In order to do this, you’ll need to do one of the following options:
A.) Ensure that the extender’s network name and password are identical to the router’s. This can cause an issue with the camera trying to bounce between the two signals, and really only works well if the router’s signal is almost non-existent in that area.
B.) Purchase a secondary sync module. Assign the sync module to the extender’s network, and assign that camera to the module. (Extra modules go on resale websites for around $20).
