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.
