When Early Notification is enabled, the camera sends the alert when motion is first detected.

When Early Notification is not enabled, Motion Alerts are sent after the Motion Clip is saved.

The amount of time 'earlier' you receive an Early Notification depends upon your Clip Length settings and other factors like network speeds.

The Early Notification option is only available for the following Blink devices:

• Blink Outdoor and Indoor (3rd Gen)
• Mini
• XT2

Early Notification is enabled by default and can't be turned off on the Blink Outdoor 4, Wired Floodlight and Video Doorbell.

Why would I use Early Notification?

A real advantage of Early Notification is being able to enter Live View if you tap the Motion Alert notification, when you're within the time frame of that clip length, or five seconds after. In this way, you can be interacting with visitors using two-way voice, or viewing whatever triggered the motion alert, within a few seconds of receiving your notification.

Note: If you pass the five second time frame after the clip has ended, you will be automatically taken to the clip list screen with no clip selected.

Can I save the Live View session?

If you have an active Blink Subscription Plan‍ and your camera supports recording the Live View session, a "Save / Discard " toggle appears in the live view. When the toggle is set to "Save", the current session records until the timeout, or when you stop the Live View by tapping "Close".

How do I use Early Notification?

To enable Early Notification, go to the camera settings screen and select Motion Settings. Then switch on Early Notification.

Early Notification is off by default for Blink cameras, as shown in the image.

This article describes how to adjust the retrigger time for your Blink camera. 

Retrigger time is the amount of time between the end a motion capture and beginning of a new motion event. During the retrigger time, your camera does not record motion events. 

By default, the system will capture a five second clip, and wait for the retrigger time of 30 seconds. If motion continues, the camera will capture another five second clip. Retrigger time can be adjusted under Device Settings.

Note: Each camera in your system has an individual retrigger time setting.

Adjusting the Retrigger time

1. Tap Device Settings next to the camera you would like to adjust and select Motion Settings.
2. In Motion Settings, you can adjust the Retrigger time value from 10 to 60 seconds. To increase the retrigger time, move the slider to the right and to decrease the delay move the slider to the left.
   • The longer the retrigger time is set, the longer you camera is not recording between motion events. This is useful if your camera views an area where motion occurs often or if you are getting false motion notifications. 
3. When you have this setting where you want it, tap Save.

Test your setting
After your camera's retrigger time is set, Arm your Blink system and walk through the camera's field of view. You'll receive a motion notification on your mobile device. Continue to walk through the camera's field of view to produce a second motion notification. If the retrigger time was too short or too long between captured clips, return to Device Settings and adjust the Retrigger time.

Your Blink camera captures motion based on heat moving across the camera's field. The total size of heat objects and amount of motion together cause a motion event. Your camera's Sensitivity setting adjusts how much input it takes to send you a notification.

Low sensitivity is less responsive, so a larger amount of heat and motion are needed to cause a notification. The highest setting may cause alerts from blowing leaves or even shadows.

If you are receiving too many notifications with nothing interesting, try turning the Sensitivity down two points. If that is effective, test by arming the system, and walking in the field of view when Motion Detection is on, to make sure a human sized object will trigger a notification.

Be careful if you tap the notification and enter Live View with your microphone or speakers on, significantly loud feedback may occur. Tap mute speaker in the upper right corner of the Live View.

Each camera has an individual sensitivity setting. You can find this in the Camera Settings for each camera in your system.

Choosing High or Low Sensitivity

The sensitivity setting on your camera not only depends on what is making the movement, but how long the movement is occurring. 

• High sensitivity means less motion over a shorter period of time will create a notification.
• Low sensitivity means more movement over a longer period of time will create a notification. 

The motion can be a big or small object, or a lot of small objects. Motion detection depends on where the object is in relation to the camera lens. For example, a bird flying close to the camera can be perceived as bigger than the person walking on the sidewalk in the distance. A person walking directly toward the camera will produce less motion than a dog walking left to right across the camera's field of view. It's about the amount of motion that's occurring within the detection zone of the camera and not necessarily how large the object is.

Testing sensitivity for your home camera

1. From the Blink app main screen, tap Settings above the camera thumbnail and then Motion Settings.
2. Then select Motion Sensitivity and move the slider two or three points to the left towards L, for Low. Tap Save to save this setting and walk out of the frame of view of this camera.
3. From the main screen of the Blink app, set your system to Armed to enable Motion Detection.
4. Test the camera sensitivity by introducing movement. 
   • People, packages, and pets are what home cameras are for.  
5. If the sensitivity is not successful, reduce the slider more, save, and try again.
6. If you have adjusted the sensitivity to your liking, proceed to test with a larger moving object, such as yourself. Walk in front of your camera and check to see if the setting gives the desired motion alert.
7. If the lowest sensitivity continues to cause an unwanted Motion notification, you may need to create an Activity Zone instead. Learn more about setting Activity Zones.
