Frequently Asked Questions
What is the difference between low light, active IR and thermal imaging?
Low light needs natural light and transforms weak natural light image into enhanced electronic image through image intensifier.
Active IR actively emits infrared light and uses infrared beam reflected by the target. It has very poor concealment.
Thermal imaging doesn't need any light and is a passive infrared night vision that detects infrared radiation difference between targets and scene or different parts of an object. It is not affected by changes in surrounding lighting conditions, during night or even in fog, rain and other harsh environments.
Can you block thermal imaging?
In most cases, you cannot. However, infrared rays cannot penetrate walls, and glass can block IR. To avoid detection, you can conceal behind glass or walls to block thermal imaging.
