| Platform | L21 | ||
| Solution | NT98562+SC2337P 2MP back-illuminated CMOS 1/3” target | ||
| intelligent | describe | ||
| Humanoid detection | support | ||
| Audible and visual alarms | Supported; after human detection triggers an alarm, it can be linked to alarm light panels and voice alarms. Supports free switching between three modes: Infrared mode: At night, it provides a black and white image with infrared illumination. When a human figure is detected and an alarm is triggered, it can be linked to a voice alarm. White light mode: The image is full-color white light at night. When a human figure is detected and an alarm is triggered, a voice alarm can be activated. Intelligent dual-light: At night, it provides infrared supplementary black and white images. After human detection triggers an alarm, it can be linked with a white light panel and voice alarm, and the image switches to full color. |
