Bluecctv BL-IR9843-H-G 650TVL analog camera

This Bluecctv BL-IR9843-H-G is a 650 TV Lines analog CCTV camera designed for surveillance systems requiring standard definition video capture. It uses a 1/3 inch Sony Super HAD II CCD sensor with 976 by 508 effective pixels to produce colour images in daylight conditions. The unit features a fixed 4mm lens and a black weatherproof housing rated for outdoor installation. Power is supplied via a 12V DC connection.

Suits installers needing fixed-lens IR coverage

The 42 infrared LEDs provide illumination for 0 lux environments, delivering a quoted IR distance of 60 feet for night-time monitoring. Buyers who require varifocal lens adjustment, motorised pan-tilt-zoom functionality, or higher resolution formats such as HD-SDI or IP streaming should consider alternative camera types. The fixed 4mm focal length also limits field-of-view flexibility for wide-area or long-range identification tasks.

4mm fixed lens sets the field of view

The 4mm fixed lens determines the camera’s viewing angle and magnification, which cannot be changed after installation. This single optical specification decides whether the coverage matches the scene width and target distance required for the application. Verify that the fixed focal length aligns with the intended monitoring area before purchase.
