The integrated camera technology for security is developed from the home camera technology, eliminating the additional functions of the portable camera, display interface, and storage device of the home camera, and retaining only the camera function suitable for CCTV monitoring. General civilian machine motor life is short, when the camera time is too long will stop on their own, while the security use one machine generally requires 24 hours of non-stop shooting, the motor, camera time requirements are relatively high, single from the camera part, of course, The price is also higher than that of ordinary civilian one-piece machines. If only the low cost is required, it will affect the effective monitoring of the security system. For example, several years ago, the Wuhan shopping mall chose the civilian integrated machine to install on the security system because of the cost problem, and the result was endless. 
The key technologies of the integrated camera are lens, CCD and DSP processing modules. The lens is mainly mastered by Japanese manufacturers, such as Canon, Camputar, Avenir, etc. The one that provides the most OEM in the field of all-in-one cameras is the Canon lens. From the perspective of the CCD (the key element in the quality of the camera), suppliers are mainly Sony, Sony is CCD and civilian is the mainstream, Sony CCD is divided into two types of Super HAD and Exview, Ex view is the latest technology, commonly used The 1/4-inch size has a higher noise-to-noise ratio than Super HAD; Panasonic and Samsung each use their own CCD production machine; other Kodak and Fujifilm cameras develop professionally used CCDs. In the DSP processing chip, different manufacturers have their own characteristics, such as Sony's DSP chip in the relatively good color reproduction, and Canon, Nikon's DSP in the light capture mode and focus better. 
At present, all Chinese-made machines use imported movements, so there is no difference in image and picture quality compared with foreign products. Therefore, the technical points of domestic products are considered in terms of product durability, because the domestic products in the machine's motor And on the transmission device is its own research and development, the heat resistance of the motor and transmission directly affects the stability and durability of the one machine. The motor used in the integrated machine has a synchronous motor and a DC motor. The temperature of the synchronous motor rises quickly and the service life is relatively short. However, the cost of the DC motor is too high, so the market is still mainly based on a synchronous motor.
The key technology of the integrated camera
For the integrated camera, there have been several different understandings, including the dome-type all-in-one machine, the fast ball-type one machine, the integrated camera with the PTZ, and the built-in camera. Strictly speaking, fast dome cameras, dome cameras, and general all-in-one cameras are not a concept, but the camera technology used is the same, so it will generally be classified as an integrated category. Nowadays, what is commonly referred to as an integrated camera should specifically refer to a camera built-in, autofocusing integrated camera
