Network Video Recorder (NVR) security cameras are a popular part of wireless surveillance systems. These cameras contain only one wire (that is the power cable). It saves the users from the hassle of wiring and makes the installation and usage very comfortable.
Network video recorder can be described as a networking camera that is capable of recording images as well as live videos. It can also manage an entire IP or digital video system. The best part about network video recorders is that they can be customized according to your requirements.
