When you first receive the PTZ camera, please make sure it works properly
before mount the camera outside. Note PTZ dome cameras have higher
power requirements than bullet cameras and corresponding IP cameras.
Therefore, how the unit is powered can be critical to its functionality.
Please make sure the unit itself is working, and try eliminating all cabling
factors to set up the bench test.
In short, in a bench test, do NOT extend the power line. Please connect the
camera with its default adapter.
The reason you should NOT extend the power cable during the bench
test is because DC power drops along the cable. Underpower can cause
problems such as 1) screen flickering, 2) unstable infrared (on/off
automatically) and 3) camera spinning recklessly. A bench test helps you
rule out all problems caused by power supply.
For example, if you have previously wired a fixed lens bullet camera and
you remove the old camera and adopt old wires directly on Sunba PTZ
dome camera, this is likely NOT working given two units have different
power requirements.
