Indoor vs Outdoor Security Cameras
Volume I · May 2026 · 383 words
The physical differences between indoor and outdoor cameras are not cosmetic — they determine whether the camera survives a rainstorm, produces usable footage in direct sunlight, and respects the privacy expectations of people inside the home. The IP rating, housing material, and IR filter design are the three specifications that separate the categories.
IP rating. Outdoor cameras carry an IP65, IP66, or IP67 rating. The first digit (6) indicates complete protection against dust ingress. The second digit (5, 6, or 7) indicates water protection: IP65 protects against water jets from any direction (rain, hose spray); IP66 protects against powerful water jets; IP67 protects against temporary immersion in 1 meter of water for 30 minutes. Indoor cameras typically carry no IP rating because they are not designed for moisture exposure. Using an indoor camera in a covered outdoor location — under a deep eave, inside a porch — may work for months or years but provides no manufacturer warranty coverage for water damage. The Reolink Argus 4 Pro is IP66 rated; the Eufy SoloCam S340 is IP65 rated.
IR filter and sunlight. Outdoor cameras must handle direct sunlight, which can overwhelm the sensor and cause blooming (white-out around bright areas) and IR filter shift. The IR cut filter — a mechanical filter that moves in front of the sensor during daylight to block infrared light and achieve accurate color — must switch reliably thousands of times over the camera's service life. A stuck IR filter is a common failure mode in budget outdoor cameras: the camera is permanently stuck in black-and-white night mode or produces washed-out, pink-tinted daylight footage. Privacy features differentiate indoor cameras: a physical privacy shutter that blocks the lens, a geofencing mode that automatically disables recording when the homeowner's phone is on the premises, and end-to-end encryption are features appropriate for interior spaces where people have a reasonable expectation of privacy. The Google Nest Cam (indoor) includes a physical shutter; the Eufy Indoor Cam includes on-device AI that can distinguish between household members and strangers for selective notification.
