Laird Thermal Systems Premium TECs Provide Temperature Stability for Outdoor Security Cameras


November 11, 2020

Imaging sensors and other sensitive camera components such as FPGA’s require active cooling to keep operating temperatures below their maximum limit, ensuring high-quality image resolution. Due to solar radiation and increased heat flux density from surrounding electronics, outdoor security cameras can reach temperatures up to 90°C. This may cause performance degradation, loss of image resolution or even system failure. Laird Thermal Systems™ new HiTemp ETX Series can survive in temperatures up to 150°C, making them ideal for spot cooling in outdoor security camera applications.

Designers of outdoor security cameras not only face challenges such as harsh environments and system temperature fluctuations, they are asked to pack a growing number of features into smaller form factors, resulting in higher internal heat loads in the camera. A lack of airflow due to completely sealed compartments makes it even more difficult to dissipate heat away from temperature sensitive electronics such as imaging sensors.

Thermoelectric coolers are solid-state devices that use the Peltier effect to actively pump heat away from electronic devices requiring cooling. Because standard thermoelectric coolers were not designed for high temperature environments, Laird Thermal Systems developed a new generation of thermoelectric coolers to improve reliability and cooling performance. The new HiTemp ETX Series has a robust construction and is assembled with advanced thermoelectric materials that boosts cooling capacity by up to 10%. It also features a higher insulating barrier compared to standard thermoelectric coolers, achieving a temperature differential (ΔT) of up to 83°C.

The HiTemp ETX Series is available in more than 50 models to cover the wide range of emerging applications and support unique footprint requirements, cooling capacity needs, voltage inputs and finishing options.


  • High-temperature operation
  • Reliable solid-state
  • No sound or vibration
  • Environmentally-friendly
  • RoHS-compliant
