Can I use an old phone as a home security camera?

Yes. With Call Pet, an old phone can act as the camera and your main iPhone can act as the viewer. It is useful for temporary indoor monitoring, especially for renters or travelers who do not want to install hardware cameras.

  • Video stays off cloud storage
  • Works best indoors with stable power and internet

Best for

  • Renters
  • Travelers checking on home
  • People testing whether they really need a dedicated camera

  • Outdoor weatherproof security
  • Insurance-grade or business-grade surveillance requirements

Follow-up questions

Where should I place the old phone? +

Place it indoors, plugged into power, with a clear view of the area you care about: entryway, living room, pet area, or hallway.

Is it a replacement for a professional security system? +

No. It is a private live-view camera option, not a monitored alarm service or professional security system.
