DVR and nvr
DVRs
A DVR is device that stores tv shows and movies from the television provider to give you on-demand access. You can record multiple shows at once while watching another show and also set the device to record the show ahead of time. You also don't need WiFi so you don't have to worry about the internet suddenly stopping in the middle of a recording! DVR systems work with analog cameras. These cameras stream raw video footage to recorders by using coaxial cables and the recorder processes the video. Wired cameras are a great idea if you have an inconsistent Wi-Fi signal or a large property taking up alot of area. Wireless signals dont extend far. The most a wireless signal would extent would be around 300 feet if there is not wall or object blocking the signal. So in short a wired system provides a more reliable signal.
NVRs
NVR stands for Network Video Recorder. NVR systems record and store video footage directly from the network. NVRs work with IP cameras which are more advanced than their counterparts, analog cameras. IP cameras can process video and audio data using either an ethernet cable or wirelessly via an existing WiFi network.
Once the video is processed, both DVR and NVR systems work the same. After connecting to a smartphone or any other viewing device, you can easily access and view your video footage.
DVR Pros: Less expensive than NVR, easier to use and install typically, DVR systems are still improving
DVR Cons: Captures frames at a lower rate than NVR systems and has lower image quality, more cables, requires its own power source, 1 camera cannot cover the same area as 1 IP camera, cannot record audio.
NVR Pros: Better System Quality, can record video and audio while DVR only records video, Better image quality, can be wired or wireless while DVR has to be wired, can use only 1 cable for visual, audio, and power, NVR can be used to view faces, license plates and the like because of the high resolution
NVR Cons: The software is can be more complicated than the DVR systems, the cost can be more expensive than DVR systems
