For extended recording times simply add a Power Magic Ultra B-124X or B-112 battery.
The DR900X-2CH IR supports two Parking Mode options, Motion and Impact Detection, and Time Lapse.
Motion and Impact detection mode uses your cameras image sensor to detect movement, and the inbuilt accelerometer/G-sensor to detect bumps or impacts. To reduce the number of unwanted recordings triggered by motion and movement, the DR900X-2CH IR can specify areas to ignore, eliminating recordings triggered by things like swaying trees, far-away moving objects, etc.
In Time Lapse mode, to reduce the size of the video files and save SD card space, the camera will continuously record at just 1FPS (one frame per second), rather than the standard 30/60 FPS. All event clips however are recorded at full resolution and 30FPS. A standard 32GB microSD card can store over 48hrs of time lapse video at the highest (Extreme) video quality level.
