Hikvision 2MP AcuSense Fixed Bullet Network Camera (DS-2CD2023G2-IU)

Hikvision 2MP AcuSense Fixed Bullet Network Camera
AcuSense DS-2CD2023G2-IU 2MP Network Bullet Camera from Hikvision. This unit uses a 1/2.8" progressive scan CMOS sensor to capture 1920 x 1080 resolution video at 30 fps. IR LEDs provide up to 131' of night vision. The camera's 2.8mm fixed lens delivers a 107° horizontal field of view. A built-in microphone enables the camera to pick up audio. A memory card slot accepts microSD/SDHC/SDXC cards up to 256GB (available separately). Integrated PoE technology simplifies connectivity by enabling the transfer of power and data through a single cable.
