I will add the D1812 fits right into a Door King 1812 backbox for use as a drive-up.? The only problem with it right now is, unlike the D101, they did not allow a “hold open” function on the relays.? I expect that will be cured in an upcoming firmware.? I would recommend putting a separate unit at the man door.

Thanks for the plug! Some of the DoorBird’s have two onboard relays so you could use one for the gate and the man door. Only weird thing is on the gate side is if you want the ability to hold the gate open and have the ability pulse the gate open, you’d need a third relay.

I have had reasonably good luck with Doorbird.? There is an issue with trying to view the camera on a bunch of touch panels as it only supports a few simultaneous streams.? If they have a decent NVR you can add the DoorBird to the NVR and then point the TP video object at the NVR stream output for whatever channel the DoorBird is on.? Their Doorbird apps would just point to the device directly.

If they have SIP intercom and a server like AVLinkPro you can use that to trigger Crestron actions on an incoming call, or the ControlWorks module also works very well.

Have client putting in a powered gate and man door at entrance. What system would you recommend to integrate these into Crestron?? Need camera for both.
