Settings
Record LED (Covert Mode)
The Red Record LED behavior on the camera can be configured to accommodate your
desired operation. If set to OFF, the LED will not illuminate during a recorded event and
will operate in covert mode.
Settings: Off,
On
[default]
Pre-Event Time
The Pre-Event Time option allows you to set the amount of time for the Pre-Event
buffer. The
FirstVu HD
will buffer the last 1-60 seconds of audio and video so that it will
be appended to the beginning of a record event. If set for 0 seconds, the Pre-Event
function will be disabled.
Enabling Pre-Event will reduce battery life.
Settings: 0-60 seconds
[default = 0 seconds (disabled)]
Record Quality
The Record Quality parameter allows the video compression bit rate to be adjusted.
Digital video is compressed by taking out data that remains constant from each frame
to the next, and only storing data that changes. This allows videos with still backgrounds
to have much smaller file size than they would if the background data was unique in
every single frame.
The bit rate is the number of bits that can be used in one second of video. The higher
the record quality, the higher the bit rate and the size of the event files. The default
setting is “high” for a good mix between video qualities and upload time, but can be
lowered or raised to adjust quality and storage space.
Settings: Standard (2Mbps), Medium (4Mbps),
High (6Mbps)
[default], Super
High (12Mbps)
Record Size
The Record Size parameter allows the video image size to be adjusted from VGA
(standard definition) to 720p (high definition). VGA has a picture size of 640x480 pixels,
whereas 720p has a picture size of 1280x720 pixels. 720p will provide a larger & more
defined video picture, but because of its larger size, will require about 3 times as much
storage space as VGA. Also, the shape of the final video frame will be slightly different,
with 720p being a wider frame (higher width ratio to height).
Settings: VGA (640x480),
720p (1280x720)
[default]
Rotate Video
This setting allows you to configure the
FirstVu HD
to record video rotated 180° so
that the camera may be used in an inverted orientation (upside-down), and have the
resulting video appear in the correct orientation.
Settings:
No (Normal camera orientation)
[default], Yes (rotated 180°)
Mute Switch
The Mute Switch selection allows you to Enable or Disable the Mute Switch on the
FirstVu HD
. If the switch is Disabled, audio recording cannot be manually muted by the
device operator.
Settings: Disabled,
Enabled
[default]
