How it works
An IP camera is a networked computer with video, accounts and software. Its security depends on the camera, the recorder, remote-access service and network configuration together. Protecting only the mobile viewing app leaves other access routes and device software outside the review.
A practical example
A camera may record locally while remote viewing uses a provider account. A shared administrator password or an unnecessary internet-facing port can expose access independently of where footage is stored. Local recording is therefore not the same as restricted remote access.
What to check
Identify the exact model, supported firmware and all authorised users. Replace shared or factory credentials, review remote access and apply supported updates. Separate cameras from unnecessary network access where the design allows it. Confirm that recording and legitimate viewing still work after each change.
Review who still has access after a change of resident, installer or administrator. Removing a local user may not revoke a separately shared cloud account or mobile-app session.
Limits and safe use
Do not open ports simply because an old guide recommends them, or disable authentication to make a stream appear. Security settings do not establish that a camera position or retention policy complies with privacy rules. Protect footage and account recovery separately, and plan replacement when the manufacturer no longer supplies security support.
