Check live view, then a recorded test event, then phone notifications. If live view works but no clip appears, check detection settings and storage. If a clip exists, troubleshoot alerts. Test battery cameras with live view closed so you also check wake-up behavior.

These examples show why power and storage arrangements matter. Work through the checks below before replacing a camera; a different model still needs the right settings.

Research checked October 13, 2026. This guide uses manufacturer documentation, not hands-on detection testing.

1. Identify what is actually missing

Start with a fresh live view, rather than an old thumbnail. Confirm that the picture changes when someone moves. Then note the time, walk through the area you want protected, and look in event history and the appropriate recording timeline. Finally, check whether the phone received an alert.

• No working live view: check power or battery, connection and privacy mode before adjusting detection.
• Live view works, but no motion event or clip: investigate detection controls and the recording path separately.
• A playable motion clip exists, but no alert: begin with notification settings.
• An alert arrives, but no playable clip: allow an in-progress clip to finish and refresh history first. If it is still missing, inspect storage, recording permission, schedule and the selected playback destination.
• Only part of the visit is recorded: inspect wake-up coverage, clip length and retrigger behavior.

This is a diagnostic order, not a claim that every brand has identical controls. TP-Link’s detection guide, for example, treats event detection, recording, notifications and alarms as distinct settings. A successful live stream alone does not verify all of them. For connection-specific problems, see what security cameras can do without internet.

2. Check the active mode, privacy setting and schedules

Confirm that motion detection is enabled for this camera and that its current Home, Away, armed or custom mode permits the action you want. A mode may allow detection but disable recording or push alerts. eufy specifically tells owners of covered eufyCam models to check both Video Record and Push Notification in the selected security mode. See eufy’s mode checks.

Check privacy mode before assuming a hardware fault. On Tapo and Kasa cameras, Privacy Mode stops audio/video streaming and recording. Only turn it off when you intend the camera to monitor the area. See TP-Link’s Privacy Mode explanation.

Next, inspect detection, recording and notification schedules individually wherever your model offers them. For supported Tapo models, the recording schedule can contain continuous-recording, detection-recording or no-recording periods. A blank period can explain missing footage even with detection enabled. Check the correct weekday and compare the camera’s displayed time with the time of your test. See the recording schedule guide.

3. Simplify detection types and activity zones

A person-only filter is designed to ignore activity that the camera does not classify as a person. Temporarily choosing general motion, if supported, helps distinguish a basic detection problem from a classification problem. Keep a note of the original setting and restore the categories you want after testing. eufy’s SoloCam guidance identifies human-only filtering, low sensitivity and restrictive activity zones as possible causes of missed activity. See eufy’s missed-motion troubleshooting.

Inspect the zone preview carefully. Some apps let you draw an included area; others let you select excluded areas. In Blink’s grid, selected gray squares are inactive. Refresh the preview after moving a camera so the drawing matches its current view. Do not confuse an activity zone with a privacy zone: on supported Blink models, privacy zones mask areas from recording. See Blink’s zone definitions.

For a controlled test, broaden only the detection area covering your own approach route. Preserve any privacy masking that protects other people. If a broad zone works, narrow it gradually while repeating the same walk. This tells you where the filter begins excluding useful activity without changing several variables at once.

4. Match sensitivity and positioning to the detector

PIR detection responds to changes in infrared heat energy. Image-based detection compares changes between video frames. Many cameras combine a wake-up sensor with further image analysis, so seeing a person clearly in live view does not prove the sleeping camera can detect that person at the same distance. The model’s documented detection range matters more than how far its lens can see. See TP-Link’s detector explanation.

For a PIR-equipped camera, try a route that crosses the view as well as one directly toward the lens. Blink explains that PIR is more sensitive to movement across the field of view. Follow your exact model’s mounting instructions; a recommended height or angle for one camera is not a universal installation rule. See Blink’s motion-detection guidance.

Raise sensitivity in small steps and repeat the same route. The useful setting is the one that detects the approach you need without producing an unacceptable stream of irrelevant events. If the app offers a motion-test mode, check whether its test settings carry over. eufy warns that its Motion Test Mode sensitivity value does not automatically become the normal detection setting. See eufy’s sensitivity instructions.

If the camera sits behind glass, treat that as a separate installation issue. Reflections and infrared glare can interfere with image analysis; PIR-based outdoor detection has additional limitations. Use our security camera through a window guide. If misses happen only after dark, repeat the route at night and inspect the actual image using the night-vision troubleshooting guide.

5. Test battery wake-up and gaps between clips

Close live view before testing a battery camera’s normal standby behavior. TP-Link documents that many of its battery cameras wake either from their PIR sensor or from opening the live stream. A camera that records only while you watch it may have a wake-up coverage problem. Allow it to return to standby using the model’s guidance, then approach again. See TP-Link’s battery-camera diagnostic sequence.

Also distinguish a late first clip from a missing second clip. Check the configured retrigger or cooldown interval and wait beyond it before repeating the test. Blink states that motion events are not recorded during its retrigger interval. Available intervals differ by model. Longer clips, post-motion buffers and shorter retrigger delays may help where supported, but review the associated battery trade-offs in your camera’s documentation. See Blink’s retrigger explanation.

If your requirement is an unbroken record of a busy approach, confirm the exact camera, power arrangement and storage support that requirement. Our continuous-recording guide explains that decision in more detail.

6. Verify that the event has somewhere to be saved

Open the storage status page. Look for a recognized, healthy card or hub drive, enabled local recording, and enough usable storage or the intended overwrite setting. For cloud recording, check that the correct camera has an active plan and that you are viewing cloud history rather than the local timeline. Buying a plan is unnecessary if your model already supports the local recording arrangement you need.

Use the exact model’s storage requirements. Tapo’s compatibility guidance notes that capacity support varies by model and hardware version. Its Loop Recording feature replaces older footage when the card fills, so download anything important before it is overwritten. See Tapo’s card compatibility and overwrite guidance.

Do not format the card as your first experiment. Back up needed clips first: formatting or initialization can erase them. Follow the manufacturer’s card-fault procedure and try a known-compatible card if appropriate. TP-Link’s official card troubleshooting also calls for backing up important files before initialization.

7. Fix phone alerts only after checking the event

If a motion clip exists, confirm alerts are enabled for that camera and event category in the camera app. Then inspect the phone’s app notification permission, Focus or Do Not Disturb behavior, and any notification schedule. On Android, background battery restrictions can delay alerts. Test with a working phone data connection. TP-Link’s current troubleshooting guide covers these separate delivery controls; menu names vary with the phone and operating system. See TP-Link’s notification troubleshooting.

Keep the timestamp of the saved clip and the time the alert arrived. A delayed alert and a missing recording are different symptoms, and that small record helps avoid repeating the wrong fix.

Run one repeatable test before resetting anything

1. Write down the camera model, firmware, active mode and original settings.
2. Choose a normal approach route within the documented detection range.
3. Change one setting, leave live view, and wait through any standby or retrigger interval.
4. Walk the route and note the exact time.
5. Check for a detected event, a playable recording and a phone alert separately.
6. Repeat from the other direction and after dark if those are the conditions that fail.

Update the app and camera firmware through the manufacturer’s supported process, then retest. If the problem persists, contact official support with the model, versions, time-stamped results and relevant settings. TP-Link provides a camera diagnostic-log procedure for persistent problems. Review what a log contains and share it only through the manufacturer’s support channel. Save a factory reset for a documented next step, after preserving footage and setup details.

Frequently asked questions

Why does live view work but motion recording does not?

Live view proves that you can obtain a current picture. Event recording still needs an enabled trigger, an active recording rule and working storage. Check all three. On a sleeping battery model, opening live view can also wake the camera, so repeat your walk with live view closed before deciding its motion sensor is working normally. Detection and recording settings; battery wake-up behavior.

Should I turn motion sensitivity all the way up?

Use a higher setting as a diagnostic step, then tune it to your route. A maximum setting is not a substitute for suitable placement or a correctly drawn zone. If general motion detects you but person-only detection does not, investigate classification and framing before continuing to raise sensitivity. Keep testing after every change rather than assuming a higher number solved the problem. eufy’s detection guidance.

Why are there recordings but no motion notifications?

Recording and push alerts can be controlled separately. Check the camera’s alert switch and event types, any notification schedule, and the phone’s notification permissions. Focus or Do Not Disturb and Android background restrictions can interfere even when the clip saves. Use the clip timestamp to see whether the alert is missing entirely or simply late. TP-Link’s notification checks.

Why does a battery camera miss the start of a visit or a second event?

These symptoms can have different causes. A late first clip calls for checking wake-up coverage and placement. A missed event immediately after a saved clip calls for checking retrigger time. Also inspect supported clip-length and post-motion-buffer settings. Do not copy another brand’s timing values: use your model’s available controls and verify the result with repeated walks. TP-Link’s battery and clip-setting checks.

Do I need a subscription to fix missing motion recordings?

Only if the recording feature you intend to use requires one. Supported local storage can save events without a cloud plan; the Tapo C120 and SoloCam E30 both document local-storage options. First confirm that storage is installed, recognized and enabled for your setup. A subscription will not correct an excluded detection zone, disabled recording mode or poor camera placement.
