Why Won't My Blink Doorbell Send Motion Alerts?
- System disarmed (doorbell rings but no motion alerts)
- Motion detection disabled for the doorbell
- Sensitivity set too low
Problem Description
Your Blink video doorbell is not sending motion alerts to your phone. Blink doorbells only send motion alerts when the system is armed. If the system is disarmed, the doorbell still rings but does not trigger motion notifications. This guide covers arming the system, checking notification permissions on your phone, and adjusting motion sensitivity.
Why This Happens in Real Homes
The behavior that confuses people most about the Blink Video Doorbell is that it treats the button press and motion alerts differently: the doorbell will still chime when someone presses the button even if the system is disarmed, but it only sends motion notifications when the system is armed. So 'the doorbell rings but I get no motion alerts' almost always means the system is disarmed - arming it restores motion notifications immediately. Confirm motion detection is enabled for the doorbell specifically as well.
Once arming and detection are on, the usual motion tuning applies. Sensitivity set too low, or activity zones drawn too tight, cause the doorbell to miss people walking up - raising sensitivity and expanding the zones to cover the approach path fixes most missed events. Don't overlook the phone side: if notifications are blocked for the Blink app in your phone's settings, the alerts are being generated but never shown, so check notification permissions. Late alerts point to a weak WiFi link to the Sync Module, a low battery, or occasionally Blink server delays. And because the doorbell uses PIR motion, aiming it so visitors cross its field of view rather than approach head-on improves how reliably it catches them.
Symptoms
- No motion alerts on your phone
- Only get alerts for the button press
- Alerts arrive minutes late
- Motion detection turned itself off
- Doorbell rings but no motion notification
- Alerts stopped after disarming
- Some motion missed entirely
- Notifications inconsistent
Recognize these? Here's what usually causes it.
Common Causes
- System disarmed (doorbell rings but no motion alerts)
- Motion detection disabled for the doorbell
- Sensitivity set too low
- Activity zones too small/excluding the walkway
- Phone notifications blocked for the Blink app
- Blink server or upload delay
- Battery low or weak WiFi to the Sync Module
- PIR aimed poorly for the approach
Most fixes happen in the first 3 steps.
Motion alerts and button press alerts are separate settings. Enable both for complete coverage.

Step-by-Step Solution
Check if the system is armed
Blink cameras and doorbells only send motion alerts when the system is Armed. In the Blink app, check the arm/disarm status for the system the doorbell belongs to. Tap the running person icon to arm. When disarmed, the doorbell does not send motion notifications (but still sends ring notifications when someone presses the button). This is by design — disarm when home to avoid constant alerts.
Verify motion detection is enabled for the doorbell
In the Blink app, tap the doorbell > Settings > Motion Detection. Make sure the toggle is on. Even when the system is armed, individual devices can have motion detection disabled. Also check the Motion Sensitivity slider — a very low setting may miss people at distance.
Check notification permissions on your phone
On iPhone: Settings > Notifications > Blink. Make sure Allow Notifications is on, Banners is enabled, and Sounds is on. On Android: Settings > Apps > Blink > Notifications. Check that all notification channels are enabled. Also check that Do Not Disturb is not silencing Blink alerts.
Adjust motion sensitivity and retrigger time
In the doorbell settings, increase Motion Sensitivity if alerts are not triggering. Also check the Retrigger Time — this is the cooldown period between motion clips. If set to 30 seconds, the doorbell ignores all motion for 30 seconds after each trigger. For a busy front porch, set retrigger to 10-15 seconds so you do not miss consecutive visitors.
Check the motion detection zone
In the Blink app, tap the doorbell > Settings > Motion Zones. The zone grid shows which areas are active for detection. Make sure zones covering your walkway and porch are enabled. Disabled zones (dimmed) do not trigger alerts. A known problem: only the far zone is enabled while the close zones (where people actually stand) are disabled.
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.
Blink uses AWS cloud for notifications. During AWS outages, all Blink alerts may be delayed.
Notification delays over 2 minutes are almost never the device's fault — background app restrictions quietly re-enable themselves after every OS update.
