High Capacity Long-Lasting Batteries

Rescue teams are often positioned in out-of-the-way locations and in time-critical situations. Being able to quickly swap out a battery and know it will last for the duration of a much-needed rescue mission is vital. 

ZistosHD Rescue Systems all use long-lasting, rechargeable Smart Lithium-ion batteries. The Extended Capacity Battery (BAT-15XL) is included with all of the ZistosHD Rescue Systems. The BAT-15XL can typically run for 6-12 hours, depending on camera options and illumination settings. The battery also has an easily viewable, built-in five segment LCD charge level indicator, which displays the charge level even when it is not connected to the system.

Articulating Motorized Poles

Lightweight, easy-to-use rescue tools are essential for technical search teams. The ZistosHD telescoping poles offer the flexibility and durability needed for real-life conditions.  The HD motorized series are weatherproof, lightweight carbon fiber poles, which makes using them excellent for extended time, and in any environment. 

The ZistosHD motorized poles allow the operator to adjust the camera position remotely. This is important when the pole is extended and the camera is not accessible to the operator, or it is inserted into a collapsed structure or void space in rubble.

These poles terminate with an articulating camera mount and enable the operator to remotely rotate the camera to pan +/- 120°. The motion is controlled using the buttons on the HD Handle, or using the touch screen controls on the display. The operator can control zoom, video capture, illumination and more. The HD Poles use easy twist collars to expand and collapse, and are available in lengths from 3 to 30 feet. Unlike many existing articulating pole cameras, our camera has a specially designed slip-clutch that provides protection against damage to the motor assembly if the camera is forced backwards when in use.

Low-Latency Wireless Video Streaming

For rescue missions, low-latency video supports operations that require near real-time access to quickly changing conditions. Many other digital video systems are plagued by slow response that can create a delay of many seconds between the event and the viewable video image. The low-latency performance of the ZistosHD systems allows the video images to be viewable without a significant delay.

The system can also be utilized in a wired configuration when wireless operation is not feasible. The ZistosHD system will directly support up to three different wireless viewers concurrently. The encryption of the video stream helps ensure that sensitive information will not be intercepted by unauthorized parties. The system supports WPA2-PSK (AES) encryption for secure video transmission. It also can be configured for fully-wired operation for situations where wireless operation is not practical. The system’s video is also compatible with commonly used ATAK compliant external radios.

Wide Variety of Interchangeable System Options

ZistosHD’s modular design allows maximum flexibility for the rescue team in the field. One system can be configured to serve multiple applications, and added to as needs arise. Interchangeable poles — different types and lengths — can be paired with an array of camera technologies such as ultra low-light, 10X zoom, and dual mode thermal that generates both standard B/W video and thermal imaging. Maximizing the usefulness of a system also enables rescue departments to get the most from their investment in Zistos equipment. ZistosHD components are deliberately designed to be compatible with new and future system options.

External Network

Video images can be shared with others to view situations as they unfold in real-time, on multiple displays. Zistos offers an optional WiFi network bridge attachment, which enables multiple ZistosHD systems to be simultaneously viewed on a single computer via a common external network at a command location.

Thermal Imagers: ZistosHD Dual Mode Thermal Camera vs Thermal Fusion Technology

Thermal cameras have come a long way since 1929 when the first infrared-sensitive camera was invented.  This new technology was initially considered exotic and it was expensive. In the last few years, the cost of thermal imaging technology has come down significantly, although thermal imagers with reasonable image resolution can still be pricey. Thermal fusion cameras, that utilize very low-resolution thermal sensors (80×60), which are enhanced by blending in a standard video signal, can be very inexpensive when compared to medium to high resolution thermal imagers. In certain applications the performance and suitability of images that utilizing thermal fusion can be questionable.

Thermal fusion is achieved when an image from a standard video camera is layered on top of an image from a low-resolution thermal sensor. This produces an image that depicts a black & white or colorized visualization of an object in the field of view of the thermal sensor that is outlined with an edge created from the standard video camera. The two cameras work in conjunction to give you a crude thermal image with enhanced edges. When used in this manner, the low resolution thermal fusion can produce a reasonable and usable thermal image. There are many applications where this approach is effective. It is useful in applications such as inspecting breaker panels, steam pipes, machinery, engines and other inspection applications where there is sufficient light for the standard video camera to produce a good image that can be utilized in the blending process. It also helps to know what you are looking at in advance, this is not always the case in many thermal imaging applications.

Image shows Thermal Fusion under perfect conditions

The shortcomings of this approach occur when the standard video camera that is producing the edge enhancement overlay on the thermal image doesn’t have enough light to create its outline. The image produced by the thermal fusion camera is now significantly compromised and may be of minimal value. Without the outlined overlay from the standard video camera, the thermal image has such low resolution that the image ends up looking like blotches of ill-defined color.  The image may not convey enough detail to make an accurate assessment of individuals and environment. When thermal fusion is utilized in tactical or victim location applications, you may not always have enough illumination for the standard video camera to produce a reasonable image. Additional external IR or white light illuminators will help, but they still might not deliver adequate illumination in all cases. This means that you may not be able to differentiate a partial or even full image of a human, from the background environment.

Image shows Thermal Fusion without enough light to produce outlines

The ZistosHD Dual Mode Thermal Camera (THC-51D-HD) allows the operator to instantly toggle between a 320×256 resolution thermal video camera and a 640×480 resolution, low-light, standard B&W video camera. The B&W video camera also has built in IR illumination that can further assist in low light conditions. Instead of overlaying an outline on top of a low-resolution thermal image, we use a higher resolution thermal camera in the same housing and an even higher resolution B&W low-light camera to switch between the two different images. We believe this construction is superior to thermal fusion for the following reasons.

Images show THC-51D-HD in both Thermal Mode & B&W IR Mode
  • The higher resolution thermal image produces a usable image without the need of any enhancement.
  • The secondary low-light B&W standard video camera can produce a video image that can convey additional visual details of the subject and environment.
  • In the THC-51D-HD, the Thermal and B&W IR Cameras are in the same housing. Therefore, there is no need to switch camera heads. It’s all done with system controls.
  • If the standard video camera in the thermal fusion process does not have enough light to produce a usable image the result is an extremely low-resolution thermal image which can be of limited value.
Left, Thermal Fusion Camera without enough light to produce outlines. Right, ZistosHD Dual Mode Thermal Camera in Thermal Mode in the same conditions.
  • The THC-51D-HD camera’s thermal mode can provide thermal detail regardless of ambient light levels.

All in all, despite thermal fusion being available as a new and low-cost thermal technology it may not be suitable as an imaging tool for many tactical and victim location/rescue missions, or any application where you can’t count on adequate illumination for the standard video camera to function. A higher resolution, standalone thermal image, such as the images produced by the ZistosHD THC-51D-HD camera, will in many instances be of more value than an image produced using a thermal fusion camera.
