security & surveillance technology
The optical performance of the lens used by the security camera is basically the same as the lens used by other photographic and camera equipment, so the lens of the security camera also follows the basic optical imaging principle.
In 2008, Axis, Bosch Security and Sony jointly initiated the establishment of a global open network video interface forum, the English name Open Network Video Interface Forum, or ONVIF for short.
The audio function has basically become the standard configuration of network cameras. Network cameras with audio functions usually provide a built-in microphone/pickup, or provide an audio input interface, users can choose to use other types or higher quality external microphone/pickup.
The quality of the image effect of the security camera is determined by the DSP processor and the image sensor sensor. How to make good use of the existing hardware resources to tune a camera with good image quality, and each manufacturer’s own video, image algorithm, and technology accumulation Closely related.

In security video and surveillance, if the time displayed by the surveillance video equipment is inaccurate, or the time between different equipment is confused, the recorder video data will lose value and be meaningless.
H.265 encoding was formulated by ISO/IEC MPEG and ITU-T in 2004. The first version of the HEVC/H.265 video compression standard was accepted as the official standard of ITU-T on April 13, 2013.
In terms of security surveillance video, cassette tapes were used in the early days, and optical discs were later used. Now mechanical hard disk storage video is still the mainstream, although SSDs and TF/SD cards are also used.
In security video surveillance, software is a very important part. This article mainly introduces the security software’s architecture, functions, problems encountered, and development trends, and also introduces some common security software.
Pixel density, in short, is the proportion of pixel size that can be recognized by human eye or machine vision (generally based on horizontal resolution pixels). The higher the camera resolution, the smaller the proportion of target picture pixels.
