Do not manually back drive the pan or tilt axis by hand. Back driving may strip teeth off the internal gears 
and in so doing will void the warranty. 
M8 Stainless steel nuts, bolts and washers should be used to secure the base to the mounting surface. Suitable 
sealant or a gasket should be used between the camera base and the mounting surface. 
 
Ensure that the 12 pin connector is located into the camera base plug and that the lock ring is tightened. Ensure 
that the base compartment containing the 12 way connector is moisture proof. On inverted units it is very 
important that the connector area is water tight to prevent water pooling around the connector. 
 
The MiC400 series of PTZ cameras comes with a security attachment point as standard. This should be attached 
to a safety chain which in turn should be attached to a secure part of the structure.  
 

 
The camera and camera housing are electrically isolated so the housing should be safety earthed regardless. 
This safety earth should be a bonding connection to the camera’s outside case. E.g. one of the securing screws 
used for bolting the camera down. 
 
The camera should be earthed at one point only to prevent earth loops and thus hum bars appearing on the 
camera picture in the control room. 

Note: all connections must be made
