Operating Precautions
● VN-C11 designed for indoor use. For outdoor use, prepare a proper housing to cover and protect
the camera.
● The product should not be installed or used in the following locations.
• Locations subject to rain or water.
• Locations with hot air or oil vapors such as in kitchens, etc.
• Locations where the allowed ambient temperature (0 °C to 40 °C) is exceeded.
• Locations exposed to X-ray radiation or where strong electrical or magnetic waves are gener-
ated.
• Locations where corrosive gas is generated.
• Locations with vibrations.
• Locations with excessive dust.
● If VN-C11 and the cables connected to VN-C11 are installed at a location where strong electrical
or magnetic waves are generated, near a radio, TV set, transformer, motor etc., the quality of
image and color may be affected.
● If a high-intensity object (such as a lamp) is shot, the image on the screen may have vertical lines
(smear) or blur (blooming) at its periphery. This is a characteristic of the CCD, and is not a defect.
● Clean the unit with the power turned off. Use a soft cloth like cotton flannel to wipe out dirt. Do not
use paint thinner or benzine as a cleaning agent as this may cause melting or tarnishing of the
unit surface. If dirt is persistent, use a cloth soaked with water-diluted mild detergent and then
wipe it with a dry cloth.
● Because the cable holders of the terminals could come loose, perform cable connection carefully
and securely.
● Insufficient dissipation of heat from the unit may cause damage. Use the unit at a well-ventilated
location. In particular, do not block the unit’s cooling-fan ventilation opening.
● In a narrowband environment, for example, of dial-up connection, smooth running of MPEG4
images cannot be obtained. This is due to the product design, therefore not a defect.
● When this product is installed in an NAT environment, MPEG4 images cannot be viewed. This is
due to the product design, therefore not a defect. (This product uses a network protocol called
RTP for transmitting MPEG4 images. Generally, an NAT router cannot carry out NAT translation
of RTP packets properly.)
● Certain hubs and switches equipped with SNMP functions have a broadcast or multicast control
function. If the function is enabled, multicast images created by this product may not be viewed
properly.
● To save electricity, turn off the power to the system when not in use.
● As local recording images are saved to the volatile memory of the product, the images are
deleted if the power is turned off.
