NVR to record Footage using IP Cameras over a Network
Our new range of HD IP security cameras are ideal for advanced home or business security, recording crisp footage in glorious HD. Unlike traditional analogue CCTV, IP cameras use built-in processors to record video as digital information. This enables them to send information down network cables- just like you use for home internet- as opposed to standard AV cables. Whilst this means you can connect them directly to a router to view over the internet, it does pose a question- how do you connect them to a recorder? After all, CCTV DVRs use analogue BNC connections for video. The answer is by using an NVR, or Network Video Recorder.
As the name suggests, cameras connect to an NVR over a network, as opposed to being directly plugged in. Like all of our CCTV recorders, our new 8 camera HD NVR features adjustable Motion Detection triggering, allowing it to remain on standby until movement in any one of the cameras initiates recording. You can also schedule recording and motion detection times separately for each camera on a 24 hour 7 day schedule. Just like our LAN DVRs, you can also log in to them using a web browser or mobile app, letting you monitor your live CCTV footage remotely. Don’t let these similarities fool you however, as there are some quite major differences in how they work and are set up.
Connecting to cameras
Because NVRs are designed to connect over a network, there is no need to connect your cameras directly. Once your IP cameras are connected to your internet router, you can connect the recorder to the same router and it will automatically detect the cameras. This makes it much quicker to get your recorder wired up. It also allows you- using one of our powerline adapter kits- to install the recorder in a totally separate room, keeping your recordings out of sight and secure.
When you connect a CCTV camera to a DVR it needs to use dedicated hardware in order to convert that analogue signal into a digital video that it can store, a process that loses some image quality. With IP cameras, this processing is done by the camera itself. This not only means that there is no image quality lost in the conversion process, but that the recorder can be more compact, as it needs less internal hardware.
The number of cameras you can use with a DVR is partially restricted by the number of video inputs on the back of the unit. As NVRs do not have these physical video inputs, the only things really limiting this are the software and the size of your hard drive. Our new HD NVR for example, can record up to 8 cameras in full 1080p resolution, or alternately drop down to D1 resolution (720×576) in order to work with up to 16 cameras. Combined with the simple wiring, this makes IP camera systems an excellent choice if you think you may need to expand your security coverage at a later date.
