Quick verdict
The E1 Pro is the indoor camera I would point a Home Assistant user at when the requirement is that it streams locally: RTSP and ONVIF are on the camera, it records to microSD, it is on the Reolink integration's tested list, and Reolink's docs say it keeps working with internet access blocked. The pan-tilt head, 5MP sensor, IR night vision and two-way audio cover what a nursery or pet camera needs. Two things to do before trusting it. On current app firmware RTSP and ONVIF are switched off by default and have to be enabled under Server Settings, and one open Home Assistant issue shows a mid-2025 firmware reporting the RTSP state wrongly so the Reolink integration refused the camera while ONVIF still worked. Keep ONVIF or a generic RTSP stream as the fallback. I haven't run this one; the notes come from the spec sheet, the Home Assistant integration docs and what other owners report.
Standout: An indoor pan-tilt camera that streams locally over RTSP and ONVIF and is on Home Assistant's tested list for the Reolink integration, which rules out most of the indoor cameras sold next to it.
