Infrared integrated cameras have outstanding advantages such as long night vision distance, strong concealment, and stable performance among surveillance cameras, so they occupy most of the market in surveillance projects. The infrared integrated camera with excellent performance has the following performance:

1. The working conditions of infrared lamps must have good constant current power supply and good heat dissipation design. KATO infrared lamps can be completely free of red exposure (using 940nm ~ 950nm wavelength infrared tube) or only weak red exposure. The shorter the wavelength, the stronger the red exposure and the higher the infrared sensitivity. Practice has proved that the infrared integrated camera is 10 times better at 850nm wavelength sensitivity than at 940nm wavelength sensitivity. Therefore, the infrared lamp with a slight red exposure at 850nm has higher efficiency, which is also a priority for engineering companies. In addition, on the premise of ensuring the power of the infrared lamp, the infrared lamp's own heat consumption is reduced, the infrared light angle is adjusted, and the best lens is used, so that the effective utilization rate of the infrared lamp reaches 90%.

2. During the fogging and frosting process of the KATO infrared integrated camera, especially the outdoor infrared integrated camera often forms fog or frost on the protective cover glass due to reasons such as seasonal changes, day-night temperature difference and rain and snow environment, etc. , Resulting in the inability to see clearly, directly affecting the monitoring effect. If the advanced dehumidification and defogging circuit is adopted, the saturation water vapor concentration in the body can be effectively controlled to achieve automatic defogging and defrosting.

3. The angle of infrared light Is the infrared light angle as large as possible? Some people think that the larger the angle of view of the infrared lamp emission, the greater the choice of the lens, the narrow angle of view will not appear when the wide-angle lens is used. Facts have proved that there is a waste of light when infrared lamps with large viewing angles and lenses with small viewing angles are used. Therefore, the engineering firm with practical experience must make the angle of view of the infrared lamp selected by itself match the angle of view of the lens, so as to achieve the best effect. Furthermore, it is not that the greater the emission angle of the infrared lamp, the better the picture effect. In some cases, if the angle of the infrared lamp is too large, it will also affect the imaging. The result of doing this in a long and narrow corridor is that the infrared lamp's emission angle is too large, and the imaging at the near edge will be too bright to form a "light curtain", while the far center is not clear, just a white fog. Therefore, the emission angle of the infrared lamp is both a selection issue and a technical issue. Lenses with different focal lengths should choose infrared lamps with suitable emission angles. The emission angle of infrared lamps should not be greater than the angle of view of the lens under any conditions. The infrared lamp with narrow viewing angle can obtain the ideal wide-angle effect through reasonable selection and matching.

4. The sensitivity of KATO infrared integrated camera The camera sensitivity is the core part of infrared integrated night vision monitoring. The better the sensitivity, the stronger the ability to sense infrared. In practice, the infrared integrated camera within 50 meters should use an illumination of 0.5 Lux, and the 100 meter range should use an illumination of 0.01 Lux. However, the higher the sensitivity, the higher the price of the camera.

5. The constant temperature of the KATO infrared integrated camera and the fully enclosed KATO infrared integrated camera, due to the configuration of the infrared lamp with large heat generation, the front temperature inside the machine is high during the entire working period If the heat dissipation is not uniform, it will affect the normal operation of other components in the machine, so consider the case with forced heat dissipation and cooling when selecting the model. The so-called totally closed, without leaving any pores, to prevent the entry of dust, moisture and corrosive gases and damage the machine parts.
