Events not triggered if too many are selected

[dcro]

I have a IPC-5442T-ZE camera and I noticed that some events are never triggered in home assistant (listening for dahua_event_received), for example the ParkingDetection event. The camera is running the latest available firmware.

After a bit of testing with my camera's event stream in /cgi-bin/eventManager.cgi what I noticed is that when the list of events specified in codes[] is too long, the camera's firmware will simply trim it and only trigger some of the events (it seems to trim at around 100 chars).

For example this works to trigger ParkingDetection:

/cgi-bin/eventManager.cgi?action=attach&codes=[VideoMotion,CrossLineDetection,VideoBlind,CrossRegionDetection,SmartMotionHuman,ParkingDetection,SmartMotionVehicle]&heartbeat=5

while this doesn't work:

/cgi-bin/eventManager.cgi?action=attach&codes=[VideoMotion,CrossLineDetection,VideoBlind,CrossRegionDetection,SmartMotionHuman,SmartMotionVehicle,ParkingDetection]&heartbeat=5

I think it would be better to always listen for codes=[All] in client.py instead of using a specified list of events or at least give users the option to select All as one of the options when defining the list of events for the plug-in.

You could try what is suggested in this thread by tweaking the client.py file. I have done it and although it has not fixed my issues, it doesn't appear to of broken anything either so may well work in normal circumstances.

@mooton85 Thank you for the suggestion, I applied the same change to client.py and it works great for me as well.
