What should be paid attention to in factory installation monitoring?

Need to pay attention to the following items:

1, grounded

The grounding of ball machine is mainly divided into shell grounding and internal electrical grounding. Enclosure grounding is mainly used to prevent electrostatic accumulation, leakage, etc. Outdoor ball machines need to be equipped with external lightning protection measures. Generally speaking, the outdoor spherical camera shell installed on the pole bracket has been naturally grounded and protected without special treatment through the screw connection with the metal bracket.

2. Grounding circuit

Even if the equipment is effectively grounded, the zero potential difference between the ball machine and the central equipment and the imbalance of the power load will still lead to the grounding potential difference. This potential difference will produce a closed loop formed by current passing through coaxial cable, which will cause interference, thus affecting the normal transmission of video signals, usually manifested as horizontal clutter in the middle of the image.

3. Waterproof material

Outdoor hemispherical camera installation must be waterproof. For suspension installation, there is a gap between the dome and the bracket. If it rains or snows, water will seep into the room along the gap, causing harm. Therefore, waterproof and sealing measures should be taken during installation to prevent rainwater from entering from the threaded joint.

Matters needing attention in safety monitoring system:

1, night vision

Generally, the outdoor environment of factories and warehouses needs night vision system, even if there is no light, it should have good monitoring effect. Therefore, infrared night vision system has a broad application space in factory monitoring.

2. Network transmission

Most enterprise managers need monitoring systems with network functions, which can be monitored on LAN and Internet. The current monitoring system can basically meet the needs of the owners.

3. System connection of interlocking mechanism

Now many factories have branches or chain stores in different places, and they can have networked monitoring systems to realize unified management.

4. Long-distance transmission

Many large factories cover a very large area, and the farthest distance of cameras is close to 2000 meters. It is necessary to realize optical fiber transmission, microwave transmission, twisted-pair video transceiver, video recovery host and single-wire communication.
