D-Link Omna Camera
The D-Link Omna is one of the first HomeKit compatible security cameras. The 180-degree wide-angle lens can capture an entire room using just a single camera (at full HD 1080p resolution). It has night vision of to 16 feet. You can also access the Omna 180 Cam HD directly from the Home app on your iPhone or iPad, so you don't even need another app to manage. It records directly to a SD-Card, so it doesn't slow down your internet when it's recording 1080P footage.
You can buy it at the Apple Store for $149.95
