The Defender Fusion continuous zoom thermal imager is the
system of choice for security and surveillance
requirements. With outstanding long-range target detection
and recognition, the Defender combines exceptional
performance with tested reliability and ease of use.
The defender Fusion 500CT is ideal for border and
coastal patrol, military/Law Enforcement
security & surveillance and long range remote
sensing for critical facilities, ports, borders, &
government installations. The defender is a passive
Thermal infrared system which requires no light to
products an extraordinary day like image. The Defender
offers supreme human & vehicle detection and recognition.
The defender can be used as a LORIS replacement turn key
system.

The Defender offers an extraordinarily clear
long-range thermal image with the convenience of a
continuous zoom. Its horizontal field of view extends
smoothly from 1.10° to 5.5° with three preset positions,
and it enables man sized target detection at ranges in
excess of 7km in good conditions. The Defender utilizes
advanced InSb
(Indium Antimonide) photo detection technology in a
320 x 256, 30µm pitch focal plane array and operates in
the 3-5µm spectral region-the best choice for marine and
high humidity environments. Self-protected in a
proprietary environmentally sealed, nitrogen backfilled
enclosure for simple secure installation, it is stable
over variable temperatures and conditions. The Defender
employs remotely controlled and user-friendly plug and
play operation.
The defender system can be used as a fixed system or
integrated into our military pan tilt rack systems.
