Key Features

Disguised as a standard smoke detector, this covert unit delivers dual-output flexibility for both HD-TVI and legacy Analog systems. It maintains an exceptionally clean signal with an S/N ratio exceeding 50dB, utilizing Sens-up and Digital WDR to capture detail in dim interior lighting. Advanced 3DNR (Digital Noise Reduction) and ATW (Auto White Balance) ensure a natural image, while the UTC function allows for effortless remote OSD adjustments.

Technical Context

The internal sync system relies on a 5.42mm × 3.41mm sensing area to process high-resolution video without the need for external illuminators. It operates with a versatile electronic shutter ranging from 1/25 to 1/50,000s, allowing the camera to adapt quickly to flickering indoor lights or rapid movement without sacrificing image stability.

Installation Notes

Tailored for climate-controlled environments, this DC 12V-powered camera operates reliably between -10°C and 50°C. Its covert form factor is strictly for indoor applications where discreet placement is mandatory. The low-profile design and 10%–90% humidity tolerance make it an ideal choice for offices, retail spaces, or hallways requiring hidden, high-definition oversight.
