Every wired Lorex security system records to a box called a recorder, and it comes in two types: a DVR or an NVR. They look similar and do the same job, but they work with different kinds of cameras, so choosing the wrong one means buying twice. Here is the difference in plain terms.
The short answer
A DVR works with analog cameras that connect by coax (BNC) cable. An NVR works with IP cameras that connect by Ethernet cable, usually with power over the same cable (PoE). Starting fresh? An NVR is usually the better long-term choice. Already have compatible analog cameras and cable in place? A DVR can be the simpler upgrade.
DVR: analog cameras and coax cable
A digital video recorder (DVR) pairs with analog cameras. Each camera connects by a BNC cable, and it needs power too. Lorex DVR systems such as the T Series include a 60 ft BNC/DC cable and a power adapter with each camera, so the cabling is covered out of the box.
NVR: IP cameras and one Ethernet cable
A network video recorder (NVR) pairs with IP cameras. The Lorex NVRs below have built-in PoE ports (8 or 16), so a single Ethernet cable to each camera carries both power and video. IP cameras are also where the highest resolutions and newest smart features are found.

What does a channel mean?
A channel is one camera connection. An 8-channel recorder takes up to 8 cameras and a 16-channel recorder takes up to 16. Pick a size with a little headroom: if you need 6 cameras today and might add more, an 8-channel recorder gives you two spare spots, and a 16-channel gives you room to grow. Our guide to how many cameras a house needs helps you size it.

Can I use IP cameras with a DVR?
In general, no. A DVR is built for analog cameras and an NVR is built for IP cameras. Always check a camera's listing for the recorders it works with.
Do I need internet for a recorder to work?
Recording happens on the recorder itself. You need an internet connection to watch live video or alerts remotely in the app.
Are there monthly fees?
The Lorex recorders in this guide store video locally and are listed with no monthly fees.
How much storage do I need?
It depends on the number of cameras, resolution and how often they record. Each listing states the included storage and what it can be expanded to. You can add a surveillance-grade drive from our storage collection.
