Now that we’ve learned about NVR and DVR systems and their differences, let’s explore the advantages and disadvantages of each to help you determine which one is best suited for you.
Network video recorders (NVRs) are now mainstream with more camera manufacturers and homeowners choosing them over digital video recorders (DVRs). Here are some reasons why:
1. NVR CCTV records higher quality videos
NVRs pair with IP cameras, with resolutions ranging from 2MP to 12MP or higher. This resolution is far superior to that of analog cameras in a DVR security system. Advanced resolution capabilities make NVRs a clear winner for identifying intruders’ faces and license plate numbers.
While some security brands have produced 4K DVR security camera systems to improve clarity, the DVR system loses its price edge due to the expensive video processor chips required for high-quality images.
2. NVR security systems are easy to wire
NVR cabling work is simplified. WiFi NVR wirelessly visits cameras through the network, removing the need to run wires to the network video recorder. Power-over-Ethernet (PoE) NVRs provide both power and network to cameras over a single Ethernet cable. Long-distance wiring can be done with a PoE switch.
In contrast, DVR systems require exact point-to-point connections between the cameras and digital network recorder, and analog cameras necessitate wires for both power and data transmission.
3. NVR recorders are flexible in placement
Because NVRs use IP-network cameras, they can be placed virtually anywhere with network availability. In contrast, DVR CCTVs are limited by coax cables with a maximum 300ft transmission distance.
4. NVR systems are easy to use and configure
NVR systems may seem complex, but P2P NVR security cameras make configuration a breeze.
With Zosi Smart App, for example, IP cameras automatically show up on the LAN network device list. Add cameras to the client with your password, and the setup is complete. Complex port forwarding and configuration are not required. You can access cameras via phone by entering the unique ID number (UID) of the network video recorder and its password in the NVR camera app.
Editor’s Note: You can view a live stream and recording of cameras without a network by following this guide to connect your NVR camera system to a monitor. You can view and replay recordings immediately without connecting to a router.
