Anyone Else Notice Dropped Frames / Stutter on Thermal Camera

[jsmith]

I've reviewed several videos, and this problem seems random. I have my unit powered by the 12V Adapter and it is not hardwired. I am not noticing this issue on any other camera (Front / Interior or Rear Feed). It happens RANDOMLY on the Thermal Camera Files and ONLY HAPPENS at the beginning of files. The Footage will "Freeze" Or Stutter a Few Seconds and record normally. Again, I have to go through numerous files and this appears to be random.

Anyone else able to Replicate? - You'll notice the Audio Plays Normally, but the video itself freezes.

Yes I have noticed similar dropouts. The one I just found was 30 seconds into a 3 minute file.

This could simply be the thermal sensor performing an automatic calibration. Thermal cameras periodically recalibrate themselves, and during that process the image can freeze briefly while the audio continues normally. Automotive night vision systems with thermal cameras do the same thing.

Yep. My HIKmicro does the same. Looks like recalibration of the image.

Got a Reply from my Inquiry:

Thank you for the detailed feedback and the sample video.

The stuttering/freezing you’re seeing on the thermal camera footage is a normal phenomenon. When the thermal camera first starts up and the sensor has not yet reached thermal stability, the shutter switching interval is random.

Once the thermal sensor stabilizes:
- In Normal mode, the shutter switches every 3 minutes
- In Rain/Fog mode, the shutter switches every 30 seconds

The brief freeze or stutter only occurs at the moment of shutter switching and is expected behavior.

Please let us know if you notice any other unusual issues after the camera has fully warmed up.

Best regards,
Penny

Yep, I just noticed this behavior as well. Good to know it's a characteristic of thermal imaging rather than this specific implementation. While I was testing yesterday in the living room, I noticed the thermal camera "cycling" with clicks here and there. This was probably the 3 minute cycle that Penny is pointing out.
