API call to Dahua camera when connected to POE of NVR

[Firepeet]

Hi guys,

Before i make a choice if i will buy a NVR with or without POE, i have the following question:
I know that it's possible to switch the warning lights of a TIOC camera on and off with an API call with the following code when the camera is connected to a LAN:

ON:

http://ip-address/cgi-bin/coaxialControlIO.cgi?action=control&channel=1&info[0].Type=1&info[0].IO=1

OFF:

http://ip-address/cgi-bin/coaxialControlIO.cgi?action=control&channel=1&info[0].Type=1&info[0].IO=0

Is this still possible from a local network if the camera is connected to a POE port of a Dahua NVR?
Because i want to control the alarm lights and sound by API with my Fibaro HC3, connectend on my LAN.

Quick answer is no because the NVR puts the cameras on a separate IP subnet (usually 10.x.x.x), but there are ways to bridge it but then you could be giving your cameras internet access unless you are VLAN and what not.

Thanks for your quick but clear answer.
Is it possible to control the sound and light of the cameras by sending api strings to the NVR?
Otherwise i have 3 options that i can do:

using a NVR without POE
Bridge the VLAN of the NVR to LAN
Using the alarm input wired to a Zwave switch

any other options?
