Something moved? You’ll know.
Motion detection and a notification help you check what happened.
Give your old Android a new purpose
An old phone.
A fresh pair of eyes.
Turn an old Android phone into a security camera. Get alerts for different detections and events, and watch the live feed from your main phone.
- Two Android phones
- End-to-end encrypted media
- Stored on your phones

Keep an eye on what matters
Your camera, within reach wherever you are.
See how it started.
Optional PreBuffer keeps the five seconds before a detection.
Open the live feed.
Watch, listen and talk remotely from your main phone.
Your phone’s health matters too.
Battery, temperature and storage: check that your camera is ready to keep watch.
Two phones. A simple setup.
One phone stays there.
The other stays with you.
Install NeuriEye on two compatible Android phones with an Internet connection. The phone that records becomes the “Sentinel”; the one you keep with you is the “Viewer”.
Choose your Sentinel
Install NeuriEye on the phone that will stay in place. Its camera, microphone and sensors become your monitoring station.
Connect your Viewer
Use the same Google account on your main phone. The Sentinel appears automatically and completes the secure connection.
Keep watch from anywhere
Enable detection, open the live feed, review events and stay in control of who has access.
Your home is not data to share
Your videos stay on your devices.
Photos and videos are end-to-end encrypted. Neuribrain coordinates connections and permissions, but does not store your media. Private keys stay on your devices.

Give it a second life
Join the testers, step by step.
Three steps to install the beta. Keep this guide open: Google pages open in another tab.
One Google account for all three steps
Choose the account used in this phone’s Play Store. If Google shows another account, switch accounts before continuing.
Your installation steps
Join the NeuriEye test group
Google opens in a new tab. This page stays here to guide you.
Open the test group ↗On Google Groups, look for:
- The “Testeurs NeuriEye” group.
- The “Join group” button.
- A confirmation window: choose your preferences, then click “Join group” again.
After confirming on Google, return to this NeuriEye tab. Google will not bring you back automatically.
Enable your access to the beta
Using the same Google account, open the test page and agree to become a tester. Joining the group does not replace this step.
Enable my beta access ↗When Google shows “You are a tester”, return here to install the app.
Install NeuriEye on your phones
Open the Play listing with the account used in the first two steps. You can then choose Sentinel or Viewer inside the app.

I cannot see “Join group”
Check that you are signed into the right account and viewing the group’s About page. If you are already a member, go to step 2. If Google only shows “Contact owners”, contact us rather than looking through conversations.
Google is using a different account
Select your account using the Google profile icon. Also check the active Play Store account: it must match the account used to join the group and enable the test.
Google Play says the app is unavailable
Check the account, group membership and test enrollment. Google may take a while to recognize access. Try again later; do not delete your account or a Sentinel to resolve this delay.
The link opens inside another app’s browser
If account selection or opening the Play Store does not work, open this site in your usual browser. Direct links remain available at every step.
This guide cannot read your Google account or verify membership. You choose when to continue. No email address is collected here.
Before you get started
Will my old Android phone work? +
You need two compatible Android phones, Google Play and a reliable network connection. Age alone does not tell you enough: the camera, battery and Android settings matter too. Check compatibility.
Is this already a final release? +
No, this is a closed beta: issues may still occur. Test your setup on site before relying on it. Your feedback helps us improve NeuriEye.
A question or feedback about the app? +
Contact Pat, the creator of the project: [email protected]. Include your Android model and what you observed, without sending private images.
