Update runHomeSecurity.py

png is to big! I got an error of sending 11 MB isnt supported.

Choosing jpg vs png should be an input argument. Maybe add that to the config file and check it before sending the image. Otherwise looks good, I didn't think about the maximum size because I use it on the "sub" stream which runs on 640x480.

I found the problem.
My streams are running on "main" channel because my version of reolinkapi didnt had the following implementation:
https://github.com/ReolinkCameraAPI/reolinkapipy/blob/5f3b6f9a5b4ee1fba7e362faea6174cd214b4506/reolinkapi/camera.py#L40

I dont know why it happend, i deleted the directory (/home/user/.local/lib/python3.8/site-packages/reolinkapi) and made a new clone.

Shall i made a new commit with a frame size/dimension check for the first frame of each cam?
