In the current security monitoring market, several small branches have been identified, such as
surveillance cameras , infrared cameras, and so on. According to industry statistics,
infrared cameras are currently the most widely used, accounting for almost half of the entire surveillance market. Faced with such a wide market share, what are its outstanding charms? Now for everyone, what are the advantages of
infrared cameras ?
High Brightness
Obviously, the higher the brightness of the infrared camera, the farther the light is irradiated. The output power of a single LED is generally 5~15mW. Although the brightness can be increased by increasing the current, the limitation of the material itself is that The photoelectric conversion efficiency is not high, only 20% of the light, the remaining 80% is thermal energy. Therefore, while increasing the brightness, it also generates more heat energy, which is obviously not feasible for the key device CCD of the camera with strict working temperature requirements. In addition, many LED combinations use PCB boards as a carrier, and the heat dissipation performance is not good. The infrared camera 's light source, through the dozens of high-efficiency and high-power wafers, is packaged on a flat surface with a high-tech, well-configured heat-conducting device. At the same time increase its photoelectric conversion efficiency, brightness is about 100 times that of a single LED.
small volume
As mentioned earlier, the infrared camera uses a highly integrated advanced packaging technology, an infrared chip that encapsulates dozens of wafers, only the size of the nail cover. Imagine putting dozens of individual LED combinations
What is the size of the together? Small size is the most important for ease of use. If dozens of individual LED combined infrared light sources are installed on a high-speed dome camera, the effect is conceivable. long life
Infrared technology ensures a good working condition of the CCD and its lifetime is 9 times that of ordinary LED infrared cameras. The ordinary LED infrared camera places the LED light emitting tube and the camera in a cavity, and the heat of the LED tube cannot be effectively dissipated through the PCB board. The temperature problem seriously restricts the service life of the CCD. After 3 months of using ordinary LED infrared cameras, they begin to show signs of aging. The problems such as blurred pictures, whitening, lack of contrast, etc., have a direct impact on product use results, and even the entire camera is scrapped.
efficient
Determined by the characteristics of the semiconductor itself, its luminous efficiency and heat dissipation performance is a benign-ring. The better the heat dissipation performance, the lower the operating temperature and the lower the operating temperature can better guarantee the luminous efficiency. On the contrary, it is a vicious cycle of falling into efficiency. In addition, our power supply system uses its own patented high-frequency spike power supply to ensure greater efficiency.
Light uniformity
As we all know, each ordinary infrared LED has a sphere in front of it, which is a separate optical design to change the size of the spot. When multiple infrared LEDs are combined around the camera lens, the emitted light is composed of a plurality of spots overlapped, the overlapping part of the brightness will be particularly high, while also forming a circle, that is, "flashlight effect", the night vision screen effect of course It is uneven. The array infrared camera is equivalent to a large point light source. Through special optical design, the light is evenly irradiated to the monitored object, and the brightness of the middle and the surrounding of the obtained monitoring picture is the same.
In short, in the face of numerous advantages, the reason why we can stand out among many branches is really a matter of fact.
Industrial Sectional Door
Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
