Surveillance cameras sometimes suffer from environmental degradation. The following describes several environmental factors and solutions.
First, rainy days, foggy days, snow days and other places with high humidity
Shooting in this environment can cause spots and fog on the lens, affecting the quality and effect of the picture. Electrical and mechanical parts inside the equipment, if eroded by rain or moist air, can also cause malfunction and damage. The solution: There are conditions to use a professional rain cover, this cover can isolate rain, snow, fog, damp air damage to the equipment. There are no conditions, you can use parasols, which cover a large area, can block the rain and snow attacks. For fog and humid air, we can use dense materials (large plastic bags can also be) tightly wrapped the body. The lens should always pay attention to its cleanness during the shooting process, and find the dirty spots in time to clean it with deerskin, which will ensure the normal operation of the machine and the picture quality.
Second, places with heavy sand, dust, or chemically corrosive atmosphere
Sand, dust is mainly to the inside of the lens and camera. The lens cover is opened during shooting. Check the marks immediately after the shooting and clean the cover. The best choice for the body is a rain cover to prevent the sand and dust particles from entering the normal operation of the device. Chemical odor has a very serious impact on the body. It can erode electronic components, lose their inherent electrical characteristics, and damage is very serious. The consequences are difficult to predict. Rain covers or other high density materials can also be used to wrap the body. Pay attention to the working hours should not be too long, the work must be left quickly.
Third, the shooting environment temperature is too high or too low
Excessively high or low temperature has a great effect on the performance of the electronic components of the camera, including the random battery.
1. Shooting ambient temperature is too high (above 30°C)
The electrical components of the fuselage generate heat during operation, and heat dissipation is required to maintain a stable working condition. If the ambient temperature is too high, not only does it fail to dissipate heat, but it intensifies the heating of the electronic components. This will cause the components to lose their normal operating characteristics and cause distortion in the line and affect the picture quality.
Solution: The condition can be selected to blow with an electric fan to promote heat dissipation. In the field, ventilation can be selected and heat can be removed in a cool place. You can also choose to stop working for a period of time for this kind of “work and work†method. The effect is also very good.
2. The shooting environment is too cold (15% or less)
In general, it is conditional to ensure that the electronic components inside the camera work properly. Excessively high or low temperatures will affect the use of the camera. If the ambient temperature is too low, the electronic device can not reach the warm-up value, it will also affect the machine's operating characteristics. The same is true for batteries. Since the ambient temperature is too low, the internal chemical reactions and the energy release rate of the battery will also be slowed down, and the proper energy will not be fully utilized, reducing normal working hours. Although it will not cause damage to the equipment, it will affect work efficiency.
The solution: Put the "cotton jacket" insulation on the body. Unused batteries should be placed on a high temperature site or cold-proofed so that energy can be easily released.

The aluminum housing is very suitable to use in cold environment.
The gear hard is 48-52 HRC.
The motor power is high.Axis use chromium manganese titanium.
