Ring's Wi-Fi floodlight adds an HD camera into the mix

The Ring Floodlight Cam costs $249 (that's roughly £195 and AU$330 at the current exchange rate).

You can install it yourself, but you need to be familiar with electrical wiring -- this device must be hardwired.

It has a built-in 270-degree motion sensor.

You can use the related Ring app to schedule the two integrated LED floodlights to turn on and off automatically.

Its 140-degree security camera has 1080p high-definition live streaming.
