Can an iPhone be used as a security camera?
Short answer
Yes, you can repurpose an iPhone as a home security camera using third-party camera apps or smart home software. An iPhone provides high-definition video, motion sensors, and wireless connectivity. However, using an iPhone as a continuous security camera requires careful attention to software updates, device power, battery swelling risks, and account security to prevent unauthorized access to your video feed.
The details
Repurposing an old phone gives hardware a second life, but software support is a critical factor. CISA recommends updating software regularly and replacing devices that no longer receive security patches. If your spare iPhone is too old to receive active iOS security patches from Apple, connecting it permanently to your home network creates security vulnerabilities. Cyber actors target unpatched devices to gain entry into private networks.
Account configuration also matters when you transmit live feeds. Any streaming application or cloud service you configure on the device must be protected with strong authentication. CISA highlights that multifactor authentication prevents unauthorized access even if login credentials are stolen. Secure your camera app account with a strong, distinct password and turn on multi-factor authentication to keep your video streams private.

What to do
- Wipe the iPhone and remove personal accounts, messages, and sensitive photos.
- Update iOS to the latest supported version to patch known vulnerabilities.
- Install a reputable security camera application from the official App Store.
- Enable multi-factor authentication and a strong, unique password on the camera account.
- Mount the phone near power using a certified charger to prevent battery overheating.
