Xandem Tomographic Motion Detection (TMD) (Beta)
Xandem's tomographic motion detection (TMD) (Beta) technology is the next generation of motion sensing. A Xandem TMD system can be completely hidden from sight, can see through walls and obstructions, and is virtually impossible to defeat. The system integrates easily with existing panel equipment using normally-closed and normally-open contacts.
A Xandem TMD comes with:
- Sensing nodes: These are the devices that are placed around the area of interest. The exact number of nodes depends on the size of the area and the application. They can be powered by USB plug-in or with a 3 volt low-power wiring. Talk to a Xandem sales representative for information on how many nodes should be used.
- Processing unit: A device that runs the sensing algorithms. When motion is detected, normally-closed and normally-open contacts are opened/closed. This allows the sensing system to be directly integrated into standard panel equipment. The PU is powered the same way as the nodes.
- Documentation: Instructions on how to configure and use the system.
Simple Installation
Xandem devices can be quickly placed in convenient locations without worrying about obstructions or areas that are problematic for infrared and cameras systems. The nodes are simply plugged in or wired around the area of interest, and motion is detected inside the perimeter of the network. The devices can even be embedded within walls for heightened security and aesthetics.
The hardware devices presented in these videos are prototypes. Xandem TMD hardware is much smaller and comes with protective casings.
Powerful Detection Capabilities
- Through-walls/obstructions: Xandem technology can sense motion and presence through walls, furniture, and other obstructions. That means the system can detect movement in rooms where no device is deployed..
- Hidden: Xandem nodes can be hidden behind walls, inside boxes, or in any other non-metallic container. This allows the sensing system to remain completely hidden from visitors, increasing security and aesthetics.
- Unbeatable: Cameras, infrared, thermal, and other optical devices can be deceived by covering the sensor or insulating an intruder. Xandem's technology uses radio waves that interact with the mass of a body, making it virtually impossible to beat.
- Flexible: Xandem's technology can be installed in many different shapes and configurations.
- Crowd detection: Xandem technology can detect various levels of motion, like if a crowd or party is within the secured area.
- Privacy: Xandem technology is not invasive of privacy - no optical imagery is used.
False Alarm Immunity
Xandem motion sensing technology more robust to false alarms than competing technologies like infrared, cameras, ultrasound, and traditional microwave. The following events will not cause a false alarm:
- Blowing balloons and decorations
- Abrupt changes to heat and light
- Small animals and pets
- Dust and debris falling on devices
- Insects crawling across devices
