How does security surveillance camera add face recognition?
Security surveillance cameras have been in our lives for more than 10 years, so if you have installed some different types of cameras it is a very common thing. CCTV (analog camera) is a security surveillance camera that is used earlier and is still popular today. It is also called AHD (Analog HD) camera.
A typical CCTV system consists of a DVR (Digital Video Recorder) and many analog cameras. Take a look at the back of your VCR (if you can't tell if it's a DVR or an NVR, we'll discuss it further later), and many coaxial cables are plugged into the DVR to transmit analog signals.
So, you have an analog camera. The image quality of the analog camera is not reliable for face recognition. In this case, the most practical and cost-effective way to implement face recognition is to install a face recognition camera (a face recognition camera is a digital IP camera). In recent years, digital security cameras or IP cameras (IPC) have become more and more popular in the market, and the resolution has also rapidly increased to 720p, 1080p, 4K. The digital version of the hard disk recorder is called the NVR, which is a network hard disk recorder.
The digital camera encodes the video through the H.264/H.264 codec and transmits the video stream over an IP network, unlike the coaxial cable used in analog cameras. When you check the back of the DVR and find it is an NVR, congratulations, you have installed a digital camera. Most word cameras are compatible with the ONVIF protocol.
This protocol is used to ensure that digital cameras from different vendors can be connected to NVRs from different vendors. If your digital camera supports the ONVIF protocol, congratulations again, you can use the pcDuino face recognition box to capture faces from existing digital cameras for face recognition.
The caveat is that although your digital camera can now be used to extract faces, it is still important to install it in the ideal location for face recognition. The face pose, that is, the relative angle between the face and the camera has an important influence on face recognition. A big gesture is not conducive to face recognition.
