Edge AI security with mobile app alerts
What we built
- A complete security system on a small, low-power AI device
- Face recognition, person detection and intrusion detection on the device
- Alerts sent to a mobile app
What it changed
The models were optimised to process 100 frames per second on an NVIDIA Jetson Nano, so alerts are instant and footage stays on site.

Frequently asked questions
Should we build native or cross-platform?
Cross-platform suits most business apps and means one codebase to maintain. Native is better when the app relies heavily on device hardware or needs the smoothest possible performance. We recommend one after understanding your app.
Do you handle App Store and Google Play publishing?
Yes. We prepare the listing, screenshots and privacy details, submit the app and respond to reviewer questions. The app is published under your own developer account so you keep control of it.
How is the cost decided?
It depends on the number of screens, platforms, integrations and back-end work. We agree a price after discovery, and often suggest a smaller first release so you can learn from real users before adding more.
Will the app need updates after launch?
Yes. Apple and Google release new operating system versions every year, and apps need testing and updates to keep working. We offer support arrangements that cover this along with fixes and new features.
