Dahua 59225 PTZ power problem

I have a new 59225U-HNI, Mikrotik POE switch CRS112-8P-4S-IN (it supports both 802.3af and 802.3at). I also have the 48V power adapter needed for af/at POE.

The camera is 45m away (~148ft) with the same amount of cable - Lanmark (by Nexans) Cat6 AWG24 F1/UTP, with cat6 shielded connectors.

Using my Noyafa NF-8061 I can measure the POE voltage over the cable - 48.1V.

When i plug the camera in i can only feel the fan inside working, it isn't doing the self analisys "dance", on the Mikrotik i can see that there is not enough mA supplied to the camera.

When using a premade 5m (16ft) patch cable cat 6 AWG 23 the camera works fine.

Any thoughts or reccomendations as to how to remedy this problem?
Should i get a more powerful (more Amps) 48V power adapter for the Mikrotik?
Get a 23 AWG cable (Draka most likely)?
Make the Mikrotik somehow send more mA to the PTZ?

Positive that the cable is pure solid copper, and not copper clad aluminum?
Confident the rj45 crimps are good? Maybe, redo them.
Awg23 would be the next step. If you can, try a different POE+swtich.

Pure copper, rj45 crimps are ok.

Next step will be to use a higher Amp power supply for the switch, and try a AWG23 cable.

Problem solved:

Old Mikrotik CRS112 switch PSU: 48V 1.46A
New Mikrotik CRS112 switch PSU: 52V 2.5A

SD59225U-HNI is up and running.

@looney2ns Thank you for participating!

I hope this thread helps someone in the future.
