Full Array of Intelligent Monitoring Functions
in an Easy-to-Use, Compact Design
1/4” Progressive Scan CCD for Clear, Precise Images
The VN-V25U/V26U’s progressive scan images are optimal for
monitoring on LCD or TFT monitors. You can obtain clear images
without distortion even for moving objects.

MPEG-4/Motion JPEG Full-Frame Dual Stream
The VN-V25U/V26U can stream both MPEG-4 and Motion JPEG images simultaneously at the full frame rate (30 fps for each stream).
MPEG-4 distribution is ideal where monitoring with smooth, high frame rate images is required within a limited bandwidth. And Motion JPEG
images are useful when you need to record images as evidence data because of the high quality still pictures it can provide.

Motion JPEG 30fps
Simultaneous streaming at 30fps is not
possible due to poor distributioncapability.
Dropping frames may occur.

Bi-Directional Audio Support (VN-V26U)
The VN-V26U incorporates a built-in mic and an audio output for bi-directional audio communication. So in addition to viewing the
camera spot, you can listen in on the area from a monitoring room. With an external speaker attached, you can speak to or emit an
alarm sound for visitors. A more advanced monitoring system with the capability of conversation and warning can also be configured.

Day/Night Function with IR Cut Filter (VN-V26U)
For more assured day/night security applications, the VN-V26U
features an IR Cut Filter which automatically switches ON or OFF
according to the level of ambient light. In daytime it outputs a highquality color image, and at night the filter mechanism removes the
IR filter to output black-and-white images with greater sensitivity.
With the VN-V25U, there’s the Easy Day/Night Function which
automatically engages color mode when objects are bright, and
B&W mode when it is very dark.
Easy Wide-D Function for Backlight Compensation
The VN-V25U/V26U’s Easy Wide-D function is equivalent to the
conventional Wide Dynamic Range function, allowing pictures to be
adjusted to identify details of the subject even in backlit conditions.

PoE for Saving Installation and Cable Costs
Built-in PoE (Power over Ethernet) allows the camera to be activated
through a LAN cable connection. The PoE function not only
reduces cost for installation and power units, but also enables
uniform management of the power supply and easy response in
case of a power failure in conjunction with UPS devices. (IEEE
802.3af supported)
Easy Setup and Viewing with Built-in Tools
Setup of the VN-V25U/V26U can only be done with Internet
Explorer. Since all necessary tools are built into the camera unit,
just access the camera via a PC and the setup tools and viewer
tool will be available on screen. With the built-in viewer, a variety
of operations including snapshot and alarm reception are possible.
(Recording is not possible with the viewer.)

Privacy Mask for Protecting Intrusive Monitoring
You can protect subjects from invasion of privacy by masking
certain areas of the screen. Mask areas can be specified using
bitmap-format overlay data. Positions and shapes of areas can be
freely set and number of areas are unlimited.
Built-in Viewer
Compact Design
The VN-V25U/V26U is 20% smaller than a conventional JVC boxtype camera. In addition, thanks to the inner tripod base, it can be
installed into an even smaller housing.
Lowest Operating Temperature of -10°C
The VN-V25U/V26U can be used in a wide range of environments.
Its operable temperature range is from -10°C to 50°C (14°F to
122°F). No special housing is necessary for installation even when
switching from an existing CCTV system.
