Why Is My SimpliSafe Video Doorbell Not Detecting Motion or Ringing?
- Motion sensitivity set too low
- Motion detection zones not configured correctly
- Doorbell mounted at wrong angle missing approach path
Problem Description
Your SimpliSafe video doorbell does not detect visitors, fails to send motion alerts, or does not ring when the button is pressed. The video doorbell uses infrared motion detection to identify people approaching and should send notifications when motion is detected in the configured zones. Ring button presses should trigger both the doorbell chime and an app notification. When these features fail you miss visitors and deliveries and lose a key layer of front door security.
Symptoms
- No motion alerts when someone approaches the door
- Doorbell does not ring when button is pressed
- Missed delivery notifications despite packages at door
- Motion sensitivity seems too low or too high
- Doorbell detects cars but not people walking up
- Live view works but no motion recordings saved
Recognize these? Here's what usually causes it.
Common Causes
- Motion sensitivity set too low
- Motion detection zones not configured correctly
- Doorbell mounted at wrong angle missing approach path
- IR motion detection blocked by glass storm door
- WiFi signal too weak for reliable notifications
- App notifications disabled on phone
- Doorbell firmware outdated
- Extreme cold affecting battery and sensors
Most fixes happen in the first 3 steps.
Glass doors and windows block IR motion detection. If your doorbell is behind a glass storm door it will not detect motion reliably regardless of sensitivity settings. The doorbell must have a clear line of sight to the approach path without glass interference.

Step-by-Step Solution
Adjust Motion Sensitivity
Open the SimpliSafe app and go to My System then Cameras then select the video doorbell. Tap Motion Settings. Increase the sensitivity slider toward High. Higher sensitivity detects slower movement and smaller heat signatures at greater distances. Start with medium-high and test. If you get too many false alerts from cars or trees reduce slightly. Save settings after adjustment.

$45.99Configure Motion Detection Zones
In the doorbell motion settings tap Activity Zones. Draw zones covering the walkway and porch area where visitors approach. Exclude areas like the street or sidewalk if they cause false alerts. The doorbell will only detect motion within the configured zones. Ensure the zone extends far enough to catch people before they reach the button.
Check Doorbell Mounting Angle
The video doorbell should be mounted 4 feet above the ground pointing straight out or slightly downward. If mounted too high or angled up it may miss motion at porch level. The IR sensor has a specific detection pattern. Remount the doorbell using the included angle bracket if your door frame requires adjustment. The camera view in the app should show the porch floor and approach path.
Address Glass Storm Door Issues
If you have a glass storm door the IR motion sensor may not detect through the glass properly. The doorbell should be mounted outside any storm door. If the button is behind glass visitors may not see it to press. Consider removing the storm door during testing to verify this is the issue. Some users mount the doorbell beside the door frame to avoid storm door interference.
Verify Ring Button and Chime
If motion works but the ring does not check the doorbell wiring if hardwired or battery level if wireless. Press the button firmly and listen for the indoor chime. In the app go to doorbell settings and verify the chime is enabled. If you have a mechanical chime verify it is compatible or enable the digital chime from the base station. Test the button in the app by watching for the notification.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If the sensor still misses events after repositioning, check whether a scheduled 'home' or 'away' mode is overriding the sensitivity setting silently.
The SimpliSafe video doorbell uses infrared to detect body heat. It works better at night than during hot summer days when ambient temperature approaches body temperature reducing contrast. If detection is worse on hot days this is normal IR behavior. Consider supplementing with an entry sensor on the door for guaranteed detection.
Missed motion events are almost always a zone coverage problem, not hardware failure — zone placement accounts for 90% of these complaints.
- Motion sensitivity set too low
