Handle more than one camera at the same time in the plugin

Suggestion: Be able to handle more than one camera at the same time in the plugin.

I use 4 cameras, but in my opinion it should be a priority to add options that work for everyone, because I needed to mod the plugin.py and it's perhaps difficults for over:

• python or python3 choice (my setup: self.process = subprocess.Popen(["python3")
• path choice (my setup path="/opt/domoticz/userdata/plugins/reolink/camera.py") unless you put everything in one file .py
• choice of detections person, motion, doorbell, ... (my setup: CAMERADEVICES = {"Person": 1} DEVICENAME = {"People": "Person"} RULES_DEVICE_MAP = {"PeopleDetect": "Person"} THREADDEVICES = ["Person"])

I am curious about your setup when it comes to the plugin folder. I changed to HomeFolder in 0.0.2 which is "Folder or directory where the plugin was run from.", does that not work for you?

Python or Python3 - camera.py requires python3 so I guess I can change to python3 as the default name for the python binary. I assume you have both python2 and python3 installed in your system.

The detection rules are interesting. I am using data from the camera to identify what sensors should be created. That would mean a camera that supports the detection of pets should have a sensor that is triggered for that. In your example you would disable some of those sensors. Why not just hide the sensor in the Devices tab?

Yes camera.py path folder work now, thank for mod. I use the official domoticz docker, and only python3 is installed in default, so I need to mod in plugin.py "python" to "python3"

I use 4 reolink cameras, and have too many devices created. For my alarm senario, I only use person detection, other is useless for me

Ok, I have changed to "python3" now.

I will think about how to solve the creation of devices. Easiest I guess is to allow for some sort of list of what devices is created.
