B.3 Mounting Mechanics
Two groups of mounting holes are provide on the bottom panel.
One with M2 screws, the other with M3 screws. A tripod adapter
may be used with the M2 screws to mount the PC-1280 on a tripod.
Figure B.3 shows the dimensions (in mm) for the mounting holes.

B.4 Lenses
Standard C-Mount lenses are required for the PC-1280 Camera.
CS-mount lenses may be used with an adapter. According to the C-
mount standard, the focal plane distance from the lens ring outer
surface to the sensor chip optical plane should be 17.52 mm. Some
consumer C-mount lenses may not follow this distance require-
ment, causing imperfect focusing if the lens is tightened. A C-
mount lens extender or a small ring of thickness about 0.5 mm
(0.02”)should solve this problem.
B.5 Power Consumption
The Phoenix PC-1280 Cameras are designed to take power from an
external DC power supply, which provides a DC within the voltage
range b5V and +12V. DC Power out of this range should
not be used. AC power supply can not be used with the PC-1280.
