I have a camera ip model DS-2CD2763G2-IZS and I want to enable/disable output alarm from mobile app on remote access via internet but i dont see the button for dot it. some alternative?
If you're referring to the output wire from the camera's pigtail to an external siren/alarm, if you exhaust all other options, you could install a Shelly Wi-Fi switch in series to interrupt the cam's output to the external siren/alarm and control the Shelly remotely with their free smartphone app. The Shelly can also operate on a time and day schedule.
EDIT:
Dimensions: 42 x 38 x 17mm / 1.65 in. x 1.5 in. x .7 in.
Operating voltages: The Shelly Plus 1 can operate on AC,110-230V ±10%, 50/60Hz or DC, 24 – 240V / 12V stabilized
