We now have temperature monitoring, it is nice, you can interpret the datas.
If you think that a fall of top temperature, follow by an increase of entry temperature means that bees prepare to swarm, it could be interesting to have confirmation with an image.
I decide to get an IP camera, they need network and a bit of power, no USB driver, it should be simpler.
I have found a 30€ IP camera: Wanscam JW0008 and a HW0043
Scanning network to find the camera
Disable green led
192.168.0.19 is the IP address of the camera.
There is a green led blinking all the time, you can switch off the led with an http query :
in this example, I have configure the camera to listen to port 80 so that I need not specify the default 99 port.
The default login is admin, with empty password
Get a snapshot
Open video in VLC
Different IP ... 192.168.0.20
