Camera Viewer: Home CCTV

Turn the phones you already have into home cameras.

One phone becomes a CAMERA: it records video with sound into its own memory and hands the live picture over your Wi-Fi. Another phone — or a Windows PC — becomes the RECEIVER: it finds the cameras on the network, watches them live and rewinds back in time whenever you want, the way a DVR does.

NO CLOUD, NO SERVER, NO ACCOUNT
Everything lives on your own devices and travels straight across your home network. The app needs no internet connection and never asks you to sign in. The price of that is worth knowing before you install: the cameras are reachable only from inside your own Wi-Fi network.

CAMERA
• Continuous recording, in MP4 segments of 15 seconds
• The date and time are burned into the frame itself — into the recording, not only into the preview
• Live picture up to 30 frames per second
• Recording only while something moves, when you want the files to grow slower
• Event log: when the capture started, stopped, or the phone rebooted
• Keeps working in the background and with the screen off

RECEIVER
• The cameras as tiles, with live thumbnails
• Live view with sound
• Continuous rewind along a real-time scale — to any moment the camera still keeps
• The wall: every camera at once, and a rewind of all of them to one and the same moment
• Downloading the whole archive from a camera onto the phone
• Background watch: an alert when a camera disappears from the network

HEAT IS TREATED AS SAFETY
A camera can work for days without anybody looking at it, so the app measures the phone’s own temperature all the time. When it gets too hot, the capture rate goes down by itself — and the capture stops completely if that is not enough.

WHAT YOU NEED
• Two devices: one for the camera, one for the receiver
• Both on the same Wi-Fi network
• Android 7.0 or newer

WHY THESE PERMISSIONS
• Camera and microphone — the capture itself. Nothing is uploaded anywhere: the recording stays in the phone’s own memory until you download it yourself.
• Notifications — the capture notice, which stays in the status bar while filming, and the “a camera is gone” alert.
• Start at boot — not to start filming behind your back (Android does not allow that), but to say out loud that filming is NOT running after a restart. Otherwise you learn about a lost night when you come to watch it.

There are no accounts and no analytics in the app.
