Checking the NVR's technical manual, it input bandwidth max as 160 Mb/s. That's not that high, especially if you are using (90) 2MP cameras.
What's your frame rate for these cameras? Do you have a sense of the bitrate the average camera will consume?
sorry for the delay in reply. We need a frame rate of 20-25fps per camera and also a bit rate of 6.
As John states, the unit has a bandwidth cap which is total for all cameras. You also need to consider the storage requirements for that many cameras on a RAID unit .
nit which will reduce the total storage available. At 2MP/25fps, that will be consumed quickly. I believe you will need additional units but I suggest you contact the local office for detailed support

Thanks Bob for the feedback.
If you are using 6Mb/s per camera with 90 cameras, you will need 540Mb/s total throughput. That's more than 3x the stated throughput of this unit.
As Bob says, check with the manufacturer, both for information and so you have a defensible position if it doesn't work ;)
The unit is designed for up to 64 cameras with an average bandwidth of 2.5Mb/s per camera. The bandwdith allocation is flexible per channel.
A minimum of 2 units was always required for 90 cameras - if 6 Mb/s is really required (seems a bit high to me), then 3 or 4 units will be needed. Again, best to contact the lcoal office.
Thank you all for the support
