Through Wall Imaging System

It is the stated detection distance for stationary and moving human life signs after the signal has penetrated a barrier more than 65 cm thick. Real range depends on the wall material, its moisture content, the size of the space behind it and what else is in the path. Note also that the manufacturer’s own settings screen shows selectable distance options up to 50 m while the written specification says 35 m; this page uses 35 m, the published figure. Ask which value applies to your barrier type and configuration.

The product page is titled “Through Wall Imaging System” and is filed under the TWR-III listing, while the description and every figure name the unit LSJ HX-RI. Confirm the commercial model designation in writing, so the quotation, the manual and the XF 3010-2020 certificate all refer to the same product and the same configuration.

Low-moisture, non-metallic materials: concrete, soil, rock and wood. Water-saturated concrete, reinforced mesh, metal cladding, foil-faced insulation and steel doors can absorb or reflect the signal and make results unreliable. Ask for a demonstration on your own wall before you commit to a specification.

Yes. The system reports stationary and moving targets and displays breathing and movement signals, so a survivor who is unconscious but breathing can still be seen. Target state is selectable, and a still target should be watched across more than one scan window before it is ranked.

It gives coordinates. Detections are plotted on a 2D plan or a 3D spatial view with per-target coordinates and a movement trajectory, and lateral accuracy is stated at ≤ 10 cm. Depth accuracy is not published — ask the supplier for it in writing, because it decides how precisely a cutting point can be placed.

Yes. Single-target and multi-target modes are both provided, and each detection is listed separately with its own state and position. In a room with several people, read the list together with the 3D view rather than relying on the total count alone.

Startup is stated at 10 seconds. The operator then selects the environment mode (air, through-wall, rubble or wood), sensitivity, target state and a scan window of 45, 60, 90 or 120 seconds, or continuous hold. The radar head is held level and close to the barrier — on a tripod where the ground allows — while the terminal can be read 100–150 m away in an open environment.

Each removable rechargeable lithium battery is specified for 10 hours, and two batteries are supplied, so a full shift is covered with a hot swap in the field. The unit is IP67 rated and specified for −20 °C to +60 °C operation and −40 °C to +70 °C storage. Battery chemistry, voltage and charge time are not published — request them before ordering spares.

No. It answers one question — is someone alive behind this barrier, and roughly where — and it does that without entry. A camera run through an existing gap confirms condition and allows contact, and dogs or acoustic sensors remain useful where the barrier is metal-heavy or water-saturated. Plan the radar as one tool in the search sequence, not as the sequence itself.
