Frequently Asked Questions
- What does this cable connect to on the intercom?
It connects to the I/O header on compatible Dahua VTO and VTH units to provide access to voltage input, door control, and alarm input/output wiring. - Will this work with any Dahua door station or monitor?
It is stated to suit various Dahua VTO and VTH models, but exact model compatibility is not listed in the supplied information. Check the terminal layout or model documentation before ordering. - What is a common installation mistake to avoid?

- If you are unsure which VTO or VTH models it suits, compare the I/O header style and pin count on your unit with the keyed 12 way connector before purchasing.
