- Privacy zones can be set in the EZVIZ app to stop recording in parts of the frame.1
- Ownership (not scored): an April 2025 legal opinion published in EZVIZ Network's disclosures says Hikvision holds 48% of EZVIZ Network, and that China Electronics Technology Group is EZVIZ's actual controller. We do not apply Hikvision's own security or regulatory record to EZVIZ.4

Reolink RTSP/ONVIF setup note (added Oct 22, 2026): on many current Reolink models, RTSP and ONVIF (and on some, HTTP) ship switched off. Reolink says to enable them once in the Reolink App or desktop Client under Network > Advanced > Server Settings, or in the web interface where it is reachable78. For cameras attached to a Reolink NVR or Home Hub, enable the ports on the NVR/hub instead7. The App and Client can manage a camera as a "Local Device" using only its UID, username and password, so no Reolink account is needed for this step9. Home Assistant users report the same out-of-the-box behavior on recent firmware10.
