Overheating Issues in IR Dome Cameras and Our Innovative Solutions

The Severity of Infrared LED Heat Problems

In the security surveillance industry, IR dome cameras are widely favored for their excellent night vision capabilities. However, a persistent technical challenge has been heat dissipation from infrared LEDs. Once activated, the IR LEDs generate significant heat buildup at the front of the camera over extended operation periods (typically 12 hours or more). This not only shortens the lifespan of the LEDs themselves but also jeopardizes the performance of other critical camera components.

For example, a typical IR board with 50 φ5 LEDs can reach temperatures as high as 90°C under prolonged continuous operation. Such extreme heat poses serious risks to device stability.

Root Causes of Overheating

The radiant power of IR LEDs is directly proportional to their operating current. This characteristic has led some non-compliant manufacturers to adopt a "quick-fix" approach—boosting illumination by increasing current. However, this comes at a heavy cost:

1. Higher current directly leads to increased temperatures

2. Excessive heat severely damages the equipment

3. The CCD sensor behind the LED board becomes the primary victim

This trade-off between short-term performance and long-term reliability results in significantly reduced product lifespan and skyrocketing maintenance costs.
