- Internal Dome Design
-
Normally recessed into a false ceiling to provide minimal intrusion in
any indoor location. Or, when surface-mounted the sleek design will let
it blend into a variety of environments for inconspicuously effective
surveillance.
Direct Drive Motor for more accurate and reliable camera movement-
The VN-H657U incorporates a newly-developed Direct Drive
Motor for Pan/Tilt operation. Instead of a conventional belt-type mechanism,
it can provide monitoring with more precision, less operation noise, and
superior durability.
Super Fast (400°/sec) & Super Slow (0.04°/sec) Pan/Tilt Performance-
With a maximum 400°/sec. movement, you won't miss a crucial
scene. Even when pan/tilting manually, the mechanism is very
responsive allowing precise, natural joystick operation. Furthermore,
extremely slow movement of 0.04°/sec. is possible, so you can
carefully examine a scene even at the highest zoom magnification, thanks to
the slow and smooth movement.
Super Accuracy of ±0.03° for Preset Positions-
With an accuracy of 0.03°, the VN-H657U can precisely maintain preset camera
positions even after frequent panning and tilting—especially important at high zoom magnifications. With an ordinary
camera (with low accuracy such as 0.1°), the camera position
gradually shifts each time the camera is panned or tilted, so that
after frequent usage the position becomes totally different from the
initial correct position.
Super Silent Operation of 37dB or lower-
The mechanical noises of a belt-driven PTZ camera are absent. In
fact, the operating noise as measured from a mere 1m away from
our camera amounted to a quiet approx. 37dB. This makes it ideal
for usage in locations where noise should be avoided, such as
hospitals, museums, libraries and offices.
Super Durability and Reliability-
Direct Drive is a very simple mechanism. The number of parts in the
mechanism is far less than that of belt-driven PTZ cameras, so one can
expect the durability to be approximately 160%. And since the
Direct Drive is completely belt-less, there is no possibility of
malfunction due to belts that will break on a regular basis. The
simplified mechanism greatly reduces the chances of malfunction
and increases reliability.
18x Optical Zoom with additional 10x Digital Zoom-
The VN-H657U comes with a powerful optical zoom to provide
image magnification with full optical quality. HD images provide enough detail for an additional 10x digital zoom, for precise identification of subjects at great distances.
Quick and Easy Installation and Maintenance-
Thanks to its "One-touch lock" mechanism, installation is extremely easy.
Simply insert the camera unit to the bracket, and that's all. Maintenance is easy too. You can
replace only the camera unit with the
base unit remaining attached. All preset
settings will resume so that you can
minimize operation downtime.
Ecology-Conscious PoE Plus for Saving Power and Costs-
Built-in PoE Plus (Power over Ethernet) allows the camera to be activated through a LAN cable connection. Both power
supply and video transmission are covered by a single cable, reducing costs for cables, installation, and power.
With a power consumption lower than conventional models, the VN-H657U can minimize impact
on the environment.
HD Resolution for Clearer Images-
The VN-H657U outputs progressive HD images in either 1920 x 1080 or 1280 x 720 resolution for superb clarity. Lower bandwidth images are also available at 640x360, 640x480, 320x240, 720x480 and 352x240.
EasyWide-D Function for backlight compensation-
This function is equivalent to the conventional Wide Dynamic Range
function, allowing pictures to be adjusted to identify details of the
subject by adjusting gamma curve even in difficult backlit conditions.
IR Cut Filter for Round-the-Clock Surveillance-
The IR cut filter automatically switches between ON and OFF
according to the level of ambient light. In daytime it outputs a high-quality
colour image, and at night the filter mechanism removes the
IR filter to output black-and-white images with greater sensitivity.
(When utilizing IR lamps, an external trigger for night mode is recommended.)
Proven Reliability-
Assurance of reliability comes not only from JVC's years of
experience and solid track record, but also by inspecting every single
product at our QC facility based on our strict quality standards.
For all models, this includes grueling tests for Pan/Tilt and Zoom
in/out movement accuracy.
H.264 High Profile / Motion JPEG Full-Frame Dual Stream-
The VN-H657U can stream both H.264 and Motion
JPEG images simultaneously at the full frame rate (30fps for
each stream). H.264 is streamed in either high profile (most bandwidth efficient) or baseline profile (lowest latency) and is ideal for monitoring
full HD images. Motion JPEG images are useful when you need to
record images as evidence data, because of the high quality still
pictures they can provide.
Electronic Sense-Up for Low-Light Situations-
Electronic sense up function provides higher sensitivity level
for monitoring in dark locations by lengthening the exposure
time automatically.
CRT/LCD Selectable Display Mode-
By choosing the display mode that matches the monitor being
used, you'll get images with optimal brightness regardless of
whether you are using a CRT or LCD monitor.
