What do you need to start?
- An old smartphone, preferably with a functional rear camera and WiFi connection (Android or iPhone is fine).
- Power supply nearby, to keep the mobile phone plugged in continuously with its original charger.
- Stable Internet access via Wi-Fi. If you're looking for autonomous monitoring during power outages, consider adding a data SIM card as an extra.
- Surveillance camera applicationWe primarily recommend Alfred Camera, but there are many alternatives that are equally effective in essential functions.

Where to place your phone for effective surveillance
Location is key to getting the most out of your “new” home camera:
- Clearly visible area of interest: Target entry doors, windows, garages, or vulnerable areas based on your particular needs.
- As discreet as possible: Try to hide your cell phone so that it doesn't attract attention, avoiding theft and tampering.
- Proximity to an outlet: The mobile phone must always be charged; the battery alone will not last for long hours of surveillance.
- Avoid places with heat, humidity or too much dust that may damage the device.
- Height and angle: An adjustable mount will allow you to focus it correctly and cover the largest field of view possible.
In large homes or if you need extended coverage, you can install several mobiles in different rooms , managing the viewing of all of them from the same app.
