1. How can I achieve a stronger and more reliable signal to address signal loss or frequent disconnections between my wireless camera and NVR?

We highly recommend adding an "Extension Antenna" to enhance signal strength and connectivity. This is a strongly advised solution if you're experiencing signal loss or frequent disconnections between your wireless camera and NVR.

Installation Guide:

  • For the NVR: Locate the two black stick antennas at the back of your NVR when viewing from the front. Replace the left stick antenna with the Extension Antenna.
  • For Cameras at Disconnected Locations: Replace the existing stick antenna on the camera with the Extension Antenna.
  • Mounting the Extension Antenna: The Extension Antenna comes with a magnetic plate at the bottom, allowing you to easily attach it to metal surfaces. Alternatively, you can secure it using glue or tape.
