i installed 6 of these cams, those light bulb cam as posted by op, e3diot, bought from 6 different places, in two different homes in 2 cities. Worked very nice as an internet cam. I also bought the cloud service, standard plan, hope to have these function as security cam. The motion detector work almost instant, if it is already online when motion happen. Otherwise, there is a 20-30 s delay for the motion detector to get active. Here is the problem, there is another 10-15 seconds additional delay after the motion detector triggered. In other words, if the mailman, or the UPS came to door front, drop your package and leave, and the total time in the ‘field’ is less than 10 seconds. You would not get anything, not even an alert. Somebody needs to be in the field over 20 seconds or more for you to have an alert and capture something. This is just my experience, maybe someone with more tech knowledge can shed some light.
In order to cut down the ‘latency’, I disabled motion tracking, microphone. will report back after a week or two, see whether these maneuver helps. I installed the cams and bought the cloud service for security. However, the latency defeat these purpose. So, if a guy stands in front of door, ring the bell, and wait for awhile, it will capture. However, if the walmart or UPS, just come and drop the package, you will only see the package, not the exact delivery. Same token, if the porch pirate come to steal in less than 10 seconds, even the alert wont get triggered, less mention capturing the video
