Utilising the latest advanced uncooled LWIR thermal technology, this mid-range LR thermal camera is complemented by a HD video camera.

The LR range of cameras by Silent Sentinel are designed to bridge the gap between cooled and uncooled thermal cameras.

One of the key advantages of the LR range of cameras is to allow customers to benefit from enhanced uncooled performance with overall lower lifetime costs normally associated with cooled thermal imaging.

  • 12μm pixel size
  • Thermal zoom lens up to 75mm
  • <30 mK* (NEdT) f/1.0 @ room temperature
  • Thermal image stabilisation and push autofocus as standard
  • No cooler servicing costs
  • Short to mid-range applications
  • HD IP, PAL, NTSC, and HD-SDI options
  • Human detection up to 3920m
  • Vehicle detection up to 7490m

*As measured after image post-process techniques were applied

The LR Range

The Aeron Ranger LR is an advanced uncooled thermal camera with a zoom lens featuring fast pan and tilt speeds, of up to 160° per second. The LR range has been created to bridge the gap between uncooled and cooled thermal cameras.
