The built-in GPS capability records the locations you have been as well as tracking your speed, compass heading and speed camera locations as you mark them. No one expects to get into a driving accident, but when it happens, the built-in G-force sensor can detect these events and trigger Emergency Video Recording mode. These emergency recordings are date and time-stamped as well as protected from loop recording oveRWrites. The f800g records video clips of 3 or 5 minute lengths (customer selectable) on to the installed microSDHC memory card. The standard loop recording technology prevents storage overload by erasing the oldest previously recorded file and replacing it with the new one. The small size of the f800g makes it perfect to install without obstructing your view. The small size f800g is equipped with a 140 degree ultra- wide angle lens to capture all the critical elements with little edge to edge distortion. Let the f800g will amaze you with the crystal clear resolution while capturing the vivid colors of the surrounding lights at night. Use the enclosed bracket to install to many windshields in seconds. The car power adapter has a generous 3.5 meter (11.4 feet) cord that accommodates easy routing in almost any vehicle. Once installed, the f800g automatically begins recording when the vehicle starts and powers down when the vehicle is turned off. The camcorder also offers many easy to use options such as motion detection. With the GPS and LDWS feature enabled and the vehicle moving faster than 50 km/h (~31mph), the f800g uses lane markings on the road to warn you when your vehicle drifts from the current lane. The warning is an audible and visual icon displayed on the camcorder screen. This feature should be treated as a guide only, not a reliable safety mechanism.
