What is an NVR?
NVR stands for Network Video Recorder. It records videos while being relayed on a network cable. This system works with IP cameras via LAN or through an internet network.
NVR works like a computer program. The IP camera does the encoding and processing of the videos.
What is a DVR?
DVR is an acronym for Digital Video Recorder. It is a device that works similar to a video encoder. It utilizes an analog CCTV camera and obtains an H.264 compressed analog video signal.
DVRs are more stable compared to NVR. However, it is not compatible with some latest CCTV cameras models. Also, the quality of the video is poor.
If you prefer high-resolution videos and a video surveillance system that is easy to set up, your best bet is NVR.
Installing and Setting up and NVR
If NVR is your choice, here are some tips to guide you on how to install and set up the surveillance system.
Before anything else, there are two types of NVR; these are the PoE (Power over Ethernet) and Non-PoE (has no Ethernet ports on the back panel).
PoE models are only compatible with cameras that feature PoE specifications. This version has to be powered by plugging ti to the NVRs PoE ports.
Meanwhile, a non-POE uses no ports for cameras to connect. However, it can add cameras with scan function and connect to the network.
How to Setup a PoE NVR
- Turn on the NVR. Then, connect the Ethernet cable from the router to the back panel of the NVR.
- Connect one of the PoE ports to the NVR and camera using an Ethernet cable.
- Connect NVR to a monitor by using a VGA or HDMI cable.
- Setup the software once the NVR is connected and turned on. Log into your NVR using your NVR login credentials.
- Go to the main menu and look for the settings then click the camera option.
- Do a device search to view the IP address. Once it appears click the IP address and click the add button.
- Go to the manual add button, and add the device. The audio connection mode will appear. Choose the default setup (TCP).
How to Setup a Non-PoE NVR
- Follow the same hardware setup for PoE NVR.
- Connect a camera to another router port but on the same network as the NVR.
- Connect the NVR to a monitor using VGA and HDMI
- Follow all the software setup step of PoE that is indicated above.
