What is an integrated camera

The integrated camera has always had several different understandings, including the dome-type all-in-one machine, the fast ball-type one machine, the integrated camera with the pan tilt, 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. The so-called integrated camera now refers specifically to an integrated camera that is built into the lens and can be automatically focused.

Integrated Camera Applications and Types Integrated cameras are used in many government projects, high-end high-rise buildings, shopping malls, schools, hotels, and hotel lobbies. There are also dust-proof cameras that are suitable for places with high environmental requirements, such as hospital operating rooms. Type and explosion-proof products with low temperature and no spark. Other professional integrated cameras, such as military, aviation, polar, seabed, and biochemical environments, have different special functions such as anti-high pressure, anti-corrosion, anti-vibration, etc. because of their different uses.

There are many types of integrated cameras, and the current market players can be divided into color high-resolution type and day/night conversion type, with the maximum zoom ratio of 16, 18, 20, 22 times, and the other 6 times and 10 times less. In general, the trend of the all-in-one machine is that the illumination is getting lower and lower, and the multiple is getting higher and higher. For example, there are now 35 times the long focal length lens, black and white minimum illumination 0.0005LUX.

Advantages of the integrated camera The integrated camera is based on the technology of the home camera. Compared with the traditional camera, the integrated camera is compact and beautiful. It has advantages in installation and is convenient. Its power supply, video, and control signals all have direct connectors. , unlike traditional video cameras with troublesome connection. All-in-one imaging system (lens), CCD, and DSP technology patents have been mastered by internationally renowned manufacturers. Compared to traditional cameras, the quality of all-in-one cameras can be well controlled. At the same time, integrated cameras have a wide range of monitoring and cost-effectiveness. The traditional camera positioning system is not flexible enough and requires manual focusing. The biggest advantage of the integrated camera is that it has an auto-focus function.

Good waterproof function is also one of the characteristics of the integrated camera. The outdoor camera of the integrated camera has waterproof function. However, the traditional camera needs to be used in conjunction with the head and the protective cover to achieve the waterproof function. There are now more submersible integrated cameras developed specifically for underwater operations, such as underwater cameras used in swimming pools in Olympic venues.

For the service life of the integrated camera, some manufacturers believe that the integrated camera lens is tightly closed, is less affected by the external environment than traditional cameras, and has a longer service life; in addition, some manufacturers believe that the camera itself does not have a mechanical device. After the lens is broken, it can be replaced again, it will not affect the camera's own camera performance, and the integrated camera lens is built-in, there is wear on the camera body in the zooming process of the lens, so compared to the life of the integrated camera than the traditional camera Short; but the common point is that the service life of the integrated camera is related to the manufacturer's technology. Regardless of the integrated machine or the traditional machine, the service life is affected by the camera's own components and manufacturing processes (such as waterproof, dustproof, and moisture-proof properties). The influence of the installation environment (such as voltage, temperature, humidity, etc.). Generally speaking, a good product has a service life of 5-10 years. Actually there will be new alternative products after 5-10 years. Therefore, as long as it is not a product with too low a technology, the service life will not be very large. problem.

Current disadvantages of integrated cameras The price of integrated cameras is too high Although the market for integrated cameras has grown rapidly, it is not yet possible to completely replace the traditional machine market. First, the black-and-white camera market, which is widely used in the Mainland and small-scale projects, cannot be completely replaced by a general color camera. The all-in-one machine cannot reduce its cost even lower than that of a black and white camera. In the security industry, traditional cameras are still the mainstream. In theory, the lens used in the integrated camera reduces a lot of peripheral equipment, the price should be lower than the ordinary lens, but because of the small size, high demand, the price is rather high, Xinyuan Sheng, general manager He Wei said, only when the integration When the price of the camera lens is reduced to coincide with the ordinary lens, it may completely replace the traditional color camera market (except for special applications).

Integrated camera protocol is not unified The technical bottleneck of the integrated camera development is how the lens supplier cooperates with the camera manufacturer for development. At present, there is a lack of common protocols and standards between lens manufacturers and camera manufacturers. Lens manufacturers are special suppliers to camera manufacturers. Lens manufacturers are manufacturers of integrated camera manufacturers for integrated camera lens, get another camera manufacturer The integrated camera may not apply. Currently, the application scale of integrated cameras is not very large, so the number of lenses for special offers will inevitably not be very large, so the price of integrated camera lenses will remain high, which will lead to high cost of integrated cameras. In turn, it affects the development and application of the market. From the perspective of manufacturers' interests, all manufacturers certainly hope to keep their respective technologies confidential, but for the technological advancement of the entire industry, there is a common platform of agreements and standards that will greatly promote the development of integrated camera technology. .

Integrated Cameras In addition to the ultra-low illumination and wide dynamics, it is difficult to achieve the same advantages as traditional cameras in special applications. In many special locations, integrated cameras cannot be used. The integrated camera (including all-in-one with pan/tilt) is suitable for indoor/outdoor applications where the image quality is generally required, the monitoring scope is small, and the project investment is small; the dome camera is suitable for indoor concealed installation and the image quality requirements Not high, with beautiful, hidden installation as the main purpose of the occasion; smart ball machine suitable for indoor / outdoor environment, pay more attention to the overall use of camera equipment, ease of use and beautiful concealed installation, image quality requirements in general; other special-shaped camera (smoke Sense, pinhole, UFO, etc.)

Suitable for places where the indoor environment has special installation requirements. Traditional cameras have their own advantages, such as traditional camera focusing and zoom synchronization, can track moving objects, can be used for highway vehicle tracking, and integrated camera is automatic focusing, when the camera automatically zoom, focus needs to go through a regulation time Focusing is always slower than zooming, so when you monitor a high-speed moving object, the multiple changes, and you can't determine the focus. In theory, the integrated camera technology is higher than the traditional camera. The integrated camera can do the traditional camera. When the integrated camera motor speed is fast enough, the time difference between the focus speed and the zoom speed can be reduced to enough hours. Do tracking and monitoring of moving objects. In terms of current technology, the all-in-one machine has not been in the market for a long time. For the time being, there has been no good product tracking and shooting for fast moving objects.

In addition, traditional cameras can achieve ultra-long-distance monitoring, such as the border, dozens of kilometers of coastline monitoring, this monitor lens is very high in multiples, the volume is very large, if such a lens to be built, then built-in integrated camera It can be called a "jumbo".

Comparison of the advantages and disadvantages of the integrated camera For the comparison of the advantages and disadvantages of the integrated camera performance, manufacturers generally believe that the brand should be focused on the actual use of the effect. Measuring the performance of an all-in-one machine depends on its optical multiple, strong light suppression function, automatic white balance function, signal to noise ratio, etc., but more importantly, it depends on its actual effect, because many OEM brands look at the performance parameters above and international There is no big difference in the brand, but the actual application of the effect of the gap is very large, just look at the parameters do not necessarily reflect the true performance of the product, which is also a bad situation in the field of domestic security monitoring.

Compared with the advantages and disadvantages of integrated cameras, from the optical point of view, we must pay attention to its imaging range, light response (color, sharpness), lens group design. The core technology of the integrated camera focuses on the auto focus function of the lens. A good product can focus on one shot at a time. However, a product with a poor quality will reciprocate back and forth when it is focused. It takes three or four shots to focus, or It cannot be fully focused at certain distances within the focus range. Compared with the advantages and disadvantages of integrated camera performance, manufacturers with similar grades may not have much difference in product specifications and parameters. Now they have also developed day-night conversion and low-illuminance products, and the zoom ratio has also reached 25, 27 times, so the product is good or bad. Still should pay attention to the brand, in general, the brand good product, its quality is more guaranteed.

Integrated camera technology advances Security camera integration technology has evolved from home camera technology, eliminating the added functionality of a home camera's portable devices, display interfaces, and storage devices, and retaining only camera functions that are suitable for CCTV surveillance. General civilian machine motor life is short, when the camera time is too long will stop on its 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 concerned, it will affect the effective monitoring of the security system.

The key technology of the integrated camera lens integrated camera is the lens, CCD and DSP processing module. 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 cameras), suppliers are mainly Sony, Sony is CCD and civilian is the mainstream, Sony CCD is divided into Super HAD and Exview two types, of which Exview commonly used 1/4 inch size , S/N ratio is higher than Super HAD; Panasonic and Samsung each use their own CCD production machine; other Kodak, Fujitsu develops professional CCD. 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.

The integrated camera movement currently uses imported movements for integrated cameras in China. Therefore, there is no difference in image and picture quality from foreign products. Therefore, the technical considerations of domestic products are focused on the durability of the products, because domestic The product is developed on the motor and transmission of the integrated camera. The heat resistance of the motor and the transmission directly affects the stability and durability of the integrated machine. The motor used in the integrated camera has a synchronous motor and a DC motor. The temperature of the synchronous motor rises rapidly and the service life is relatively short. However, the cost of the DC motor is too high, and thus the integrated camera market is still mainly based on synchronous motors.

The future development trend of the integrated camera Network and automatic tracking function is the development direction The development direction of the integrated camera technology can be seen from several aspects:

Integrated camera imaging technology - the integrated camera has a higher lens magnification and a wider shooting distance;

The integrated camera has a higher number of pixels - improving image clarity;

The practicality of the integrated camera - the developer's thinking, understanding of the market, determines whether the product has practical value.

New technologies for integrating the integrated camera include day and night automatic conversion, image hiding, image rollover, image alarm (alarm for specific detection area), and more.

Like the ordinary camera, the integrated camera has new progress in digitization and network functions, mainly digital processing technology. The IP processing module is embedded in the integrated machine and has network function; the other is target locking and automatic tracking. In theory, the automatic tracking function can be well implemented. However, in practical applications, the multi-target tracking device can only automatically select the largest target to lock. Network functions and automatic tracking functions are also the directions for the development of future cameras (including integrated cameras and ordinary cameras).

The integrated camera now refers specifically to cameras that can be automatically focused and built into the camera. Its technology has evolved from home camera technology. Compared with conventional cameras, the integrated camera is compact and beautiful, easy to install and use, and has a wide range of monitoring and cost-effectiveness. Gao, after being successfully applied to the video display platform of the education industry, is forming a new round of impact on the security industry monitoring system.
