AHD HD-CVI HD-TVI Cámara tipo bala 2MP APTI-H51V21-36W con visión nocturna IR de 20 m, IP66, objetivo de 3,6 mm, salida BNC 4 en 1

Traditional analog CCTV systems often struggle with blurry footage, poor low-light performance, and compatibility issues when mixing different camera brands. The APTI-H51V21-36W bullet camera solves these problems by delivering crisp 1080p video over existing coaxial cabling, with support for AHD, HD-CVI, HD-TVI, and CVBS formats — making it a drop-in upgrade for virtually any analog DVR. Its 20-meter infrared illumination and IP66 weatherproof housing ensure reliable surveillance day and night, indoors or outdoors.

Tips

For best results, mount the camera at a height of 2.5–3 meters and angle it slightly downward to avoid direct sunlight or IR reflection. Use a quality 12V DC power supply and ensure the BNC connector is properly sealed with weatherproof tape if installed outdoors. When connecting to a DVR, set the DVR channel to the matching video format (AHD, HD-CVI, or HD-TVI) for optimal picture quality.
