Enterprise-level camera access management through QR code scanning and Android Device Administration — built for secure facilities, corporate environments, and controlled zones.
A complete, multi-layered security system that manages camera access based on physical location through QR code entry and exit scanning.
Scan facility entry QR codes to automatically enroll the device and activate camera lockdown. Works entirely offline once validated.
Scan exit QR codes to instantly restore full camera access and cleanly remove device enrollment from the system.
Uses the Android Device Administration API to disable the camera at the hardware level — not just the app, but the entire hardware stack.
A persistent foreground service monitors foreground apps in real time and blocks any camera application the moment it launches.
Full-screen warning overlays instantly block any attempt to open a camera app, with clear messaging for the user.
Locks are maintained across reboots. The service auto-starts on device boot and restores the previous enrollment state.
Every QR scan is validated in real time against a secure REST API using JWT token authentication with expiration checks.
Requests battery optimization exemption to ensure the security service always runs, even on aggressive battery management systems.
Special compatibility handling for Xiaomi MIUI devices and Android 14+ enhanced permission requirements.
The entire entry-to-exit lifecycle is handled automatically through QR scanning. No complex setup needed by end users.
The app guides users step by step through granting camera, overlay, usage stats, and device admin permissions — with helpful prompts at each stage.
On entering a secure facility, the user scans the entry QR code posted at the gate. The app validates it against the backend and enrolls the device.
Device admin policy disables the camera hardware. A foreground service activates with real-time monitoring and overlay blocking for any camera app.
On exit, scan the exit QR code to validate departure, remove device enrollment, and restore full camera access automatically.

No single mechanism is relied on. CamBlock stacks four independent layers of camera blocking to ensure no gap exists — even across different Android OEMs and firmware versions.
Hardware disable, software monitoring, visual overlay blocking, and usage statistics tracking all work in concert to enforce the policy.
CamBlock requests only the permissions necessary for its security functions. Here's exactly why each one is needed.
