Having problems getting your Blink cameras to reliably detect motion and send alerts? Motion detection is one of the most important features of an indoor/outdoor home security camera. But sometimes finicky sensors, incorrect camera settings, and Wi-Fi problems can cause blink camera motion detection failure.
If your blink camera is not detecting motion then don’t worry! In this guide, we’ll explore the top reasons your Blink camera isn’t picking up movement and provide fixes to get motion-sensing working properly again.
With a few configuration tweaks and camera placement adjustments, you’ll be back to receiving timely motion alerts.

Don’t Place Your Camera Behind Glass
One of the most common reasons your Blink camera stops detecting motion is suboptimal placement behind glass. Windows, plexiglass enclosures, and other glass barriers block infrared motion sensors from properly observing movement.
For best results, mount your Blink camera on a wall or ceiling without any glass in between the camera and detection area. The sensors need an unobstructed view to pick up heat signatures and motion.
If you must place your Blink camera behind a window, thoroughly clean the glass and try to remove any tints or films that could interfere with infrared sensing. Position the camera close to the window pane to limit obstructions.
Also, check for any rapidly changing light conditions like sunshine glare that could overwhelm the camera sensor when placed behind glass. Consider relocating the camera to an area without sun exposure.
Arm Your Blink System
Blink cameras have an “Armed” and “Disarmed” mode. When your system is disarmed, motion detection and alerts are disabled. If you’ve recently changed your Arming settings, this often results in Blink cameras ignoring motion.
Open the Blink app and make sure both your individual cameras and the overall system are set to “Armed”. This activates motion detection. When disarmed, the camera sensors essentially turn off.
You can also set schedules for automatic arming and disarming. Just be aware that outside your armed time windows, the Blink cameras will not detect movement or trigger recordings. Adjust schedules if needed.
Turn on Motion Detection
While Blink cameras automatically have motion detection enabled out of the box, occasionally settings can get changed accidentally.
Open your camera settings in the Blink app and verify the “Motion Detection” setting is toggled on. If it’s off, no motion alerts will trigger. Make sure motion detection is on for each individual camera.
Also, check that motion detection didn’t get set to “Only During Armed” which means it’s inactive when disarmed. Choose “Always” instead.
Adjust The Retrigger Time
Blink has a setting called “retrigger time” which impacts how frequently motion alerts can be triggered. If this is set too high, you may miss motion events.
For example, a retrigger time of 60 seconds means that after a motion alert is triggered, Blink will ignore any additional motion for the next 60 seconds. Any movement during that period won’t be detected.
For the most sensitive detection, set your retrigger time lower, between 5-15 seconds. This allows motion to be continually detected. Just keep in mind more alerts will be generated.
Change Your Activity Zones
Blink cameras allow you to define specific “activity zones” where it will detect motion. If your motion detection issues coincide with a recent zone change, this could be the culprit.
Open the camera in the Blink app and select motion settings. Review the activity zones and make sure motion detection is enabled for the areas you want to be monitored. The rest of the camera frame can be excluded.
Zones are handy for eliminating false positives from high-traffic areas. But make sure you haven’t accidentally restricted the motion zones too much, preventing real motion from being detected.
Configure Your Camera’s Sensitivity
Another setting that impacts motion detection accuracy is your camera’s overall motion sensitivity. This can be set to Low, Medium, or High.
A higher sensitivity level makes your camera more responsive to small movements and heat signatures at greater distances. But it can also increase false motion triggers.
Try setting your Blink camera to a higher sensitivity level like High to rule out sensitivity as the cause of your motion detection issues. Just remember to tweak it back down if you start getting too many irrelevant motion alerts.
Turn on Motion Recording
In the Blink settings you have the option to disable video recordings for motion alerts and only receive notifications. Make sure motion-triggered recording is enabled.
Without recordings, motion events simply disappear after notification. You won’t have any video evidence to review later – making motion detection pointless.
Double-check check this setting hadn’t accidentally been switched off. With motion recordings enabled, all detected activity will be captured.
Change Your Night Vision Settings
Most motion detection problems with Blink cameras arise at night when using infrared night vision. IR motion sensing can be tricky.
Try switching your Blink camera night vision mode from “Auto” to “On”. This forces night vision IR to remain continually active versus regularly toggling on/off. Consistent IR illumination often improves motion detection.
Also check that any external lights aren’t overpowering the IR sensors at night. Consider motion sensor lights to provide illumination only when needed.
Replace Your Blink Camera Batteries
For Blink battery-powered cameras, worn-out batteries are a common source of motion detection failures, especially at night when more power is demanded.
If your camera worked better when new, but now misses motion events, try changing blink batteries. Avoid cheaper generic batteries with lower power output.
Even with fresh batteries, cold weather conditions can drain power faster. Maintain spare sets of batteries on hand for easy replacements.
Check Your Wi-Fi Connection
Finally, spotty Wi-Fi connectivity issues can manifest as motion detection failures. Without consistent data transfer between your camera and the Blink servers, motion alerts can’t be delivered.
Verify your Blink camera has at least two Wi-Fi signal strength bars in the app. Relocate the camera closer to your router if needed. Also, minimize radio interference from other wireless devices.
For battery cameras, position the sync module central to your camera’s location and confirm it’s plugged in. Check for any firmware updates that could resolve Wi-Fi bugs. Reliable wireless connections are critical.
Having your Blink camera fail to detect motion can completely defeat its security purpose. But in most cases, intermittent or total motion detection failure can be resolved with troubleshooting.
Review your camera placement and remove obstructions, adjust key sensitivity and motion settings, force night vision on, and rule out Wi-Fi dead zones. With tuned camera configurations and optimal locations, you’ll restore trust in your Blink camera’s motion alerts.
Frequently Asked Questions
Still, have questions about resolving Blink camera motion detection problems? Here are some key FAQs:
Why did my Blink camera suddenly stop detecting motion?
This often occurs when batteries run low, the camera gets obstructed, motion zones change, Wi-Fi signal drops, or sensitivity settings reduce. Check these potential issues first.
How can I make my Blink camera more sensitive to motion?
Open your Blink camera settings and turn up the motion detection sensitivity to High. Also, lower the retrigger time. This will make small movements easier to detect.
Why doesn’t my Blink camera detect motion at night?
Night motion sensing uses IR sensors which can struggle in pitch-black conditions. Make sure night vision is on and add supplemental lighting if needed. Also, replace low batteries.
Do Blink cameras detect motion through glass?
No, placing Blink cameras behind glass, plexiglass, or windows will significantly impair motion detection performance, especially at night. Avoid glass barriers where possible.
How do I stop false motion alerts on my Blink?
Adjust your camera’s motion sensitivity lower, increase the retrigger time, and limit activity zones to high-traffic areas. This will reduce bogus motion triggers from minor disturbances.
