NVRs that are not device specific?

[trauts14 0]

I am not sure if most NVRs are device specific. Can anyone suggest a NVR to use with IP cams that will will reguardless of the make or model of the IP cam? I have a couple of different brands of IP cams and would like one NVR to record them all.

If your cameras are ONVIF they MIGHT work with a ONVIF NVR.
