Fixed lenses provide one set field of view, so select them when the camera position and coverage area are already defined. Varifocal lenses allow installers to adjust the field of view, and motorized options can support remote zoom and focus changes when the required framing may change.

Most bullet 4MP IP cameras in this category use Power over Ethernet (PoE), so plan for an Ethernet cable run to an active PoE switch or compatible NVR that can provide network connectivity and camera power. A Wi-Fi model supports 2.4 GHz wireless networking, but installers should verify its specified local power method and confirm adequate network coverage at the mounting location.

Bullet 4MP IP cameras can connect to compatible network video recorders over Ethernet using Power over Ethernet (PoE), while select models support Wi-Fi for connection to a wireless network. Depending on the camera, video can also be recorded to a local microSD card or managed through a compatible app, video management platform, or ONVIF-conformant system.

For bullet 4MP IP cameras, consider IR night vision, a low-light image sensor, and wide dynamic range (WDR) to help maintain usable detail in dark scenes, bright areas, and high-contrast lighting. Some models also offer color-at-night imaging with supplemental white light, while others use infrared illumination, so choose the approach that fits the site’s ambient light and monitoring needs.
