You cannot connect multiple extension cables to each other.
• This guide covers connecting cameras to your security recorder only. For full instructions on
installing your cameras, please refer to your camera’s documentation at lorex.com.
NOTE: To receive automatic firmware updates and enable remote viewing with mobile apps, a high
speed Internet connection is required (minimum upload speed of 5Mbps required for 4K viewing;

IMPORTANT: The system will automatically match the resolution of the connected monitor the first
time you use the recorder. If you need to switch monitors, make sure you set the recorder to an
output resolution supported by the new monitor before switching. See Changing the Recorder’s
Output Resolution on the rear for details.
