Spherical camera installation precautions The engineering company often encounters many problems when installing the ball machine. The following points should be noted when installing the ball machine: Note 1: Power supply In order to ensure the normal operation of the dome, the power supply should not be lower than the nominal value of the input voltage of the dome. When the nominal value is 24VAC, the voltage fluctuation should not exceed ±25%. When the mains voltage fluctuation exceeds the range of +5% to -10%, an AC voltage regulator should be provided. The UPS can be installed to provide an uninterrupted and stable power supply. Note 2: Grounding The grounding of the ball machine is mainly divided into the grounding of the casing and the internal electrical grounding. The grounding of the outer casing is mainly used to prevent static electricity accumulation, electrical leakage, etc., and the outdoor ball machine is also specially equipped with external lightning protection measures. Note 3: Ground loop Even if the equipment is effectively grounded, there is a difference in the zero potential between the ball machine and the central device, and the power load is unbalanced, which will still cause the ground potential difference, thus affecting the normal transmission of the video signal, usually in the horizontal direction of the image. Clutter. The most effective way to solve the ground loop problem is to add a ground ring isolator to the video transmission. Note 4: Waterproof Outdoor dome installation must be waterproofed. For suspension installation, there is a gap between the dome and the bracket. In case of rain or snow, water will penetrate into the interior along the gap and cause harm. Therefore, waterproof sealing measures should be taken during installation to prevent rainwater from entering from the screw interface. In order to reduce the entry of water vapor into the bracket, the joint between the bracket and the pole can be sealed with plasticine or silica gel. Note 5: Cooling The heat dissipation problem of the ball machine must also be considered. Some branded domes on the market do not have outdoor models, so they cannot be used outdoors. They must be equipped with accessories such as outdoor shields to adapt to outdoor harsh or extreme temperature differences.

In video surveillance cameras, dome cameras are the perfect fit among many cameras, both in terms of appearance, type and function. The perfect appearance of the lines, but also the function of infrared, low illumination, wide dynamic, and in the era of popular webcam, ball monitoring accounts for the majority of the proportion. Spherical cameras can be seen everywhere in streets, intersections, subways, campuses, etc. With its popularity, the problems encountered in the installation of dome cameras have increased, providing a common spherical camera troubleshooting method.
