Can I Protect the Camera without Using Reolink Weatherproof Cap

The answer is YES.

Applies to: All Reolink cameras with an RJ45 Ethernet port

The weatherproof cap is designed for Reolink PoE cameras, which is used to cover the Ethernet cable connector to prevent water intrusion to ensure the RJ45 connector works and has a long-lasting performance. It is easy to install a weatherproof cap. So we kindly advise you to use Reolink weatherproof cap to protect the camera.

Alternatively, you can use other weatherproof materials to protect the wire ports, such as weatherproof tapes, junction boxes, etc.
