Recommendations

For reliable remote access and recording, place the monitor within strong Wi‑Fi coverage or use a wired network connection where possible. Use a high-quality Class 10 MicroSD card formatted as specified by the manufacturer, and regularly check firmware updates and network settings to maintain compatibility and security.
