Frequently Asked Questions

What makes a BNC connector waterproof?

A waterproof BNC connector is designed with additional sealing mechanisms, typically including O-rings, gaskets, or specialized materials that prevent moisture and dust ingress. Our connectors feature a silicone O-ring and a unique compression fit that creates an IP67-rated seal. This ensures reliable operation in outdoor environments, such as those exposed to heavy rain, high humidity, or even temporary submersion. Unlike standard BNC connectors, the waterproof design maintains signal integrity under these harsh conditions, making it ideal for CCTV systems in coastal areas, industrial facilities, and critical infrastructure.
Proper installation is crucial for maintaining the waterproof performance. Our connectors are designed for crimp termination, which provides a secure and reliable connection. First, strip the coaxial cable to the recommended length (typically 8mm for the center pin and 5mm for the braid). Insert the cable into the connector body, ensuring the center pin is aligned, and then use a crimping tool to compress the ferrule. Finally, tighten the compression nut to the specified torque. Our product datasheet provides detailed steps, and we offer installation guides on our website. If you have any doubts, our technical support team is available for assistance.
Yes, our Waterproof BNC Connector is compatible with CCTV systems that use analog signals, including those with power over coax (PoC) technology. The connector's design maintains a proper impedance (75Ω) and has low insertion loss (≤0.2dB), ensuring both video and power signals are transmitted with minimal degradation. However, for PoC systems, it's essential to verify the current rating of the connector. Our standard connector supports up to 0.5A, which is sufficient for most cameras. For higher power requirements, please contact us for a customized solution.
The lifespan of our Waterproof BNC Connector is influenced by the operating environment, but under typical outdoor conditions, it is designed to last over 10 years. The nickel-plated brass body and Teflon dielectric resist corrosion and degradation. In our salt spray tests, connectors showed no significant corrosion after 500 hours, corresponding to years of coastal exposure. Additionally, the pull-out force of 50N ensures a secure grip that prevents loosening due to vibration or thermal cycling, further extending the product's life.
