Choose a 2.8 mm camera’s resolution based on the detail you need, the viewing distance, and the scene size, since higher resolutions can provide more detail for identification and digital zoom. Lower-resolution options can suit general monitoring while using less storage and bandwidth, while four-megapixel and eight-megapixel cameras may better support areas where finer image detail matters.

Yes, 2.8 mm cameras can support indoor, outdoor, and low-light surveillance, with many models offering weather-resistant housings, infrared night vision, or color-at-night performance. Choose a model with the appropriate housing rating and low-light features for the installation environment, since capabilities vary by camera.

A 2.8 mm lens generally provides a wide field of view, so consider the area’s size, camera mounting height, viewing angle, and the level of detail needed at the edges of the scene. Position the camera to limit obstructions and glare, and select features such as wide dynamic range, low-light performance, night illumination, or onboard analytics based on the lighting and monitoring needs of the location.

Connect the 2.8 mm IP camera to an active PoE port on a compatible PoE switch or video recorder using an Ethernet cable, which carries network data and power to the camera. Then use the recorder or camera management app to discover the camera, assign or confirm its network settings, and add it to the recording system, checking that the device supports the camera’s resolution and video protocol.
