DM-312-S: DM-312 – 18MM, <9HZ Part # 427-0200-40-00S

The 427-0200-40-00S from Flir is a 320 X 256 network outdoor thermal imaging camera with 18mm lens. The FLIR Saros introduces eight new VGA and QVGA resolution options to FLIR’s multi-sensor security lineup. Capable of capturing video in complete darkness, bright sunlight, and through smoke, dust, or light fog, the Saros DM-Series provides superior perimeter protection in the toughest lighting and environmental conditions. A built-in 4K visible light camera operates alongside the thermal sensor to capture minute details in low light conditions. The Saros also integrates with the FLIR United Video Management System (UVMS), as well as other ONVIF-compliant video management systems. This gives users complete control over the all-new dual-sensor viewing mode, alarm functions, and a fully programmable preset tour.



Superior thermal image quality and a built-in 4K visible camera offer versatile, multi-spectral surveillance.

  • Delivers market-leading images in tough conditions, including darkness, glaring light, and through obscurants
  • Onboard 4K visible light camera with e-zoom and low light capability
  • Available 640 X 512 and 320 X 256 thermal resolutions


Choose from a wide range of lenses, along with VGA and QVGA sensors, for optimal detection range in challenging conditions.

  • Choose from eight high-performance lenses, ranging from 95° X 72° to 12° X 9° FOV
  • Athermalized, focus-free lenses


Engineered to reduce exposure to remote security attacks

  • End-to-end encryption for setup, web, and video streams
  • Eliminates the need for port-forwarding
  • Configuration lockdown after initial setup for increased tamper prevention
