Many homeowners have invested in smart security cameras already. If you are looking for an in-ceiling camera system, you should give the Halo Vantage a look. It screws in like a regular lightbulb but provides you with 1080p video resolution and smart notifications.
The camera has speaker and microphone for 2-way communication. It also has night vision capability. The Halo Home app keeps you connected even when you are away. Expected to ship in July.
