HomeCam TV
Your Dahua NVR on the television, driven entirely by the remote.
Four screens, no menus.
Camera wall
Every camera at once, 1×1 / 2×2 / 3×3. Select one for fullscreen.
Recorded playback
Scrub a 24-hour timeline of the recorder's own archive to any moment.
Status
Whether everything is actually recording, and which stream each camera is on.
Channel up / down
Changes camera. In playback it keeps the time, so 18:05 on camera 1 becomes 18:05 on camera 2.
Self-configuring
Asks the recorder for its channels and uses its names. Nothing about the setup is compiled in.
The hard part is the d-pad.
Most camera apps on a television are phone apps with a TV manifest entry. Focus lands nowhere, controls can't be reached, and text is sized for arm's length.
Every screen here names the control it opens on, so the remote never goes dead. Up out of a page returns to the tab you were on. Anything at a screen edge names its vertical neighbour rather than trusting geometry — because focus search only considers what sits inside its beam, and a right-aligned button with nothing above it finds nothing at all.
It also notices when a camera's sub-stream returns audio and no picture — a real fault on real hardware — and quietly falls back to the main stream for that channel.
