Motion Detection Recording Constantly at Night
As the title states, I'm having an issue with SecuritySpy's motion detection continually recording at night. I'm using a newly purchased Hikvision DS-2CD2432-IW, recording 1080p@30FPS. I have motion to start recording after 2 seconds, and then at minimum record 10 seconds after the motion, saving in one video per day.
To my amazement I woke up this morning and my video file was over 30gb, and it's 95% just recording the darkness (IR illumination) at night with no detectable movement. I checked before I went to bed and the motion sensitivity bar is set at 70% and in total darkness the meter which shows detected movement is full 100% of the time. Why would SecuritySpy be detecting so much "movement" with just night time IR? This seems to only happen on a camera of this quality, I attempted the same on a crappy Foscam and the IR at night doesn't cause SS to detect "motion" and continually record.
Any suggestions would be great.

My apologies for the rant. I may be an idiot.
The camera is set to default with the date and time shown on the video stream. In the dark with the IR on it seems that the constant updating of the seconds may have been triggering the motion.
I've removed the date and time overlay and set it in SecuritySpy. I will test it tonight and report back. -
Sorry you've experienced this problem - it is plausible that the date/time display might be triggering SecuritySpy's motion-detection algorithms. Either that or the amount of noise in the video image at night may be doing so - but the amount of noise in low-light conditions varies wildly from camera to camera and may not be a problem at all with yours.
Use the motion mask and draw in green over the camera's date/time display. We'll see what happens tonight! -
I have the same problem during nigh and it is product from noise, I think it will be a good idea to program security spy to a schedule setting for sensitivity trigger.
Will be sensitivity 70% daytime (between sunrise and sunset) and 30% during night.
Is it possible in next release
Thanks -
Hi Cesare,
70% is a very high sensitivity - it's not normally required to have a sensitivity much more than 50%. If you use 50%, does this work OK for both day and night?
Allowing for different settings for the day compared to the night would be a useful feature, and it is one that we are considering for a future update. -
I have this camera, and I like it a lot. From within the cameras firmware, check to see that the day/night switch is set to auto. I have my sensitivity set to just 48. You also need to check the audio sensitivity, I keep mine disabled. You can also set up a schedule within the camera's firmware, to adjust for noise when using the IR... But I've found this hard to do with an indoor camera as schedules are not consistent like an outdoor camera with sunrise and sunset.

Thanks for the comments everyone. Removing the Date/Time OSD from the camera did nothing to change the fact that SS still constantly recorded at night. I was doing some testing on my own and found that reducing the sensitivity to a range in the 50's prevented recording at night, but also prevented SecuritySpy from recognizing me clearly walking across the room. I had the motion meter up on my TV while I walked in the room in the darkness and the movement never triggered enough movement for SecuritySpy to start recording. As a matter of fact, I was doing jumping jacks in the clear view of the camera and it wasn't detecting my motion enough to trigger it.
As jay stated, being an indoor camera it's nice to have the IR set to turn on automatically because it's not as cut and dry as sun down/up. If I set the camera to turn the IR on with a certain schedule I can manually adjust picture settings that would probably help SS better trigger real motion and ignore noise, but that's a less than ideal situation since the IR may be on during unnecessary times and off when it's needed. I will continue to test and hopefully be able to get a happy medium.
