When you've invested in professional IP cameras it is essential that you add a recorder that has enough power and bandwidth to handle the cameras in full quality. Network video recorders are designed exclusively to record using network cables. As with all of our CCTV recorders, our NVRs feature a wide range of security essentials from adjustable motion detection triggering to flexible recording schedules. They also feature an HDMI video output, allowing you to monitor the recordings in glorious HD.
NVRs are units that receive data from IP cameras and records it to an internal hard drive. This enables you to capture CCTV cameras and play the footage back later. These recorders feature a whole host of recording features and you can even access the recorder remotely over the internet to monitor the cameras and change settings.What is the difference between DVRs and NVRs?
NVRs work in virtually in the same way as DVRs, but there is one key difference. DVRs record traditional CCTV cameras that use a coaxial cable with a BNC twist-fit connection. IP cameras use network cables to transmit their data and NVRs are designed to work with these types of cameras. Cameras can be directly plugged into the NVR or they can be directed through a local network.How many channels do I need?
Channels refer to the number of individual devices the recorder can accept. Keep in mind, though, that with IP systems the maximum bandwidth of the recorder is an important consideration. Cameras with higher quality will take up more bandwidth, so although a recorder might accept 8 channels it may not have enough bandwidth to accept 4K cameras.
