Wi-Fi only with alerts and Live View
Event Response mode starts automatically when the doorbell has no Sync Module connected and powered wiring is not compatible. When the doorbell is connected to a Sync Module system, or to compatible powered wiring, the doorbell exits Event Response.
In Event Response mode, the Blink Video Doorbell powers all of it's own communications, and batteries drain faster than if the doorbell is connected to a Blink Sync Module or powered wiring from a chime system you already have.
"Event Response" appears on the Blink app home screen as an overlay, shown in the image below. In Event Response, the doorbell is not connected to the internet full time, so you must press the ringer button to complete any Settings or Arm/Disarm action.
When you add a Sync Module after the doorbell has been installed, select the doorbell system when you reach that step. If you complete the Sync Module setup on its own system, the doorbell informs you that it is available for connection.

Event Response mode, by itself, provides motion alerts and doorbell press alerts only. To save video clips when motion is detected or the ringer button is pressed, add the doorbell to a Blink Subscription Plan, or connect to a Sync Module 2 with a recognized USB drive inserted.
On the clip list screen, Doorbell clips are shown with a "Bell" icon indicator, and if you do not have a subscription or Local Storage you see the "Non Media Event" screen indicating that an event happened, but no clip was saved.
Alerts and Notifications
When the doorbell button is pressed, or when the doorbell is "Armed" and motion is detected, you receive alerts in the Blink app. You can tap the alert within 60 seconds to enter a Live View session with two-way talk. To save batteries, the doorbell enters a sleep mode after 60 seconds.
Press Doorbell to Save Changes
In Event Response, you must press the doorbell button to 'check-in' and download any new settings changes. Without a button press, or motion activation event, your doorbell checks-in once every 24 hours to automatically download any new configuration changes.
Photo Capture is available if you have an active Blink Subscription Plan or free trial. Photo Capture stores a photo every hour, and if there are no other events, it puts them together into a compressed-time video you can see in the Blink app's clip list. When a motion event or doorbell press does happen, the Photo Capture stops so your notification can get through, and then resumes after. Each time Photo Capture stops, you receive a video of the images taken up to that point.
When the doorbell is in Event Response mode, and a subscription is active, the on-screen thumbnail is updated each time the doorbell ringer button is pressed.
These features are not available in Event Response:
Battery performance is directly related to the amount of use. To improve battery life and gain features, visit Using the Blink Video Doorbell with a Sync Module, or consider connecting your doorbell to an existing chime with Blink Video Doorbell wired installation.
Setting up your doorbell to use Event Response happens automatically when you do not connect to a Sync Module or powered wiring.
After adding the doorbell to your account, you can choose to mount it.
Event Response does not have special mounting instructions.
With a Sync Module 2, you have the option to save clips from the doorbell onto a USB drive as Local Storage without needing a Blink Subscription.
With a Blink Subscription (purchased through Amazon.com) you have a range of features available to cover either one camera or the entire account. Click for more information on Subscription Pricing. In Event Response, without a Sync Module 2 configured for Local Storage, or a subscription, you will not be able to save motion clips, save live views, or receive photocaptures from the camera.
