First, low lighting significantly, showing clear
Anyone who has done security knows that many years ago, the DVR card's compression chip was very hot, and some DVRs, in order to achieve better heat dissipation, manufacturers attached heat sinks to the chip, and even prepared a small fan to reduce Temperature, otherwise the machine will crash because of heat. Not only the DVR, but also the camera, the temperature can not be too high.
As digital HD is widely recognized by the industry as a development trend, millions of high-definition solution providers have recently emerged in a hurry to battle high-definition, but we have found that there are many chip solution providers that use the compression chip on the DVR to use the camera. As we all know, compared with the camera DVR's machine shell is very large, easy to heat, and some DVR internal fan, even if the DVR compression chip power consumption is a little larger, may not affect the DVR's stable work, but if it is hard To put the compressed chip used in the DVR into a small camera, the heat is difficult to disperse, and the stability of the machine is difficult to guarantee, especially to the hot summer, the outdoor sun exposure at noon, the stability is more worrying .
As we all know, the most used security cameras are infrared cameras. The original machine has a lot of heat, and the infrared lamps are even hotter. In addition, it is worth mentioning that the current low-illuminance camera of millions of HD cameras in China is not only poor in the ability to sense visible light, but also weak in the ability to sense invisible light. Therefore, in order to achieve the desired infrared effect, it is forbidden to Without increasing the current and the number of infrared lamps, the originally very hot camera is heated and reheated.
Second, the quality of photosensitive chips and technical solutions directly affect the quality of the product
Because of the adoption of low-power digital camera movements and the use of the latest low-illuminance CMOS technology, the ability to sense infrared light is strong, so the machine generates little heat and enhances long-term stability. Choose the lowest power consumption low-power infrared lamp products and the lowest power chip and low illumination technology on the market, and combine the infrared lamp angle with the lens angle, so that the use of infrared lamps is greatly improved, so no need to Many infrared lights can achieve a good night vision effect.
In order to reduce the heat output of the camera's power supply during operation, the power supply of the camera has been specifically moved outwards, and the world's lowest power POE power supply technology has been used, making all the wave particles reach the lowest power consumption and the lowest heat, improving product life. .
When choosing a shell, instead of selecting a beautiful shell, it focuses on the principles of thermodynamics and heat transfer to make the heat dissipation and thermal conductivity of the camera network board and chip the best. This also makes the camera of Ternos not need to be large. The shell achieves good heat dissipation and improves product stability and service life.
Third, the system's integration in supporting programs
Due to the early days of digital high-definition, there was no internationally unified front-end and back-end communication standard as in the analog era. Therefore, HD manufacturers must not only provide customers with a series of cameras, such as general bolt hemispheres, infrared cameras, ultra-low illumination cameras, and wide dynamics. A series of cameras, such as the HD Speed ​​Dome, also provide back-end HD decoders, hybrid DVRs, pure digital PDVR (or NVR) and a series of back-end devices.
The incomplete series of high-definition front-end and back-end devices has a negative impact: It is difficult to apply to large and medium-sized projects because the larger the project, the more types of cameras and ancillary equipment are required. The side reflects the R&D strength of HD manufacturers, many so-called high-definition manufacturers, lack of technology research and development, naturally lacks the ability to distinguish the quality of the program, buy two-stream program processing and assembly of high-definition cameras, if you purchase this camera, once the product meets the actual application site Special circumstances and abnormalities, after-sales service will become a problem.
Fourth, product maturity and stability
According to the product is divided into: million HD gun, million HD hemisphere, million HD IR gun, million HD IR hemisphere, million HD high-speed ball, million HD high-speed infrared ball, million HD elevator dedicated camera, one hundred Million HD wide dynamic camera, Million HD low light camera, Million HD zoom machine, Million HD zoom machine movement, Million HD NVR, Million HD network storage host, Large management platform, Million HD decoder , Million HD module mixed acquisition card, Million HD system card, POE power supply switch, Million HD dedicated fiber optic transceivers, million HD high-definition cable, and other full-series million HD products. Million HD full range of products, to meet the different needs of different customers, different industries, there is always a suitable for you.
