In the process of outdoor weak electricity construction, waterproof treatment is a basic work that seems to be disappeared but actually cannot be ignored. Do a good job of waterproof measures, which can not only effectively avoid the faults of lines and equipment, but also greatly extend the service life of the equipment and improve stability.
The monitoring of the construction line connector is mainly based on network cable crystal head, power cord connector, or signal control line connector. Here, I will introduce you to some basic knowledge of waterproof treatment of indoor and outdoor head heads. Welcome to pay attention to understanding.
Good waterproof treatment can allow the equipment to run stably
The waterproof performance of Haikang outdoor surveillance camera and other equipment is designed. For example, it is generally marked that the waterproof and dustproof level of IP65, IP66, and even IP67 is labeled. However, this is only to indicate that the main body of the equipment meets the waterproof level standards. The line joints are not waterproof. We need to take waterproof measures during the installation process.
When the processed outdoor monitoring camera fails, the most problem encounters is that the signal connector does not do waterproof treatment, water inlet corrosion, or even damaged equipment. The outdoor network monitoring camera generally provides the mesh waterproof sleeve as shown in the figure below.
Net port waterproof set component and use effect display
The net port waterproof sleeve (hat) is to prevent the water inlet design of the device. Reasonable use can effectively prevent the water from the mesh port.
The network cable suppresses the crystal head in front of the waterproof set component into the network cable, and then the crystal head is suppressed;
Sequence and explanation of network port waterproof sleeves
Waterproof rubber ring into waterproof shell
Put the trap into the mesh of the camera tail line, and then insert the network cable of the crystal head into the camera of the camera rear network; the gap at the end line network is aligned with the buckle of the waterproof sleeve main body, and put the main body of the waterproof jacket into the network port. Tighten it clockwise.

Waterproof sleeve puts in the tail line and rotate the stuck tightly
Rotate the tail hat of the waterproof cover, and press the waterproof rubber ring without loosening, that is, the installation process of the waterproof sleeve of the mesh port.
If you want to further strengthen the waterproof performance of the network cable connector, you can wrap one to two layers of PVC electrical tapes outside the connector.
Power and other signal cable joint waterproof waterproof
Due to the different forms of power and other signal cable connectors, it is impossible to configure standardized waterproof set components in batches; therefore, power cord joints and other signal wire joints are generally used by wound self -viscosity tape and PVC electrical tape for waterproof treatment.
PVC electrical tape
Self -stick tape
PVC electrical tapes and self -viscosity tape have waterproof performance. The waterproof effect commonly used by the original electricians is poor. Self -viscous insulation rubber tapes Due to disassembly force, PVC electrical tapes are commonly used for waterproof treatment.
Put the connector conductor, tighten the fixed screw, etc.;
Fixed line connector
If the self -stick tape is stretched to about 2 times the original length (PVC tape, it cannot be excessively stretched), and then the waterproof insulation rubber belt is semi -wrapped on the connection that needs to be waterproof. It should be noted that the tape covers the interface. The upper and lower parts are at least 3 cm each;
Stretch the waterproof tape appropriately
Wrap around the connector in a half -match way
After wounding a layer of waterproof insulation tape, then wrapped at least two layers to cover the previously (the wrapped place exceeds the start and end of the previous tape), so that the waterproof treatment measures of the line connector are done well.
