Sometimes another background service or an old phone app (Hik-Connect) is trying to log in repeatedly with an old password. This can trigger a constant account lockout, making it seem like your "correct" password isn't working.
Verify your camera model's datasheet. If the hardware lacks PTZ motors or specific smart event detection (like facial recognition), you cannot trigger these features via iVMS-4200. 2. Recording Template Mismatch (PC-NVR) hikvision error code hcnetsdkdll 23 verified
