Recommended Video quality setting for HIKVision DS-7608NI-I2 / 8P

[Connectome]

I have a new NVR and it has 7x cameras which are DS-2CD2385G1-I.

I would like some advice please as to the recommended bit-rate and image quality that I should use. My storage capacity is 12TB, thank you.

Many here run Constant instead of Variable.

Many have found 4K needs a min of 8192 bitrate.

Most find H264 with smart codec off provides the best performance.

Most find that FPS of 15 with an iframe interval of 15 is all that is needed for surveillance.

As always, YMMV.

just to confirm,15fps using H264?

Thanks, how do I change the codec from smart?

The codec is the + that you have as ON. Turn that off so it only runs H264 and not the plus.

Ok, is h265 lower quality?

H265 in theory provides more storage as it compresses differently, but part of that compression means it macro blocks big areas of the image that it thinks isn't moving.

In theory it is supposed to need 30% less storage than H264, but most of us have found it isn't that much. When I tested it, it was literally a few minutes difference over a 24 hour period. And I thought the H264 looked better.

As always, YMMV. If you do not see a difference in video quality, then go with H265 as it does save some storage.

Thanks, I’ll give that codec a whirl and change the bitrate to 10000kbps from 6000
