My current DB is the RCA version (Latest Firmware 190124 - according to Ezviz App ) and my tests were taken directly on the surface of the unit (front and back) not mounted & with out the cover. It had been running for at least 30 minutes. Temps taken with a cheap infrared thermometer, back of wrist read 89 degrees, it was 70 degrees Fahrenheit indoors, test taken 6" away, no dedicated stream running yet, and using a 24VAC 40VA transformer. Depending on the accuracy of my thermometer, that is like 50-60 degrees hotter than the ambient temp. I am returning it to amazon and I have a Nelly version on the way so I will test and post the results of that here. I have not found any post of a hack to get into the web interface, does anyone think or know if that might be possible or has it been ruled out as not existing?
Some one did mention that IPC boards typically run warm or hot.
Here have two camera boards that I am testing (38mm). These are both using Hikvision OS. Slower than the doorbell cam when using the batch configuration program. These have been running now for a couple of weeks in the basement. Both are warm to the touch. Checking temps...batch configuration program shows a temperature tag but no temperature is seen.
Ambiant temps in the unfinished basement is 66 °F and IPC boards temps are 89-90 °F
