In winter, not only low temperature is a factor that affects infrared cameras, but also the sealing performance of each component is a significant challenge. Low temperature will impact the performance of electronic components, such as decreased battery life, electro-optical system malfunctions, etc. Low temperature, rain or snow will also cause internal fogging and condensation, affecting the lens and the inside of the body. So you need to pay attention to the following points: 1. Cold weather protection Before use, make sure the battery is fully charged to maintain normal voltage. Facilitate battery preheating to enhance chemical activity internally, ensuring the normal functioning of all components. Avoid voltage dips and prevent damage to fragile plastic components in low-temperature environments. Prevent safety hazards such as freezing of components. 2. Snow and Rain Protection Rain, snow and icing are also serious problems. Be sure to promptly clean up any ice or snow covering the camera's surface. If liquid is observed on the camera's surface, wipe it clean to prevent potential freezing during use. After the ice and snow melt, moisture in the gaps will more easily enter the interior of the camera. When clearing, we can use various tools, but try to avoid using substances with chemical reagents, as they may corrode internal circuit boards.  If fogging occurs inside the lens, you can accelerate the dissipation of water vapor in the lens by turning on and preheating. 3. Static electricity and precautions Winter clothing tends to be thick, contributing to a higher likelihood of static electricity buildup. And static electricity is the most easily ignored topic in winter. Given that static electricity can lead to poor contact or even short circuits, it is essential to power off the camera when operating. Additionally, it is advisable to touch a metal object before operating to avoid the risks associated with static electricity. 4. Dryness and moisture-proof precautions In addition to moisture protection, it is crucial to prevent excessive dryness during winter. Overly dry environments will also produce certain hazards, especially to lens components. In severe cases, it can cause the coating to crack and peel off, and easily lead to cracks in the rubber of the camera.
