First, the working conditions of infrared lamps must have good constant current power supply and good heat dissipation design. Kato (KATO) infrared lamps can be completely red-free (with 940nm to 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 a sensitivity of 850 nm than at a sensitivity of 940 nm. Therefore, the infrared light with slight red exposure at 850nm has higher efficiency, and it is also an engineering company's priority. In addition, under the premise of guaranteeing the power of the infrared lamp, reduce the heat consumption of the infrared lamp itself, adjust the angle of the infrared light, and cooperate with the best lens, so that the effective utilization rate of the infrared lamp reaches 90%.
2. During the fogging and frosting process of KATO infrared integrated camera, especially the outdoor infrared integrated camera often causes fog or frost on the protective cover glass due to seasonal changes, temperature difference between day and night, and rain and snow conditions. Causes the inability to see objects and directly affects the monitoring results. If advanced dehumidifying and defogging circuits are used, the saturated water vapor concentration in the body can be effectively controlled to achieve automatic defogging and defrosting.
Third, infrared angle infrared light is not the greater the better? Some people think that the larger the infrared light emission angle of view, the greater the scope of the lens selection, the use of wide-angle lens will not appear narrow viewing angle phenomenon. Facts have proved that there is a waste of light in infrared light with a large viewing angle and a lens with a small viewing angle. Therefore, engineers with practical experience will make the angle of view of the infrared lamp they choose to be consistent with the angle of view of the lens, so that the effect can reach the best state. In addition, the larger the emission angle of the infrared light, the better the picture effect. In some cases, if the infrared light angle is too large, the imaging will be affected. The result of doing so in a narrow corridor is that due to the large emission angle of the infrared light, the imaging of the near edge will be too bright to form a “light curtainâ€, while the center in the distance is not clear but a white fog. Therefore, the launch angle of infrared light is not only a matter of choice but also a technical problem. Different focal lengths of the lens should be selected to match the infrared angle of the launch angle, the infrared light emission angle, no matter what kind of conditions should not be greater than the lens perspective. Narrow-angle infrared light can achieve ideal wide-angle effects through reasonable selection and matching.

step Drill Bit is a drill bit that has the tip ground down to a different diameter. The transition between this ground diameter and the original diameter is either straight, to form a counterbore, or angled, to form a countersink.
The advantage to this style is that both diameters have the same flute characteristics, which keeps the bit from clogging when drilling in softer materials, such as aluminum;. Most of these bits are custom-made for each application, which makes them more expensive.
