The DS-2CD2T46G2-4I(2.8mm)(C) is a 4-megapixel outdoor bullet camera manufactured by Hikvision. It features a fixed 2.8mm lens and infrared illumination with a range of up to 80 meters. The camera offers a maximum resolution of 2688 × 1520 pixels at 25 frames per second, with a viewing angle of 103 degrees. Additionally, it supports three independent streams and is rated IP67 for protection against dust and water ingress.

The camera has a maximum power consumption of 12W when the illumination is enabled and can be powered via a 12V DC connector or through an Ethernet cable using 802.3af Power over Ethernet (PoE) standard.
