IVSEC KIT IVK-28E
All you need for a quality video surveillance solution is in this box:

• 5 Mega-pixel high resolution
• Built-in PIR sensor can trigger recording
• Most cameras can only record on movement detection, but this creates a lot of unnecessary recording with moving branches or vehicle headlights. With this kit, you have the choice of using motion detection and/or the built-in PIR sensor to trigger recording. This can save a huge amount of storage and makes it faster to find the events which really matter.
