looking for a doorbell camera with POE, ONVIF, app notification and username/password. Replacing an old Silent Witness camera at door plus hopefully to remove Panasonic Door Station, this would cleanup the appearance as well.

Doorbird is a really good option.

?

It has everything you mentioned.

?

SIMPL module is available and works with Home as well.

I've used the Doorbird in the past but was hoping for something a bit less expensive.

You might be able to try something like a Grandstream door station, though I don’t believe it includes an easy app. They have an app called GS Wave but it’s geared more towards VoIP setups. It would require a bit of know-how & might even require a dedicated VoIP / PBX server.

I also checked eBay not too long ago, I saw a few DoorBirds available for auction with no bids. You could try your luck with bidding on one for $300-$400 and hope that no one else drives the price up. But that’s all I can think of.

Best of luck!

Personally, I use a Dahua intercom. I find them to be very good for a reasonable price. They have a better camera image quality than Doorbird.

I also really like the fact that they provide an SDK, so I can completely integrate it into my app and answer directly on it.

I use this model: VTO2201 F-P-S2.

Looks like these are using SIP versus using ONVIF which is what I need to interface with NVR.

Dahua intercom do have ONVIF functionality. I checked one to be sure.

In fact the video part of the intercom acts like other Dahua camera. You can interface them with NVR, this is what I always do.

Avycon now makes an onvif VDB? with strike control outputs and many other options but it's POE not 2 wire.

We've installed one, I haven't played with it much yet.?

Hi,

would you mind sharing some more information or code?

I?ve ordered the model you mentioned for testing, but didn?t find too much info on the control API.

Hi Thorsten,

You can interact with this intercom in two ways. First with Rest API, this API is not public, you have to request it from Dahua and sign an NDA. I have signed the NDA so I can’t send it to you.

You can request it here :

You can find an old one on the web but I don’t think it contains the intercom related part.

I use this API on the processor side to subscribe to the event called when someone rings.

?

The second way is to use the SDK which is public and that you can find here :

?

This SDK provides you the same library used by Dahua to make their App. With that you can access fully to the intercom (it’s the same for NVR) and reproduce all the available functionalities available in Dahua native app.

As I couldn’t do all I needed using Crestron Home or Crestron One with Ch5 project I started to develop my own app. It’s a Crestron Home like app, and I integrated the Dahua SDK on it so I can view the camera from the intercom, listen and talk to the visitor. I also use the same SDK for NVR so I can access to the camera record, display, search and play them directly on it. You can find more details on my website if you’re curious.

?

Send me a email and I can give you a piece of code to handle the ring event if you want.

Hi Thorsten,

I have never tried it with CH. It supports SIP, so there is possibly something we can do with it. When I have a moment, I will try it and possibly create a driver for it. I will let you know if I succeed to do something.
