Had my camera for a couple of weeks and recently had it switched off for a few days. After switching back on it doesn't appear online in my app neither does it talk on boot. I've tried holding the reset button but doesn't reset either.
The two red LED's are on and the speaker seems to click every few seconds.
This also has happened to me except the two LEDS don't come on and no clicks. Have you tried another power supply?
Just sent off a support ticket.
