ESP32 Camera 600m range using ESP NOW!

My aim was to make a target camera for shooting, sending numeric (so clear) picture and cheap in case a bullet hit the cam.

Range was better than expected, 600m and it’s not out of range with simple stick antennas, it’s probably possible to achieve much more with good directionnal antennas...

[Update 11/02/22] The little pannel antenna seem to offer 15% more signal force in WiFi at the distance where the stick antenna is at limit.
