The advantage of the integrated camera in the industry application is obvious, but for the mastery and perfection of its key technologies, security companies need to continuously strengthen research and development efforts. At the same time, various security companies urgently need to catch the “high-speed trains†of high-definition, IP, and intelligence, and firmly grasp the development opportunities to provide users with high-quality integrated cameras.
Application advantages of the integrated camera As a professional monitoring product, the integrated camera has been highly recognized by the security industry for its features of autofocus, beautiful appearance and so on. In terms of practicality, the integrated camera is becoming the new darling of the CCTV monitoring system with its good performance. With the declining prices of professional lenses, the cost of the integrated camera will be reduced, and the scale of its application will also continue to expand. In-depth development of video surveillance.
First, master the key technology to improve the monitoring effect From the technical perspective, the camera lens autofocus function, DSP and CCD determine the camera's performance. First of all, with respect to the autofocus function, the camera's focusing speed, accuracy, and focusing effect are of the utmost importance. This is also a bottleneck that restricts the integration of camera applications and concerns whether the camera can quickly and clearly capture images. With the security market's further enhancement of the focus requirements, integrated cameras with precise auto-focusing are increasingly favored by users and become a new direction for the development of integrated cameras. When the camera can quickly track and monitor moving objects, the accuracy and speed of focusing can be tested in real time. On the other hand, integrated cameras are mostly used for outdoor monitoring. When the camera continuously monitors the same picture, light changes can easily cause the camera to focus repeatedly. Affects the fixed focus effect. At present, the focusing problem of domestic integrated cameras cannot be solved well, so it can only be used for medium and low speed balls to reduce the problem of poor focus due to high speed rotation. Therefore, the auto focus function of domestic integrated cameras needs to be continuously improved to meet the security market demand.
The optical zoom lens of the integrated camera will determine the monitoring effect of the captured image. Lens zoom is generally achieved by changing the relative position of each lens in the lens to achieve focal length adjustment, which is a key factor in determining the lens performance of the all-in-one camera. At present, more integrated camera applications on security are 10x and 12x optical zoom lenses. It is reported that there are now 18x, 22x, 26x, 36x, and even higher optical zoom lenses. The integrated camera provides a broader application perspective.
Another core technology, DSP (Digital Signal Processing) technology, high-performance DSP can provide integrated digital cameras with powerful digital processing capabilities and high computing speeds. The high-performance integrated camera requires the DSP to have both intelligent control and digital signal processing functions in order to respond to the ever-improving application status of the camera technology, which imposes higher requirements on the performance of the DSP. The combination of the two functions has promoted the exploration of smart applications and has also improved the practical effect of integrated cameras. Nowadays, more security companies are doing DSPs, but if they want to win in the competition, only by upgrading software functions to achieve technology updates, that is, through the development of more features to achieve the key technology and performance upgrades.
For the core technology of CCD, the current security market is mainly Sony CCD, such as the use of 1/4′′SONYSuperHADIICCD to improve the camera's low-light performance. In addition, the camera's high-performance processing circuit will also affect the camera's low-light performance. For example, a The company introduced an all-in-one camera using a self-developed CDS low-noise preamplifier. Through sub-sampling, the amplifier's gain is greatly increased, creating an extra 6dB of ultra-low illumination performance, and the camera's minimum illumination in color mode. Under 0.3Lux and black and white mode up to 0.05Lux, it can help the user to achieve 24-hour monitoring.In addition, to ensure that the integrated camera can monitor high-definition picture in the night environment, the camera also has built-in day and night conversion, slow shutter Such as technology.On the slow shutter technology, the camera will further subdivide its technical level, enhance the camera's performance, can provide users with different levels of choice.
Second, play a unique advantage to expand industry applications In the rapid development of the security market today, integrated camera with its unique advantages forward steady development. Compared with ordinary cameras, the integrated camera is compact in size and simple in design. It is suitable for high-end applications and can complement beautifully decorated interiors. The intrinsic performance is more obvious. The first is the autofocus function, which makes the image very clear and enables fast and accurate real-time monitoring. Especially in the expressway monitoring, due to the fast speed of the vehicle, the phenomenon of blurred and trailing monitoring images easily occurs. The high-quality integrated camera can automatically focus the vehicle image and achieve a very good focusing effect. Monitoring and traffic management provide ideal surveillance images.
In addition, the integrated camera has a wider monitoring range and is particularly suitable for all types of large-scale monitoring sites. For the harsh outdoor environments such as high temperature, rain and snow, through the configuration of good explosion-proof, waterproof and other functions, it can solve the user's outdoor monitoring of the worries. In addition, for the special environment needs, the integrated camera also has outstanding performance. There are anti-corrosion integrated cameras for the biochemical environment, waterproof integrated cameras for the seabed, and research and development for dealing with outdoor hot weather. Integrated camera with heat dissipation function. It can be optimistically predicted that with the full play of the advantages of the integrated camera, it will bring more positive monitoring experience to various security applications.
