NVR Distributor in Dubai
Network Video Recorder (NVR ) is used with IP cameras over a local IP network with a network attached storage device. Live video can be accessed and managed over the internet using a computer or Smartphone. One benefit includes the use of better cameras that provide enhanced video imaging.NVRs serve as the central hub for recording in an IP security camera system. Unlike traditional DVRs, there is no digital processing done at the NVR — the processing is done at the IP camera and then sent via network cable (ethernet cable) to the NVR. Each IP camera is like a computer on a local area network (LAN), each with its own IP address and connection to an NVR. This aspect of NVR and IP camera systems is very useful if you have an existing LAN network — connections don’t have to run through the entire length to an NVR; they simply have to connect into a LAN network. The NVR records the digital video signal and enables remote access to each IP camera live feed. As with DVRs, the number of cameras an NVR can handle is defined by the number of channels it has, from 4 channels (4 cameras) up to 16 channels (16 channels) or more. NVRs have the ability to power their IP cameras through use of a Power-Over-Ethernet or POE technology. Not all NVRs or IP cameras are equipped for POE, so that’s something to keep in mind when reviewing your options.
Exactly like DVR storage, NVRs use hard drives to store your video feed. As opposed to DVRs, however, NVRs are capable of recording at higher resolutions; NVRs can record up to resolutions of 1920 x 1080 (or 2.1MP or 1080p). Again, higher resolution implies requiring more space on a hard drive, but most NVRs come with larger hard drives to accommodate the higher recording resolution. NVRs offer great flexibility with installations and higher recording resolution, but keep in mind that a strong, reliable local network is required for maximum operability. If you run multiple systems (like IP phones or POS systems) on your LAN, an IP camera system may strain your overall network performance.
The NVR connects via your internet and connects with your cameras in the same fashion as opposed to having a direct connection from the camera to the box. This proves to be convenient for many because camera placement never becomes an issue. You have the freedom to move your camera to just about anywhere as long as it falls within range of your network. Also, if you have multiple places across the country or state that you’d like to monitor without having to pay for separate individual systems, the NVR allows users to simply connect the cameras onto your view as long as that camera has an internet connection at its location.
