Analog Video Camera Module

With a 1/4-inch CMOS sensor, this small analog camera module offers steady PAL video output for embedded imaging, monitoring, and surveillance applications. The module provides crisp and dependable image signals for standard-definition video systems with an effective resolution of up to 500 × 582 pixels, 420 TV lines of horizontal resolution, and an SNR of ≥50 dB.

The analog camera module, which measures just 38 x 38 mm, is intended for equipment with limited space. When ambient lighting is scarce, its built-in six LED lights help maintain usable image quality by adding extra illumination in low-light conditions. The module runs on DC 12V ±10% and supports a typical 1.0 Vp-p / 75 Ω analog video output.
