Colorvu Acusense Bandwidth Limitations?

[rolson]

I am looking to purchase the following NVR:-

Hikvision DS-7608NI-I2-8P 8 Channel​

With the 8 camera options, I was entertaining the idea of possibly 8 cameras of the following model:

DS-2CD2387G2-LU 8MP 2.8mm​

Will there be bandwidth issues if I go ahead with the combination proposed?

Hi @rolson

You definitely will run into issues fully loading it with DS-2CD2387G2-LUs.

We're finding that these cameras are using 20-25 Mbps each when set to their maximum frame rate and video quality, at their highest compression settings. This is significantly more than the older 8MP cameras and thinks it relates to the AcuSense features that have been added to the cameras.

To guarantee a stable performance without dropping any of the video settings you will need an I-Series NVR with a bandwidth budget of around 200 Mbps - the smallest would be the DS-7732NI-I4-16P, which has a 256 Mbps budget.

What about the 4MP variant of the ColorVu turrets . How have you found the bandwidth usage when these are dialled up vs the newer 8MP variants?

I was looking at the same above NVR for the following cameras :-

1 x DS-2CD2387G2-LU. (8MP)
3 x DS-2CD2347G2-LU (4MP)
2 x DS-2CD2042WD-I (4MP)

Slightly worried I might start pushing it too hard.

Thanks

Im thinking the DS-7616NI-I2-16P 16 Channel might be a better compromise for me. Reading the specs, it has 160 Mbps on the incoming stream - so double the Hikvision DS-7608NI-I2-8P 8 Channel

The NVR specs are a maximum of 8 cams or 80Mbps incoming bandwidth whichever is reached first. It's always best to allow plenty of wiggle room so the 16 channel works better in that respect.
