Do Security Cameras Work Without the Internet? What You Can and Cannot Do

Wired cameras connected to a local NVR record fine without internet, since footage is stored on the NVR's own hard drive. What you lose without the internet is remote viewing on your phone and push notifications. Cloud-only cameras stop working almost entirely without an internet connection, since they have nowhere local to record to.

What still works without the internet?

A wired IP camera system with a local NVR or DVR continues recording 24/7 regardless of internet status, since the camera-to-recorder connection runs over your own local network cable or Wi-Fi, not the internet itself. You can still view footage directly on a monitor connected to the NVR.

What stops working without the internet?

Remote viewing through a phone app, push notifications, and any cloud-only camera that has no local storage option at all. If a camera's entire business model depends on a cloud subscription with no local SD card or NVR fallback, it effectively stops functioning as a security device the moment the connection drops.

Local NVR system vs cloud-only camera during an outage

Real product check

For guaranteed local recording regardless of internet status, a wired PoE kit with an NVR such as the Hikvision 6MP Custom CCTV Kit stores everything locally with no dependency on your connection. If you specifically need a camera with a genuine offline fallback in a wireless form factor, confirm SD card or local storage support before buying rather than assuming any Wi-Fi camera has it.

FAQ

Does a power outage affect this the same way as an internet outage? 

No, that is a separate issue, see "What Happens to CCTV During a Power Outage?" below for what happens when the electricity itself drops out.
