Choose electronic cameras by mounting location, viewing area, and lighting conditions: mini domes suit discreet indoor installations, while bullet and dome cameras with IP67 protection support many outdoor or mixed environments. For changing scene sizes, consider a motorized varifocal lens, and for low-light areas, look for infrared night vision or color-at-night imaging, along with Power over Ethernet (PoE) and local micro SD storage for installation flexibility.

When selecting electronic cameras, compare fixed lenses for consistent viewing angles or motorized varifocal lenses for adjustable framing, along with four-megapixel or eight-megapixel resolution based on the detail your scene requires. For low-light coverage, look for infrared night vision, wide dynamic range, and image sensors designed for low-light performance, while color-at-night cameras add supplemental white light to help retain color in dark scenes.

Electronic cameras connect to compatible network video recorders over an IP network, often using Power over Ethernet (PoE), while local microSD storage can support standalone recording. Mobile apps provide access to live video, recordings, and camera management, and supported smart home platforms can display live streams through network or cloud-connected integrations.

Plan for Power over Ethernet (PoE) through an Ethernet cable connected to a compatible active PoE port, or use the camera’s specified power method when applicable. For storage, many cameras support local microSD cards up to 512 GB, while network requirements may include an Ethernet connection to a compatible network video recorder (NVR), the camera app, or an ONVIF-conformant system.
