Many people assume security cameras need Wi-Fi. In practice it depends on the type of camera, and the answer is often "a network, but not necessarily the internet."
Wired (PoE) cameras
Power over Ethernet cameras connect to a recorder or switch by network cable that carries both power and video. They do not need Wi-Fi at all, and they keep recording to the local recorder even if your internet goes down. This is the approach we recommend for most professional installations because it is the most reliable.
Wi-Fi cameras
Wi-Fi cameras send video over your wireless network. They are easy to place, but they still need power, either from a plug or a battery. They can be affected by weak signal, interference and busy networks, and battery cameras need regular charging.
What needs internet and what does not
- Recording to a local recorder: no internet required
- Viewing on a screen at the property: no internet required
- Viewing from your phone away from home: needs an internet connection
- Cloud storage and some smart features: need internet and are often a paid service
Practical advice
- For main entrances, driveways and business sites, use wired PoE cameras
- Use Wi-Fi cameras for hard-to-wire spots where a small compromise is acceptable
- Give the camera network a reliable router and strong, unique passwords
- Keep camera firmware updated
Standard Ethernet runs are limited to about 100 metres (328 feet), which we explain in our guide to PoE security cameras. See our security camera installation page for more.
