Relation Table of 24VAC Cable Diameter and Transmission distance
When the cable diameters equal, and voltage wastage rate of 24VAC is under 10%, the maximum transmission distance
is recommended. (As to AC equipments, the maximum allowed voltage wastage rate is 10%) For example: An equipment
with rating power of 80VA and installed at 10 meters away from transformer demands the maximum cable diameter of
0.8mm (square meter).

1. PRECAUTIONS
(1) Do not attempt to disassemble the camera.
To prevent electric shock, do not remove screws or covers.
There are no user-serviceable parts inside.
Ask qualified service personnel for servicing.
(2) Handle the camera with care.
Do not abuse the camera. Avoid striking, shaking, etc. The camera could be damaged by improper handling or storage.
(3) Do not use strong or abrasive detergents when cleaning the camera body.
Use a dry cloth to clean the camera when it is dirty.
When the dirt is hard to remove, use a mild detergent and wipe gently. Care should be taken not to scratch the dome
