It shouldn’t even be able to run it, because the x permission bit is missing. As far as I know binaries can’t include icons on linux, so it would look different too.

Voltage drop probably isn’t a problem here, because your sensor draws verry little power. If you can get POE for cheap then thats a better option.

You could get a cheap usb a to c 2.0 cable, cut it and extend the wires with some 4 conductor J-YStY cable or what ever is common where you live. The sensor probably doesnt use enough power to cause a significant voltage drop.

You have to check the cameras manual, if it says passive poe and a voltage, then one of these injectors with the correct voltage will work, if it doesn’t then you need a active poe injector with at least the required power (af < at < bt).

Im doing this with esphome, i replaced the thermostats with dht22 sensors and wired the valves via solid state relays (one for each zone) to the esp. Im using an esp with ethernet (wt32-eth01 clone), but wifi can work, if you can place it outside of the metal box of the heating system.

For control you can use a pid controller. I think there are some, which can run directly on the esp if everything is connected to the same esp.

Note: Dont use dht22 in the bathroom, it will slowly get less accurate when exposed to high humidity. Running the onewire of the sensors straight through existing 5 conductor thermostat wire/1.5mm^2 wire works reliably
