I'm having an issue with my "Smarthome Wireless Outdoor IP Security Camera with Night Vision" camera detecting the switch to night vision mode as motion. It makes sense that a change of the entire image would kick off a motion alert, but obviously this should not happen. Is there something I'm doing wrong or do I just have to wait for a firmware update? I'm happy with the motion detection sensitivity but I don't think any change to that would help since the night vision switch does make a lot of difference in the imagine.

I'm having the same problem. Mine seems to switch randomly between night and day mode constantly which sets off the alarm. If I switch it to 320x200 mode, it doesn't happen. (It shouldn't set off the motion alarm if the brightness level changes). Debating whether to send it back or not. I like it other than this issue.

My day/night mode works well, but I think my issue is definitely a firmware thing. When it switches mode it should definitely not trigger a motion alarm. It does it like clockwork at dawn and dusk.

Interesting. Mine is installed under a porch, so the light level must be low and it can't decide which mode to use. Does yours only send one alert, or does it send a number of them?

Not sure why it works in 320 mode though.

I get one alert when it switches modes, that's it. I do know what you're talking about though, while testing inside it would switch back and forth a lot. Now that it's outside (but covered) it only seems to switch twice. Once at sunset and once at sunup. Perhaps they should add a sensitivity setting for that as well.

yeah the 320 mode only thing is weird. Call their support line. Some of the guys on there are great (some not so much).

I'm still having issues with this, does support read these boards?

Negative, you should have seen a note when you registered your ID that this is a user-to-user forum. Smarthome does offer free tech support on a bunch of the gear they sell, but to get that you have to call the phone number that comes on the included Quick Start Guide.

BTW, which other brand cameras are you using that operate differently? I had assumed that it was just characteristic of the technology involved, since computing the difference between a black and white image and a color image and trying to interpret what was a difference in B&W vs. color sensor capability vs. what was an actual difference in three dimmensional objects within those two images would require more computing horsepower than what I understood a $100 camera has onboard. I suspect it just adds up the values of all the pixels in the image, then triggers an email if that number deviates by more than a set percentage. If you programmed it to ignore deviations greater than x%, then you might not get an image sent if movement coincides with light level changes, meaning you might not get a shot of the event if someone walked up to the camera and broke the adjacent light.

If it comes down to something beyond the capability of the processor, which is better: a false negative (not emailing when there was motion) or a false positive (emailing one pic when ambient light causes the camera to switch between day and night modes)?

It's not the act of the image changing as the day changes, it's the image changing when the camera switches between day/night IR modes. A simple signal to the firmware when this change occurs is all that is necessary. Then it could easily ignore the motion detection code during that switch. No real processing power necessary. Pin goes high, ignore motion detection. Done.

Personally, I wouldn't want to miss motion just because it coincided with a shift between day and night modes. That'd leave me vulnerable if someone intentionally manipulated artificial light levels. Do you have other cameras that work that way?

I think you could live with the less than second in motion detection. I'm quite certain a 500ms "blackout" could be tolerated in any environment that a $100 budget camera would be used in. Regardless, a simple check box could allow you to turn it on or off in the configuration if you really wanted to be bothered twice a day with worthless images anyway.

This is the first camera I've used with an auto detecting IR night mode, but regardless of what other cameras do I'm sure there are others that are tired of getting emailed twice a day just because the camera is switching modes.
