OPERATION MODES

Video Mode

Video/Photo Playback Mode

Photo Playback mode

VIDEO MODE

Video Mode is the default mode for the device, and allows you to easily record HD video of the road ahead of you.

When first powered on, the device will start in video mode and automatically begin recording. To start/stop recording press the Record/Pause button.

Continuous Loop Recording: Once the memory card is full, the camera will continuously overwrite the oldest footage recorded. To protect a clip so that it will not be overwritten, press the Emergency Record button. The emergency record icon will show on the screen. Files can also be locked from the playback menu in Video Playback Mode.

G-Sensor: The G-Sensor is an accelerometer that can detect an impact caused by an accident. If the G-Sensor is triggered, the current video segment will automatically be locked so that it is not overwritten by continuous loop recording.

Note: Setting proper G-Sensor sensitivity is important for proper operation of the product. If the G-Sensor is too sensitive it will unnecessarily lock files and can result in the memory card filling up quickly. If it's not sensitive enough, then it may not lock a file in the event of a legitimate collision.

Shortcuts: While in video mode, you can perform these functions

- Menu enters the settings menu to change the video settings, general settings, iRadar app settings (CDR 855 BT only), and language settings.

Note: This option is only available when the camera is not recording.

• Screen on/off turns the LCD screen off. The device will continue recording while the screen is blank.
• Playback enters the playback menu to review previous recordings and photos. Note: this menu can only be selected when the camera is not recording.
• Microphone Toggle turns the microphone on or off. The current setting is shown at the top of the video screen.
• Snapshot takes a snapshot/photo. The unit does not have to be recording in order to take a snapshot
  • Record/Pause starts or pauses a recording

VIDEO SETTINGS

Video resolution:

This setting allows you to set one of three available video recording resolutions:

Higher resolutions will give you a sharper image, but take up more memory on the card.

The available resolutions are:

1080P Full HD 1920x1080 30 Frames per Second

720P HD 60fps 1280x720 60 Frames per Second

720P HD 30fps 1280x720 30 Frames per Second

Capacity

This setting allows you to control the duration of each individual movie clip on the device.

Movie clips can be set to durations of 3 minutes, 5 minutes, or 10 minutes or Action Cam Mode. Turning the loop clip time to Action Cam Mode lets the device record one uninterrupted movie clip, but disables continuous loop recording.

G-Sensor:

The Drive HD Dash Cam includes a built in G-Sensor which allows the device to determine when the car has been in a collision. If it detects a collision, it automatically locks the recording being made at the time of the accident. You can use this setting to set the sensitivity of the G-Sensor from 1-3 or turn it off. Level 1 is the easiest to activate the G-sensor and the G-Sensor may lock files due to smaller bumps like potholes and the SD card may fill up with protected files. Level 3 is the hardest to activate the G-sensor.

Parking Mode:

Enabling this setting will allow the device to enter parking mode if no motion is detected for 5 or 10 minutes while the camera is recording. The recording will restart when motion is detected. The default setting is 10 minutes.

Cobra Watermark, Date/Time Stamp, & Time Stamp Format:

These menu options change the watermark & time stamp that will appear on the saved video files. Photo files do not contain a watermark.

GENERAL SETTINGS

Volume:

Allows you to raise and lower the volume of sound playback on the device.

Date/Time:

Allows you to set the date and time on the device and for use with the timestamp.

Screen Saver:

Allows you to set a duration after which the device's display will go dark. This setting is useful to avoid distracted driving and having a bright LED screen when driving at night. Select 1 minute or 3 minutes.

Beep Sound:

Turns the sound on or off for each time a button is pressed. Note: this only effects normal button presses. Alerts to the user of errors, or iRadar sounds (CDR855BT only) are not effected by this setting.

Format SD Card:

Allows you to format the inserted SD Card. NOTE: This action will permanently delete all data on the card.

Restore Defaults:

Resets the device to factory settings. Note that restoring defaults will NOT erase data on your memory card.

Displays the device software version.
