Notes on installation of dry powder ball press :
3. Ground loop circuit: Even if the equipment is effectively grounded, there are differences in the zero potential between the dome camera and the center equipment, and there is an imbalance in the power load, which will still cause a ground potential difference. This potential difference generates a current through a closed loop formed by the coaxial cable, causing interference, thereby affecting the normal transmission of the video signal, and usually manifests as horizontal clutter in the middle of the image. The most effective way to solve the problem of the ground loop is to add a ground loop isolator in the video transmission. At present, most indoor / outdoor dome video signals are still transmitted by coaxial cables, and some domes are far away from the center equipment, which makes it easier to form ground loops. If the optical transceiver is used for signal transmission, the influence of the ground loop can be avoided more effectively.
4. Waterproof: Outdoor dome installation must be waterproofed. For suspended installation, there is a gap between the dome and the bracket. In case of rain or snow, water will seep into the interior along the gap and cause harm. Therefore, waterproof sealing measures should be taken during installation to prevent rainwater from entering the dome mounting bracket from the screw interface. The original bracket is recommended. The original bracket fully considers the waterproof problem, such as the tilting design makes the dome screw end slightly higher. Even if the water enters the bracket, it will only flow back into the column, and will not flow into the ball machine. Therefore, if users make their own brackets, they should fully consider the waterproof factor. Why are there water drops in the stand? Generally, during the day, the temperature is high, and the water vapor in the pole enters the support. When the temperature decreases at night, water vapor will condense into water droplets and condense along the wall of the support. When the stand is not tilted or tilted in the opposite direction, water droplets will flow into the dome along the wall, causing harm. In order to reduce water vapor from entering the bracket, the joint between the bracket and the pole can be sealed with plasticine or silicone.
5. Heat dissipation: The heat dissipation problem of the dome must also be considered. Some brands of dome cameras on the market do not have outdoor models, so they cannot be directly used outdoors. They must be equipped with accessories such as outdoor shields. The Pelco outdoor dome camera includes standard elements such as a sunshade, heater, and dual cooling fan, making it suitable for outdoor harsh or extreme temperature differences.
