Amcrest 2MP Outdoor PTZ POE+ Alarm/Audio specs?

As usual the chinese manual that comes with this thing lists nothing about the specs of the alarm or 2 way audio.

Where can I find this information?

Are the alarm wires just a low voltage relay? And what is the audio impendence/level? Do the mic and speaker need to be powered? Why don't they tell you this? Why cant they list compatible hardware?!? Its as if they don't give a crap if the customer gets it working correctly or not. I can imagine someone hooking it up wrong and blowing the circuit immediately.

Any guidance greatly appreciated!

I am sure it is like the Dahua so they are just simple relays. You will need a separate power supply for the mic and audio.

I would agree that for that kind of money Amcrest (or any vendor, for that matter) should provide better documentation.

Any info for this OP, @CarlosBarletta ?

Right, but what voltage, impedance, etc., for the audio equipment? Im assuming mic level input, but what about the output?

Would these work for the input audio?

Thanks

Not sure about your specific camera model, but tested this weatherproof amplified mic/speaker on low level audio input/out signals, with good results. The current consumption is low, you may use the 12V camera power (or power extraction if needed)
