We've had our 340M up and running for a couple of months now. For the first month it was 100% reliable. Then the camera 'crashed' and had to be power cycled to come back online... It worked fine for around a week... Then it 'crashed' and had to be power cycled to come back online... It worked fine for a couple of days... and so-on ... now it seems to crash roughly once a day. There isn't an obvious pattern. Sometimes it happens in the middle of the day when the heater is turned off, sometimes it happens at night. There isn't an error message, just the software stops. Power cycling the camera brings it back on line every time but it's extremely frustrating. All and any advice of where to start appreciated please.
