The PZT (Planar Zone Transceiver) is a new generation GPS/RFID solution for the military and commercial industries. Its primary function is to synchronize two channels, the PZT emitter and the GPS receiver, to form a single channel, the PZT output. The output from this GPS system is an analog signal that can be decoded by the GPS receiver using a demodulation technique and the correct time. This single channel solution opens up the opportunity for flexible solutions and enables quick detection of moving vehicles and other targets, such as humans, animals, or even equipment. It also enables the easy tracking of personnel, as all data is recorded and logged in the devices of the user.
The PZT works as an autonomous unit for military and tactical applications. The GPS device can be mounted on a vehicle, ship, or aircraft, and the data gathered by the PZT can be sent to the user, who will then decide what actions to take. It has been tested on both the ground and in flight conditions, and has passed safety benchmarks. The PZT can measure a distance of up to 2. 1928 meters with an accuracy of about 0.90 percent, using both the regular GPS and the 30x optical zoom lens. It has a low power consumption, and runs silently.
The PZT uses the High-Bandwidth Digital optical zoom lens, which has a wider angular field of view than the optical zoom lens. It makes the PZT the only GPS receiver that can support the HD format. This means that the PZT can display digital imagery in full HD, allowing for more detailed maps and more efficient situational awareness. The 30x optical zoom lens also offers a higher resolution image than the optical zoom, resulting in more detailed imagery with less distortion. Other key features include a self-contained power supply, battery charging cable, user-accessible controls, and a hands-free monitor.
Two specific areas of the military where the ptz optics are used extensively include the United States Marine Corps and the United States Air Force. The Marine Corps uses the PZT for situational awareness, tracking enemy troop movements, and building targeting databases. The US Air Force has been using the PZT for live streaming video since 1995, and continues to use the camera as part of its overall tactical gear. The tactical applications of the PZT camera and its ability to capture digital imagery have made it a favorite among deploying soldiers. In addition, the camera is useful for providing video game-style play for large numbers of people in an area.
Currently, there are two different modes of operation for the PZT camera. The first mode operates using an analog signal; the video and audio feeds are transmitted through a radio signal. This mode allows the operator to change the display depending on the type of environment (day or night, daytime or nighttime, etc.) In this way, the operator can adjust the visual display for changing operating conditions. It also provides the capability to pause, rewind, fast-forward, and switch to another video mode.
The second mode for the PZT is called optical zoom. With the optical zoom, the operator can pan the camera by moving the joystick in a circular motion around the perimeter of the lens. When the circular motion is no longer necessary, the operator simply adjusts the focus and zooms in on the subject. The optical zoom provides greater detail and greater dimensionally accuracy than the analog mode, which limits the range and resolution that can be processed.
The benefits of the PZT optics system over other systems are many. First, the camera can stream HD-DVD movies directly to a computer (or to a DVD recorder) using a Firewire interface. Next, the PZT system allows the user to preview live video streams as they occur. The user can "rewind" to previous frames, "pause" at specified times, and play back recorded media as and when desired. In addition, the system integrates seamlessly with the ip streaming device and, through the use of the proprietary Realtek IP network, allows the PZT to connect to an existing network or to any internet-connected computer and to access the internet anywhere in the world.
As additional capabilities are implemented and as new devices - such as the HDMI output and the full hd compatibility with HDTV's - are added, even more spectacular results can be achieved. At a recent live event, for instance, a PZT camera was able to capture and deliver the image of a sailboat racing against the fierce wind and white noise in calm waters, to the amazement of all attendees. This incredible demonstration of real-time imaging ability represented a tremendous advance in how such a system can work, and it represented a significant step forward in expanding the scope of high definition imaging. If a company, for example, needed to obtain a video stream of an airplane flying over London, it would be relatively simple to obtain that same video stream via a PZT camera mounted on an aircraft. Today, that same camera, when coupled with a powerful computer, has the potential to transform how surveillance activities are managed.
