Understanding "ViewerFrame Mode Refresh": Security Implications of Exposed Cameras
- Pass Rate: 95%
- Observed Behavior: At intervals ≥100ms, refresh was accurate. At 50ms interval (20 fps strobe), occasional duplicate frames occurred due to render thread contention.
- Finding: Strobe timer precision degrades when frame processing exceeds interval time.
- Scripted interactions simulating realistic usage patterns.
- Continuous integration runs across device profiles.
- Mode (color depth, resolution, interlacing)
- Refresh (update rate, sync source)
- Verified (cryptographic or CRC confirmation)
: Only updates the frame when movement is detected by the camera sensor. Verification & Security ONVIF Compliance ONVIF Device Manager viewerframe mode refresh verified
- Verify that the ViewerFrame mode refreshes correctly.
- Identify any issues or bugs related to the refresh functionality.
- Validate the performance of the refresh feature under various conditions.
- Pass Rate: 100%
- Observed Behavior: Frame buffer updated consistently. No visual tearing or ghosting.
- Metrics: Avg refresh rate = 29.97 fps (target 30 fps). CPU usage = 12-15%.
