Spotter. From $50

While you are out and about, you might want to keep an eye on what’s going on back home.

That’s where Spotter can help. This multipurpose sensor can monitor motion, sound, light, temperature, and humidity all from your mobile device.

It connects to your wifi network, but can use either mains power or batteries, meaning you can put the sensor almost anywhere, provided there is wifi coverage.

It's still in its early days, which means the accompanying app is a little limited, but Spotter could be one to watch for the future.
