If you are searching for a security camera, you need to see if a Network Video Recorder (NVR) system or a Digital Video Recorder (DVR) system suits you better. Both NVR and DVR can record videos. The difference between them is that NVR (working with IP cameras) can directly record and store videos while DVR (working with analog cameras) cannot. Now let’s look at the pros and cons of each video surveillance system. Concerning the pros of NVR, it gives better image quality, only needs one cable for everything, and can record audio along with a video. As for a DVR, it is less expensive, and easier to set up and operate.
With coronavirus around, body temperature detection becomes more important than ever, hence the abundance of body temperature detection systems present in establishments. From bullet and turret cameras to touch-free terminals to walk-through arches, devices designed for body temperature detection come in all shapes and sizes. And only the ones that offer short response times and high accuracy stand out.
Then how about hand-held thermometers? Don’t they work too? Well, they work. But they are too inefficient to be used in a fast-paced society. Usually, for other devices, the body temperature of thirty or more people can be measured simultaneously in real-time. For hand-held ones, however, measurements can be taken only one person at a time. Imagine waiting in a long queue for body temperature detection every time you try to enter an establishment, isn’t that a nightmare?
