feature, which switches automatically to the high
sensitivity mode (black-and-white).
VN-V26U is equipped with an infrared ray cutoff
filter plug that enables day and night
surveillance. Turning off the infrared ray cutoff
filter when the light intensity level is low, such as
at night, enables you to switch to the high
sensitivity mode (B&W mode).
In the case of VN-V25U, you can switch to a
simple high sensitivity mode by turning off the
color signals when the light intensity level is low,
such as at night (Easy day and night mode).

Cautionary Notes

Maintenance and location of use

䢇 This product is intended for use indoors.

Make sure that you use a housing etc., when
using it outdoors.

䢇 Do not place this product in the following

environments.
Otherwise, it may malfunction or break down.

● Hot or cold locations beyond the

surrounding temperature range of -10°C
to 50°C.

● Locations beyond the allowable operating

humidity range of 20 % to 85 %.
(condensation is not allowed)
Near equipment that emits strong magnetic

●

fields, such as transformers or motors.

● Near equipment that emits radio waves,

such as transceivers and mobile phones.

● Locations with excessive dust or sand.

● Locations that are subject to excessive

vibration.

● Locations prone to moisture such as

window side.

● Locations subject to steam or oil, such as

kitchens.

● Locations that emit radiation, X-rays or

corrosive gases.

䢇 Use of this product or cables connected to

this product at locations where strong electric
waves and magnetic fields are emitted (e.g.,
near radio, TV, transformer, monitor, etc.)
may cause noise interferences in the images
or changes in the color.

䢇 Do not install this product at locations that

may trap heat.
This product also discharges heat from the

surface of the camera unit. As such, do not
install it at locations that may trap heat, such
as near walls.

Handling Precautions

䢇 Do not hang on this product, shake it, or hand

objects over it. Applying an excessive load
may cause the product to fall off and result in
accidents.

䢇 Do not stack up the equipment.

Heat or noise of an equipment may cause
malfunction or failure of the other, and result
in fire.

䢇 Do not block vents around the equipment.

Inadequate heat ventilation may result in
malfunction of this product. Be sure not to
block vents around the product.

Saving Energy

䢇 When this product is not in use for a long

period of time, turn off the power of the
system to ensure safety and reduce power
consumption.

Maintenance

䢇 Be sure to turn off the power before

performing maintenance.

䢇 Wipe this product using a soft cloth.

Wiping with thinner or benzene may melt or
tarnish its surface. For dirt that cannot be
easily removed, wipe using a neutral
detergent diluted with water, followed by
wiping with a dry cloth.

Copyright Protection

䢇 With the exception of the user being the

copyright holder or when permission such as
for duplication has been granted by the
copyright holder, permission is required in
principle for the duplication, modification, or
transmission of copyrighted video and audio
data.
Unauthorized duplication, modification, or
transmission of copyrighted material may
constitute a copyright infringement, and the
user may be liable to compensate for any
damages. When using copyrighted video/
audio data, be sure to check the license
agreement of the copyrighted material
thoroughly.
When rights or rights holders are involved
with regard to the targeted duplicating
subject, permission may be required for
shooting or using (processing) it. Be sure to
check the licensing conditions thoroughly.

Exemption of Liability

䢇 The motion detection feature is not a feature

to prevent theft or fire. JVC shall not be liable
for any damage that occurs.

䢇 JVC shall not be liable for any damage due to

the invasion of privacy by images of this
camera.

Others

䢇 The cable stopper of the alarm terminal may

come off in some cases. When mounting the
cables, make sure to do so carefully.

8

䢇 If a high luminance object (such as a lamp) is

shot, a white smear may appear at the upper
and lower ends of this object on the screen.
This phenomenon (smear) is characteristic of
solid-state image sensors, and is not a
malfunction.

䢇 Some hubs/switches of products that are

equipped with intelligent features may
include a broadcast/multicast suppression
function. Viewing of multicast images on this
product may fail if this function is enabled.

䢇 Electricity can be supplied to this product

either by connecting the AC 24 V power
supply or using the PoE. Make sure to select
only one mode of electrical supply.
Connecting the power cord and the LAN
cable for the PoE at the same time may result
in f ailu re or ma lf unct io n of t he ca me ra.
(A Page 17, 18)

䢇 This product comes with a built-in AGC

circuit. When using this product with AGC set
to AMidB, AHighB or ASuperB, the sensitivity
level increases when the image is dark, and
the screen may appear grainy as a result.
However, this is not a malfunction.

䢇 When using this product with the white

balance set to AATWB, the displayed color
may differ slightly from the actual color
according to the condition of the object due to
the principle of the automatic tracking white
balance circuit. This is not a malfunction.

䢇

The electronic shutter of this product is set to

A

1/30B by default. For regions with a
commercial power supply frequency of 50 Hz,
switch to the flickerless mode during use
under fluorescent lights (excluding inverter
lighting equipment) to prevent flickers.

䢇 When the Black-and-white mode (VN-V26U)

or Easy Day and Night mode (VN-V25U) is
enabled, the image becomes black-and-white
in a dark place. As the sensitivity level is
increased in this case, the screen may
appear grainy and more white spots may
appear. When switching between color and
black-and-white images, the brighter area on
the screen is emphasized, which may reduce
the visibility. However, this is not a
malfunction.

䢇

If the power supply voltage is momentarily cut
off or reduced due to lightning, turning on of
the air conditioner’s power, etc., the image
may be disrupted or noise interference may
occur.

䢇

When using multicast, make use of a
IGMPv2-compliant network switch.

䢇

In the case of VN-V26U, the image and sound
may not synchronize when playing back using
built-in viewer. This is not a malfunction.

䢇

When VN-V26U is sending high bitrate, the
image and sound can be paused during
Black-and-white mode changing. This is not a
malfunction.
