Safe as Houses

Find out why NVR (network video recording) is the new gold standard in security systems.

You're probably familiar with the premise of DVR (digital video recording) surveillance, but what are the implications of a network-based system instead? The defining feature of NVR is that it's based on IP (internet protocol) networking, with each camera assigned its own IP address.

Also, unlike DVR systems -- which use analogue cameras -- NVR systems process footage as well as audio at the camera, then send a digital signal via ethernet cable or WiFi to the receiver.

While there are some scenarios in which DVR is still the more practical choice, NVR does have many benefits. Find out more in our detailed guide.

You don't need to connect each camera directly to the recording unit, they just need to be on the same network.

A system that uses Cat5e or Cat 6 network cables normally supports PoE (power over ethernet), meaning you don't need a separate power supply for each camera.

Network cable can run great distances without a noticeable loss in picture quality, so you can cover every corner of your property.

A computer on the network normally allows you to monitor footage without the extra expense of dedicated display hardware.

High-end cameras support 4k ultra HD resolution, to clearly show faces, number plates and other features. Some also have floodlights to allow colour viewing at night.

NVR can easily be set up for push notifications, and in general, natively supports access from mobile devices.
