Video Recording Issues — Troubleshooting Guide

Common Recording Problems

Video recording issues fall into several categories:

• No recording at all — nothing is being saved
• Gaps in recording — some periods have footage, others don't
• Recording stops after a period — storage full or overwrite disabled
• Motion recording not triggering — events are missed
• Playback issues — footage exists but won't play properly

Step 1: Check the Hard Drive

The hard drive is the most common cause of recording failures:

Hard Drive Not Detected

• Go to NVR Menu → HDD Management or Storage
• If the HDD shows as "Uninitialized" or "Error", the drive needs attention
• Try initializing (formatting) the drive from the NVR menu
• If the drive won't initialize, it may be faulty — power off the NVR, reseat the SATA cables, and try again
• If still undetected, replace the drive. Use a surveillance-rated drive (WD Purple, Seagate SkyHawk)

Hard Drive Full

• Check the HDD status — if it shows 100% full and overwrite is disabled, recording will stop
• Enable overwrite (also called "circular recording") to automatically delete oldest footage when the drive fills up
• Consider upgrading to a larger drive if you're losing important footage before you can review it

Hard Drive Health

• Surveillance drives are designed for 24/7 operation but still have a limited lifespan (3–5 years)
• Check S.M.A.R.T. status if your NVR supports it
• Replace proactively — don't wait for complete failure. If you see read/write errors or the drive makes clicking noises, replace immediately

Step 2: Verify Recording Schedule

Your NVR may be configured to only record at certain times:

• Go to Recording Schedule or Record Setup
• Check that recording is enabled for all channels (cameras)
• Verify the schedule covers 24 hours / 7 days if you want continuous recording
• Check the recording type:
• Continuous: Records 24/7 (recommended for critical cameras)
• Motion: Only records when motion is detected
• Alarm: Only records when an alarm input is triggered
• If using motion recording, ensure the motion detection is properly configured (see Step 3)

Common Schedule Mistakes

• Recording set to "motion only" but motion detection is disabled
• Schedule configured for weekdays only, missing weekends
• Timezone set incorrectly, causing schedule times to be off
• Holiday schedule overriding normal recording

Step 3: Fix Motion Detection Issues

If using motion-based recording and events are being missed:

Motion Detection Not Triggering

• Go to Camera Settings → Motion Detection or Smart Event
• Ensure motion detection is enabled for each camera
• Check the detection area — the blue grid should cover the areas where you want to detect motion
• Increase sensitivity if motion is being missed (but too high will cause false alerts)
• Set appropriate target size — very small objects might be filtered out

Too Many False Alerts

• Reduce sensitivity or adjust detection area to exclude trees, roads, and other sources of constant motion
• Enable smart detection if your system supports it — this filters alerts to only humans and vehicles
• Exclude wind-prone areas from the detection zone
• Adjust time-based sensitivity — lower at night when shadows and animals cause false triggers

Step 4: Check Stream Settings

Incorrect stream settings can cause recording failures or poor quality:

• Go to Camera Settings → Video/Stream
• Main stream (recording): Set to full resolution (e.g., 4MP, 2560x1440)
• Sub stream (remote viewing): Lower resolution (e.g., 704x576) to save bandwidth
• Bitrate: Higher bitrate = better quality but more storage used. 4096 kbps is a good default for 4MP
• Frame rate: 15fps is sufficient for security. 25fps provides smoother video but doubles storage use

Storage Calculation Guide

Based on H.265+ compression, continuous recording

Step 5: Playback Issues

If footage is recording but won't play back properly:

• Choppy playback on phone: Switch from main stream to sub stream for remote viewing
• "No video" on playback: The file may be corrupted. Try a different time range
• Timeline shows recording but playback is black: Camera may have been offline during that period. Check the NVR event log
• Export not working: Try exporting in a different format (.mp4 instead of .avi) or via USB drive
• Playback on PC: Use the manufacturer's player software or VLC media player

Summary

Recording issues almost always trace back to the hard drive, recording schedule, or motion detection configuration. Check the HDD first — it's the single most common point of failure. Ensure your schedule matches your expectations, and if using motion recording, verify that detection zones and sensitivity are properly configured. A well-configured system should record reliably for years without intervention.
