NVR or DVR

Do you want a Network Video Recorder (NVR) system or a Digital Video Recorder (DVR) system for video surveillance? Both record videos but NVR can record audio as well. While NVR works with IP cameras and directly stores videos, DVR works with analog cameras and streams videos to recorders before processing. When compared with DVR, you enjoy more advanced technology with NVR and so it is more expensive. Let’s look at NVR more closely. It is a computer system with video management and recording software. With NVR, you can set up a recording schedule for your IP camera and take advantage of the alarm function called “motion detection’ to start a recording. If you want to pick a good NVR, you have to check if it has a highly reliable and redundant RAID HDD system. That’s how you make sure your data is safely stored. Sometimes, you need specific video output functions like ‘evidence shot’ to capture HD still images to provide evidence. An NVR with 4K recording and playback capability is ideal as well.

Due to the COVID-19 pandemic, body temperature detection is very important these days. Touch-free terminals, bullet cameras, and walk-through arches are some of the devices that provide body temperature detection. There are many options in the market, you can look for ones that have short response times and high accuracy.
