2025-07-16Last updated
Before you can enroll BEST Wi-Q locks in Security Center, you must configure the Over-Watch plugin for
Mercury LP4502 controllers.
What you should know
All Mercury LP4502 controllers under the same Synergis™ Cloud Link unit
must be configured with the same Over-Watch username, password, and listening port.
If you want to move a Mercury LP4502 controller that is used in a BEST Wi-Q integration
from one Synergis Cloud Link unit to another, the Over-Watch plugin must be
enabled on the target Synergis Cloud Link unit before moving the
controller.
