Who is it for?
An NVR is the heart of an IP CCTV system. It records the cameras, powers them over the network cable where it has PoE ports, and provides remote viewing through an app. Choose the channel count for the cameras you have plus room to grow — an 8-channel recorder costs little more than a 4-channel and saves replacing it later.
Choosing the right recorder
- Channels. One per camera. Buy above your current count if you may expand.
- PoE ports. Built-in PoE powers cameras directly. Without it, you need a separate PoE switch.
- Maximum resolution per channel. An 8MP camera needs a recorder that records 8MP, or it will downscale.
- Drive bays. More bays means more retention. Two bays suits a busy commercial site needing 30 days.
What you will need
- A surveillance-grade hard drive — we fit and format it before dispatch or collection.
- Cat5e or Cat6 cable to each camera and a network cable to your router for remote viewing.
- An HDMI screen for setup; day to day most people use the app.
Frequently asked questions
Is there a monthly fee?
No — recording is local to the recorder and the app is free.
Can I use cameras from another brand?
Usually yes over ONVIF, though brand-specific analytics may not carry across.
How much storage do I need?
It depends on resolution, camera count and retention. Tell us the setup and we will size it.
Can I order it as a CCTV recorder with hard drive?
Yes. Pick a hard drive of up to 6TB from the Hard Drive option on this page, or order the recorder only. It has one SATA III port.
