Question 1

What is the difference between a 2-wire and an IP video intercom?

Accepted Answer

A 2-wire kit runs power and signal to both the door station and the monitor down the same pair, so it usually reuses the cable an old handset already had — the standard retrofit, and the reason it suits buildings with no data cabling. IP runs over Cat5e/Cat6 with PoE and sits on the site’s structured network, which suits new installs and anywhere a data run already reaches the door.

Question 2

Can I add more than one indoor monitor?

Accepted Answer

Usually yes, within the limit the specific kit states — check that figure before you promise a client a second screen upstairs, because it varies by model. Adding a monitor later is normally a matter of the extra unit and its power rather than a new door station.

Question 3

Will a video door entry system work with my CCTV recorder?

Accepted Answer

Check the spec sheet for the exact station and recorder before you quote it — this is a model-by-model question, not a range-wide one. The structural difference is topology: an IP door station sits on the same Cat5e/Cat6 network as an IP camera system, while a 2-wire kit is a closed pair between the station and the monitor and shares nothing with a recorder.

Question 4

Do I need a separate lock, or does the kit release the door?

Accepted Answer

The door station provides the release; the lock itself is separate unless the kit’s own spec says otherwise. Pair it with a magnetic lock, an exit button and a suitable 12V supply — those parts are in our access control range.

Question 5

What does a flush frame need behind it?

Accepted Answer

A chased-in back box sized for the number of modules. If you cannot chase the wall, use the surface-mount box instead — same modules, no building work — and add a rain shield if the panel is exposed.
