Powerful Thermal Surveillance

Featuring both thermal and visible channels, this multispectral pan-and-tilt security camera is designed to enable users to enhance their security capabilities, with several AI functionalities, including heat detection, smoke detection, tripwire, intrusion detection, the ability to differentiate between human and vehicle activity, boat detection, and more.

Each model in the series uses a highly sensitive 640×512, 17µm, ≤35 mK NETD thermal sensor to provide exceptional detection capabilities, spotting even the smallest heat signature, by day and at night, at distances reaching up to:

  • 50 mm: 4,525 m (vehicle), 1,471 m (human)
  • 75 mm: 6,787 m (vehicle), 2,206 m (human)
  • 100 m: 9,050 m (vehicle), 2,941 m (human)

Each model offers a selection of 18 different colour palettes, in order to adapt to ever-changing lighting and environmental conditions. These colour palettes include: white hot, black hot, fusion, rainbow, globow, ironbow1, ironbow2, sepia, color1, color2, icefire, rain, red hot, green hot, spring summer, autumn, winter.

Crystal Clear Digital Optics

With a 2688×1520 CMOS sensor and a 4MP camera in the visible channel, this security camera will achieve a clear, high-resolution daytime image, with an optical zoom capable of reaching up to 56x magnification for close scrutiny.

Built-in defogging and an automatic lens wiper that detects rain will ensure images remain clear at all times, regardless of environmental conditions such as dense fog and heavy rainfall.

Laser Range Finding

Certain models in the range include laser range finding capabilities, allowing users to gauge accurate distance measurements at a range of up to 1,500 m when movement is detected within the observation area.

Laser rangefinder equipped models:

  • DHI-TPC-PT8641DB75Z56LR-BMDC48-S23
  • DHI-TPC-PT8641DBM100Z56LR-BMDC48-S23

These can be selected in the dropdown menu at the top of this page.

Taking Thermal & Night Vision Outside of the UK.

Thermal imaging and night vision products are strictly controlled by ITAR regulations and are subject to UK Government Export Licensing Regulations. Dependent on specification, a licence may need to be obtained prior to the export, even temporarily (e.g. holiday), from the UK.

Additionally, some countries may be embargoed, and no thermal imagers or night vision devices can be taken or exported to them. It is the responsibility of the exporter, whether it be a company or individual, to ensure that such a licence is obtained.

Failure to comply is a criminal offence.
