HELP with Dahua network PTZ camera DH-SD1A404XB-GNR

Looks like the same issue with the 2 posts you made in another thread on Monday. Anyway, here goes:
According to the specs, the camera is powered by either 12VDC on its coaxial power connect OR over the CAT-5e cable by 802.3af-compliant POE. That POE power should come from a 802.3af/at compliant POE switch or POE injector rated sufficiently (in Watts) to power the camera.
It sounds like you tried a passive 24VDC injector from a Ubiquiti or TP-LINK wireless access point which the camera is NOT rated for so hopefully you did not damage your camera. It's always best to consult the manufacturer's specs or manual BEFORE powering up a device.

Tony, thanks for the quick response and link to the specs. Which POE make and model do you suggest using? I contacted dahua but they refused to assist simply because it wasn't an american market model and the weather here is beginning to cool and wanted them working as they should before gets too coldLooks like the same issue with the 2 posts you made in another thread on Monday.

Goalake POE-1050 works okay for me. 4 ports plus one for LAN. These are no-fan cooled, dead silent.
Maybe a whopping ~$18 on AMZ. Unmanaged switch. Note that if these el-cheapo's are loaded to full capacity [all 4 ports POE] the life span is VERY short unless you force-fan-cool them.
At this price, buy two -keep one new on the shelf as a spare and just never plug more than two POE powered devices into each box (which will keep the power supply under-loaded) to extend the life of the switch.
