I buy this DVR? I get that it has the potential to record and stream to remote devices a higher resolution of D1 and that will help, but at what frame rate? The TRIDVR-ELE16ME the spec sheet shows a
Main stream record rate of 1080P(1-15fps) / 720P/960H/D1 (1-25/30fps) and an
Extra stream record rate of CIF/QCIF(1-25/30fps).
For instance, assuming 10fps is possible, but if this too high for this box:
Can this box record and stream to remote viewing D1 at 10fps to ALL 16 channels at once? (assuming I have my current cameras)
Can this box record and stream to remote viewing 960H at 10fps to ALL 16 channels at once? (assuming I had all 960H cameras)
Can this box record and stream to remote viewing 720P at 10fps to ALL 16 channels at once? (assuming I had all HDCVI cameras)
The specs for this box shows a bit rate of 96-4096Kbs, but I am not sure how this translates to answer the above ?s
I don’t mind doing the math, if someone can show me how. Thanks / Mark

That DVR/NVR will run 16 channels simultaneously.
You will be able to record and stream video to remote clients at the full frame rates =
At 1080p (2Megapixel) you can run all channels at 15 FPS (frames per second)
At 720p (1 Megapixel) you can run all 16 channels at 30 FPS
At 960H / D1 / or lower resolution – you can run all channels at 30 FPS
You can mix speeds also – 1 cam at 10FPS, another at 30FPS – they are individual settings.
On your existing cameras, you will not see much difference in quality.
With the unit you can add HD-CVI cameras at 1 or 2 megapixel and then you will see a huge difference.
Or you can add 2 IP cameras and you will see a huge difference. (IP cams will go to channels 15 and 16)
As long as your existing cables are good quality, you can use them for HD-CVI cameras.
The bit rate is a little different setting – this is the amount of data used to ‘fill in’ an image.
The 2 megapixel HD-CVI cams will use a bit rate of 2048Kbps or less. (They don’t need to be that high)
In most cases with analog cameras and HD-CVI cameras you won’t need to worry about the bit rate – that comes into play more with IP cameras at higher resolutions (3Megapixel and up)
To sum up – the answer to all of your speed and streaming questions is ‘Yes’ it will do that easily.
Let me know if that helps.
