You want to look in on your living room from work without adding another camera to the shelf. This Blu-ray player keeps playing your discs and carries a 720p camera behind its front panel.

• Sits with your TV: a working Blu-ray player whose front panel holds the camera and motion sensor.
• See and hear the room: 1280 × 720 video with audio across a 125° field of view.
• Records when something moves: its motion sensor starts recording and keeps false alerts down.
• About 32 hours on the card: the included 32 GB card keeps recordings on the player itself.

What you need: a 120 V, 60 Hz outlet, your home Wi-Fi network, and a smartphone or tablet with the app.

Good to know: the app asks for a login, and the camera doesn't broadcast its Wi-Fi network name.

Using it: check that the dog has settled after you leave for the day.
