How to Stop Your Security Camera Sending Useless Alerts
The fastest way to stop using a security camera is to let it send you forty notifications a day. Within a week you swipe them away without reading, and the camera has become decorative. Here is how to fix that in under half an hour.
Shrink the detection zone first
Most false alerts come from movement you never cared about: traffic, pedestrians, next door's washing line. Redraw the zone so it covers only your property and only the approach path.
A tight zone with high sensitivity beats a wide zone with low sensitivity. The former misses less that matters; the latter misses people walking slowly.
Turn on person detection if you have it
Cameras with on-device person filtering discard most animal and foliage triggers before a notification is sent. If it is available without a subscription, enable it immediately.
If it is subscription-locked, decide whether the fee is worth it before buying the camera, not after.
Deal with insects and infrared
Infrared LEDs attract moths, and a moth two inches from the lens looks like a large fast object. Symptoms: a cluster of alerts between dusk and midnight in summer.
Fixes that work: switch that camera to colour night mode with a nearby light source, move the unit away from other bright lamps, and clean the lens ring — dust scatters IR and makes the problem worse.
Use schedules and geofencing
Indoor cameras should generally not alert while you are home. Geofencing arms them when the last phone leaves and disarms on arrival.
For outdoor positions, keep recording on all day but restrict push notifications to the hours you actually want interrupting.
Fix the physical causes
Trim the branch. Move the wind chime. Angle the camera a few degrees away from the reflective car bonnet. Physical fixes are permanent; software tuning is a patch over them.
Heat vents and tumble-dryer outlets can also trigger PIR-based detection on cold days.
Keep firmware current
Detection algorithms genuinely improve over updates, and a lot of camera complaints online refer to firmware that has since been superseded.
Check for an update monthly, and after any change re-test by walking your own approach path at night before assuming it works.
