Why can I pan and tilt my cameras from my remote, but not from my computer?


If you are having problems with your remote control or motion sensor, it is always a good idea to first make sure you have fresh batteries in it.

Your USB Transceiver (CM19A) uses radio frequency ("RF") signals to communicate with the pan/tilt mechanisms, so it is best to set up the interface for optimal transmission. Here are some options to try:

  • Position the CM19A as high as possible on the wall, and as far away from your computer as possible.

  • Hold your remote control right next to the CM19A and see if it can still move the cameras.

  • Use a USB extension cable to re-position the CM19A further away from the computer.
