What steps should I take if I've tried all basic troubleshooting and the 0x1007 error persists?

If basic troubleshooting fails, consider a factory reset of the camera (as a last resort, as it will erase all settings). If that doesn't work, contact Hikvision technical support or a qualified security installer for further assistance. Provide them with details about your network setup, firmware versions, and troubleshooting steps already taken.
