Masking is the final control—not the first
Start by moving, lowering or narrowing the camera so it covers your security purpose. Then use a privacy zone to block unavoidable neighbouring windows, gardens, doors or communal areas.
Reposition first
A physical field-of-view change protects privacy before footage reaches the device, cloud or shared user.
Mask second
Confirm whether masking applies to live view, recordings, thumbnails, alerts, downloads and every user.
Retest often
Firmware updates, replacement cameras, pan/tilt movement and remounting can change the protected area.
Privacy-zone test
- Mark the exact security purpose and necessary field of view.
- Check the view by day, night and with digital zoom disabled.
- Mask neighbouring windows, private gardens and unrelated communal areas.
- Trigger motion inside and outside the mask.
- Review live view, recorded clip, notification thumbnail and downloaded export.
- Test every camera position or preset on pan-and-tilt models.
- Ask another household user to confirm what their account sees.
What masking does not fix
It may not stop audio, reflections, shadows, notification metadata, public-link sharing or a microphone capturing conversations beyond the visible scene. Address each separately.
