- PURPOSE
- Record the same target before and after the lighting change. Include a person approaching, a vehicle or reflective surface where relevant, and a subject moving at the expected speed.
- CONDITIONS
- State whether the scene supports detection, observation, recognition, or identification for the named target. Include clip time, camera settings, firmware, light condition, and any unresolved limit.
- LIMITS
- This is a planning or editorial guide. It does not replace a site survey, current official source, legal review, or vendor acceptance test.
Test the difficult period
Record the same target before and after the lighting change. Include a person approaching, a vehicle or reflective surface where relevant, and a subject moving at the expected speed.
Write an evidence-based result
State whether the scene supports detection, observation, recognition, or identification for the named target. Include clip time, camera settings, firmware, light condition, and any unresolved limit.
FIELD CHECKLIST
Record the result, not only the intention
- Test at the actual night condition and target distance.
- Include movement, headlights, reflections, IR, and backlight.
- Compare live view with recorded playback and export.
- Record the image task achieved and the task not achieved.
- Keep the test clip and settings with the acceptance record.
FAQ / LONG-TAIL QUESTIONS
Frequently asked questions
What is a night CCTV test?
It is an on-site test of low-light detail, exposure, motion, headlights, reflections, IR, and recorded playback at the real camera position and target distance.
How do you test night vision CCTV?
Test the real target during the difficult period, include movement and reflective surfaces, compare live view with recording and export, and record the achieved image task, settings, firmware, and unresolved limits.
Why can a camera look good live but fail at night recording?
Exposure, IR reflection, motion blur, bitrate, codec, recording settings, and playback or export processing can change the usable result. Validate the complete recorded workflow, not only the preview.
