The new WJ-NT314 video encoder carries on its predecessor's crown as a cost-effective way to convert existing analogue cameras into higher performance, user-friendly network recording systems, but delivers even more performance with two channel advanced video motion detection. This allows for both intruder detection and object abandonment and removal to be traced. Intruder detection can pinpoint a suspicious entry whether daylight or after dark and traces the intruder's steps to ensure the source of the intrusion can be easily identified, whether it be over a fence or breaking into a back door. Similarly, the encoder will detect if an object has been left for a configurable amount of time or even if an object has been removed, both will send an alert to the user. Depth correction also allows more accurate detection when the scene includes a deeper depth of field.

This encoder can transmit VGA (640 x 480) images in either MPEG-4 or JPEG at up to 30 frames per second. Alternatively, dual streaming makes it possible to combine seamless remote video monitoring and high resolution recording using MPEG-4 with simultaneous transmission of JPEG images to an optional Network Video Recorder.

The WJ-NT314 incorporates a multicast feature which allows simultaneous transmission of MPEG-4 to multiple clients whilst making efficient use of bandwidth. Utilising network shaping whilst transmitting in MPEG-4, network bandwidth is carefully regulated to avoid sudden bursts in data from the encoder which could result in an overload of the network.

Two-way audio is supported by the encoder to allow live audio monitoring using a locally procured microphone, with the option to send audio back if required.

Control options such as pan, tilt and zoom operations can be selected and controlled remotely on a Panasonic dome camera through a single coaxial cable which is used for both video and telemetry. In addition the multiscreen feature of the WJ-NT314 permits the display of images from up to 16 cameras in four separate Quad screens.

The new network encoder also features a built-in SD memory card slot which makes it possible to back up surveillance images in the event of network difficulties and recorded data can be downloaded by using FTP command.

With a built-in alarm function for external security devices, the WJ-NT314 is suitable for a wide range of applications. It's a straightforward and extremely cost-effective way to convert existing analogue cameras into higher performance, user-friendly network recording systems.
