Explosion-proof ball machine is different from general camera in installation and construction details

Explosion-proof ball machine is the abbreviation of explosion-proof high-speed dome camera. Some people also call it a ball-type explosion-proof camera, explosion-proof high-speed ball, etc. This is an explosion-proof video surveillance product that integrates camera, pan/tilt and explosion-proof casing.

From the long-term perspective of development, the network of high-definition, intelligent and rapid technology integration is the mainstream development trend of future development. In the future, the development of the ball machine will realize the interconnection and intercommunication between multiple manufacturers and multiple platforms by supporting the GB access standard and the network standard protocol. Get more images by supporting higher resolution, higher magnification and higher frame rate; by integrating intelligent functions, passive monitoring is active monitoring; through integration with license plate recognition, flash synchronization and other technologies Improve the nighttime effect of road security surveillance and effective video utilization.

The development of the explosion-proof ball machine has evolved from a single explosion-proof shield, explosion-proof pan/tilt, and explosion-proof decoding control box to an explosion-proof integrated camera, that is, the camera, the pan/tilt and the decoder are integrated into an explosion-proof system, so that the user is installed and It is more convenient and simple to use, and it also reduces the safety hazard of man-made installation of explosion-proof pipe fittings. The integrated design provides convenience for construction and application, and improves reliability and stability through a compact structure, reducing maintenance.

The explosion-proof ball machine is a special product in the installation position. Therefore, there are some engineering conditions and constraints different from the general camera in the installation and construction details. Therefore, there are some special precautions when installing the explosion-proof ball machine. of:

1. The cable connection of the explosion-proof ball machine must be carried out cautiously: because the explosion-proof ball machine is usually installed at a certain distance or above, the position is high, the maintenance is not easy, and the connection between the lead wire and the main cable is wired or the connector is connected. . On the line docking, we often see engineers twisting the bare copper wires at both ends and then wrapping them with electrical tape. Some engineers will use the sealing terminals to wind the two wires into the terminals to prevent them from falling off. Another method is to weld the two-wire end in a welded manner and then cover the heat-shrinkable insulating sleeve. Although this is a time-consuming, labor-intensive and cost-increasing method, there is no worries for subsequent maintenance.

2. When the explosion-proof ball machine is installed indoors, the cable outlet must have a certain outlet guide, especially the flat ceiling fixing method. Never push the base directly against the cable. Otherwise, it may be due to thermal effects after a period of time. Or the wire conductor skin effect causes wire breakage or short circuit caused by thermal softening of the wire. The installation in the ceiling should pay attention to the interval between the placement of the 24V power supply transformer and the lighting high voltage power supply. Usually, the sloppy installation method will lead to uncontrollable image power supply harmonics. Wave interference.

3. The special installation of the outdoor explosion-proof ball machine is the water guiding problem of the fixed bracket. Many engineers install the explosion-proof ball machine, often install the fixed frame at a position higher than the cable junction box. When the tail line enters the junction box, it does not enter the line from the vertical direction of the junction box or is waterproofed, so that the rainwater often enters the junction box through the hose through the tail pipe, which causes the line to be short-circuited, which causes Transmission and explosion-proof ball machine burned and damaged.
