2.2 Initial Setup Steps
- Install Batteries: Open the battery compartment on each Blink camera and insert the two included AA Lithium 1.5V non-rechargeable batteries.
- Connect Sync Module: Plug the Sync Module into a power outlet using the provided power adapter and USB cable. Wait for the Sync Module to power on and its indicator lights to show readiness. If a red light appears, a reset may be required by inserting a pin into the reset hole.
- Download Blink App: Download and install the "Blink Home Monitor" app from the Apple App Store (for iOS 10.3 or higher) or Google Play Store (for Android 5 Lollipop or higher) on your smartphone or tablet.
- Create Account: Open the Blink app and follow the on-screen instructions to create a new account or log in to an existing one.

- Add Cameras: Follow the app's instructions to add each Blink camera to your system. This typically involves scanning a QR code or entering a serial number.
2.3 Camera Placement Guidelines
Optimal camera placement is crucial for effective monitoring. Consider the following:
- Height: Position cameras at eye level for clearer facial recognition.
- Lighting: Place cameras in well-illuminated areas. Avoid pointing directly at brightly lit windows, as this can cause subjects in front of the window to appear as silhouettes.
- Wi-Fi Range: Ensure cameras are within good Wi-Fi range of your Sync Module, and the Sync Module is within good range of your home Wi-Fi access point.
- Field of View: The camera lens covers approximately 110 degrees. Plan placement to cover desired areas effectively.

3. Operating the System
The Blink system is designed for ease of use, providing real-time monitoring and alerts through its dedicated mobile application.
3.1 Motion Detection and Alerts
- The built-in motion sensor triggers recording when movement is detected.
- Upon detection, the cameras send an alert to your smartphone and record a short video clip to the cloud.
- Recorded clips are typically up to 10 seconds in length.
- The camera features a blue LED light that illuminates during recording. This is an intentional design feature to indicate when the camera is active.
3.2 Live View Streaming
Utilize the "Live View" streaming mode within the Blink app to monitor your home or pets in real time. This feature provides immediate visual access to your camera feeds.
3.3 Cloud Storage
The Blink system includes free cloud storage for your recorded video clips, eliminating the need for monthly fees or service contracts.
3.4 App Control and Alexa Integration
- Control your wireless cameras using the Blink Home Monitor app on your iOS or Android device.
- The system is compatible with Amazon Alexa. Use select Alexa-enabled devices to view live streams, motion clips, arm and disarm your system, and manage battery reorders.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Blink system.
4.1 Battery Replacement
- Blink cameras are powered by two AA Lithium 1.5V non-rechargeable batteries, offering up to two years of battery life under typical usage.
- Monitor battery status through the Blink Home Monitor app.
- When batteries are low, replace them with new AA Lithium 1.5V non-rechargeable batteries. Do not use rechargeable batteries.
4.2 Cleaning
Gently wipe the camera lens and body with a soft, dry cloth to remove dust and smudges. Avoid using harsh chemicals or abrasive materials.
4.3 Firmware Updates
The Blink system may receive automatic firmware updates to improve performance and add new features. Ensure your Sync Module is connected to the internet to receive these updates.
5. Troubleshooting
This section addresses common issues you might encounter with your Blink Indoor Home Security Camera System.
5.1 Sync Module Issues
- Red Light Indicator: If your Sync Module displays a red light, it may indicate a connection issue. Try resetting the module by gently pressing a pin into the reset hole.
- No Connection: Ensure the Sync Module is within range of your Wi-Fi router and has a stable power supply.
5.2 Camera Connection and Pairing
- Pairing Difficulties: When entering camera identifier numbers in the app, ensure each digit is pressed slowly and deliberately to avoid input errors.
- Camera Offline: Check the camera's batteries. Ensure the camera is within range of the Sync Module.
5.3 Motion Detection and Video Quality
- False Alerts: Adjust the motion detection sensitivity settings within the Blink app. High sensitivity can trigger alerts from minor movements like passing cars or waving leaves.
- Poor Video Quality in Low Light: Blink cameras lack night vision. For dark rooms, you can enable the camera's built-in illuminator, though this will make the camera more visible. Ensure the area is adequately lit for optimal video.
- Notification Issues: If you are not receiving notifications, check your smartphone's app notification settings and ensure they are enabled for the Blink Home Monitor app.
