The pursuit of high definition CCTV security focuses on two aspects: one is the lower illuminance and the other is higher definition.
The low illuminance is mainly depended on the camera, and there are star-light cameras with 2MP, 3MP and 5MP resolution ratio available on the market. Even under poor light environment, star-light cameras are still able to produce remarkable imaging effect. As deduction in cost, these products will gradually gain their popularity.
As for definition, currently the 720P and 1080P HD video cameras are popular, and the ultra HD products with 4K and 8K resolution have emerged as well. However, these ultra HD products place significant pressure on the security camera, transmission and back-end equipment characteristic by bringing huge data flow. At the same time, with the limitation on the target surface of ultra HD camera sensor, the sensing area for a single pixel decreases as the number of pixel increases. As the result, the colorized low-illuminance photos of ultra HD camera are hardly satisfying. Fortunately, the H.265 compression technique is invented and it can produce the same quality works with half compression rate compared with the current H.264 technique, hence wiping out the key obstacle for the ultra HD monitoring system. So the cameras, back-end NVR, screens and platform that support H.265 technique will be gradually applied in HD and ultra HD security system, bring better visual experience to users.
