temperatures. It can take up to several minutes before the screen
temperature reaches the appropriate operating range.
In order to create an ultra clear - high resolution picture, there
needs to be a matching high quality camera. The VS820 uses the
best camera module available; the Sony Super HAD ultra low lux
CCD. This camera offers a 90° angle of view, giving the user a wide
coverage area for maximum visibility.
The Manta camera design matches the high quality Sony Super
HAD CCD camera to a choice between adjustable high intensity blue
LED’s or stealthy infrared lighting. Both lighting options incorporate
MarCum’s exclusive Darkwater lighting technology. The user can
switch between the two lighting options and control the intensity of
the LED’s by making use of the digital keypad. Darkwater technology
greatly reduces particulate reflection and increases viewing distance
by positioning the lights above and behind the actual camera lens.
Adjusting the settings on a monitor has never been so easy. The
digital keypad activates an onscreen display for making adjustments
to the monitor brightness, contrast, color and sharpness. In
addition to adjusting the monitor screen settings, the digital keypad
also controls underwater lighting options, dimmer for controlling
underwater lighting intensity and power ON / OFF.
To clean the monitor screen, use a cleaner recommended for plastic
and a soft cloth towel.
Sharing your video is easy. The video output jack located on the rear
of the monitor allows for adding an external monitor such as a bigger
screen TV or a video recording device.
The camera and power cables have been designed with 90° terminal
connections to prevent cable wear. Along with the 90° connections,
each cable connector is keyed differently to prevent plugging the
cable into the wrong port. The rear cable access panel provides
cable strain relief and is screwed to the back of the monitor. The
panel securely holds the cables in place and prevents unnecessary
wear.
The 75 feet of reinforced camera cable is flexible for ease of handling
yet offers high tensile strength.
