Cameras detect light changes as motion

[Techie007]

Hey linflas,

Sorry to hear about the issues, do you have trees in the picture or shadows of trees? Is this real motion, or is it from video noise? If this is the problem, to be honest it's a hard thing to fix. Outdoor cameras, generally regardless of brand, tend to have false alarm issues when they are pointed in areas that produce shadows on cloudy days, or movement of trees or leaves in the wind.

The cameras can also sometimes have sharpening noise in low light, which can cause a lot of motion alerts in the mornings or evenings. You can try reducing the sharpening possibly. I'd recommend playing with the settings to see what combination of them minimizes the alerts (although I know you've been fiddling with this for a while).

The DVR does have motion sensitivity settings that may be too high. It's a balance of the sensitivity settings and masking out unwanted areas of constant movement, such as trees, bushes, shadows, leaves, etc. If this still doesn't help, I might recommend the following:

PIR/Motion Triggers - Use these to trigger your recordings instead of using the camera motion.

Third party software - Software like Blue Iris is quite advanced in terms of motion detection algorithms and does a very good job at zone detection, which is specific to what you are trying to do. I'll send you some more information in a PM about this software if you'd like to try it out to see how it works.

We definitely are partnered with Dahua on these DVR's, and we do rely on them for updates to issues like this. That is why this feedback is critical to us. In order to make the product better, we have to listen to our customers, and in turn we do our best to push Dahua's R&D teams to assist us in fixing issues just like this over time. I've been consolidating a lot of feedback on our DVR and NVR products and adding to our issue list, which Dahua can go over in more detail. If you can send me some more information via support@amcrest.com such as screenshots of your settings and motion detection video clips that were triggered, this can definitely help create a detailed case for more development into motion detection algorithms.

Thank you for your interest on this topic. These cameras and DVRs seriously have the worst motion detection algorithm I've seen in any similar product. It's almost completely useless for anything but the most controlled of environments. If you guys could eliminate the current "motion detector" completely and simply write code to analyze the motion vectors already well calculated by the H.264 encoder, you could have a vastly superior product at a lower CPU and memory cost.

I just want to know is amcrest on track working on this issue? or not at all? or technically not possible to write some filtering algorithm?

Can somebody please tell me how I would go about adding an external PIR to an Amcrest bullet camera? Don't even know where to begin.

It's difficult to filter this out. False alarms for some people may be real alarms for others. I do a secondary filtering at the server where the video and snaps go. By comparing the snapshot trigger images in a shell script using the convert command from ImageMagick you can filter them out yourself.

The exact same issue happens to me when a CCTV installation company come to my home to set up HD security cameras in our dining room.After 4 days of the setup, the camera gives an error. Then I contact the technical support team for a fix, they suggest me to update the firmware camera. After updating firmware now there is no issue with my camera.

It is 2019 and I have the same problem. My IP3M_H2XW constantly records to the cloud, though there is no real motion. I have set the sensitivity to 50 and still every 30s or 1min there is a video of nothing that is perceivable to the human eye. Looks like every pixel change is triggered as an event. This is just useless as the main reason for getting a security camera is to record a real event.

With 100's of videos, how am I going to figure out when was a real even recorded?

I have sent many emails to tec support and posts about this in this forum and so far no resolution. Asked for a RMA but have not received the RMA #. It has been 29 days since I bought this and I am afraid I will be stuck with this once it is 30 days.

I played with sensitivity and threshold values and cant make the camera stop recording NULL events every few seconds. I dont have this problem with the Amazon Cloud Cam. It only has sensitivity setting. I set it at high and it only records real motion. Amazon has human detection for paid membership. I have to try that and see how good that is. The downside of the Amazon Cloud Cam is that there are no image adjustments like brightness, contrast, black level etc. and the video is highly compressed and so lacks details.

Both Amazon Cloud Cam and Amcrest IP cameras do a poor job with low lighting unless I can use external IR illumination with either of the cameras. The built in IR LEDs dont help if placing on a window due to reflection from the glass.

I have already posed the question if Amcrest IP cameras can detect external IR illumination if I turn off IR night vision to turn off the IR leds. Got no answer.
