Cleaning MIC440
The MIC440 features an automatic cleaning cycle to ensure proper operation during daily use.
The cleaning cycle occurs every 24 hours, based on a user-defined setting in Camset.
During the cleaning cycle, the camera initiates a full-speed pan rotation in one direction, stops
the rotation, then starts a full-speed pan rotation in the other direction. During the cleaning
cycle, only some functions are available and the camera closes the Iris so that no picture is
visible. The cleaning cycle interrupts any previous activity (for example, tours, autopan,
sequence, scan), but will not interrupt an alarm condition. Once the cleaning cycle is
complete, the camera returns to its previous activity, and the pan, tilt, iris, and focus settings
are returned to the position they were in before the cleaning cycle began.
Cleaning Cycle Operation
The entire cleaning cycle takes approximately three (3) minutes and is divided into three
phases:
– Pre-cleaning Phase: This phase starts 60 seconds before the first cleaning phase. During
the Pre-cleaning Phase, an operator can delay the cleaning cycle for five (5) minutes or
can cancel this instance of the cleaning cycle.
