CCTV NVRs

Choosing a replacement NVR

An NVR records from IP cameras that send their video over the network. Each camera connects with an Ethernet cable, either to a switch or straight into the recorder. Many models in this range have PoE ports, which power the cameras through that same cable, so no separate power supplies are needed.

Pick by channel count

Match the number of IP cameras you have now, and allow for any you plan to add.

• 4 channel NVRs for a handful of cameras.
• 8 channel NVRs, including PoE models with eight camera ports.
• 16 channel NVRs for mid-sized systems.
• 32 channel NVRs for the largest layouts we list.

Replacing an old network recorder

Start with the label on the failed NVR and note its model number. Then check three things:

• How the cameras are powered. If they take power from the old recorder's PoE ports, choose a replacement with at least as many PoE ports. If they run from a separate switch, a non-PoE model will do.
• The camera brand and model, because the recorder must be able to add them. Mixing brands is possible on some recorders but not all, so check before buying.
• The hard drive size, so you keep a similar amount of recording time.

If your cameras are on coax cable instead, you need a DVR or an XVR. The full range is on the recorders page.
