Frequently asked questions
GuardianCam
Do I need to create an account?
No. GuardianCam works without sign-up. The two phones pair with a 6-digit code — that's it.
Is my video uploaded to a server?
No. The live stream goes phone-to-phone via WebRTC. Snapshots and recordings stay on your device — nothing is stored on our servers.
Which devices work?
Any modern phone, tablet or computer with a browser (Chrome, Safari, Edge, Firefox). One device is the Camera, the other is the Monitor.
Does the camera work when the screen is off?
Browsers pause pages when the screen fully locks. Use the Background mode setting to keep the screen awake, or turn on the screen-dim timer to keep filming while the phone looks dark.
How much mobile data does it use?
Roughly 0.3–1.5 GB per hour depending on quality. Prefer Wi-Fi. The Camera warns you when it detects a cellular connection.
How does motion detection work?
The app analyzes the video frame-by-frame on-device. You can pick a sensitivity, a target (people, animals, vehicles, or any movement) and auto-record + push notifications.
What is night vision?
The camera lowers exposure requirements and boosts the image in low light. Auto turns it on at night or when the scene is dark.
Can I protect the camera with a PIN?
Yes. Set a PIN in Settings → Camera lock. Nobody can stop the stream without entering it.
Does two-way audio work?
Yes. The Monitor can talk to the Camera and the Camera's microphone streams back. Toggle the mic/speaker buttons in either view.
How do I reuse an old phone as a camera?
