The short answer
Prepare the camera address, local account and protocol before opening a camera wall. A single stable view is the baseline for every later change.
Work through the checks
Identify the camera by model, hardware revision, firmware and MAC address. Keep this inventory separate from passwords; two devices with similar names may expose different protocols.
Read the camera address in your router’s DHCP client list or the manufacturer’s local setup tool. Confirm the entry against the MAC address instead of guessing an address.
Use the camera’s local protocol account. A cloud app email address is not necessarily a valid RTSP or ONVIF login. Grant only the viewing or control permissions actually needed.
Check the model manual for an ONVIF service switch and any separate ONVIF account. Use the configured service port; do not assume it equals the RTSP port.
What to verify
Test one camera and one stream before opening a larger camera wall. Keep the camera settings unchanged while you establish whether the first live image is stable.
Sources and scope
AeoCam is available for Windows. Camera settings below describe protocol preparation, not a certification of a particular camera or a promise of every feature in every app version. Check the installed build and the Microsoft Store listing for current availability.
Vendor documents describe the camera or protocol. No physical-camera compatibility test is claimed here. Menus and capabilities can change with model and firmware.
