Looking for a motor lock or electric opener for automatic door

Hello,

we are in the process of building a semi-detached house (construction has not started yet, only planning) from the developer.

We have already chosen the front door; it is a Rodenberg aluminum front door with plastic filling and triple automatic locking (changes are probably still possible).

With the automatic locking, 2 bolts (top and bottom) lock automatically mechanically and can be opened from the inside at any time.
The 3rd bolt (in the middle) can only be locked with the key, and then the door can no longer be opened from the inside.

We have now thought about having a front door with a fingerprint scanner to increase comfort + video doorbell.

I have tried to familiarize myself with the topic and would like to ask for your help.

The fingerprint scanner should be from Ekey (as far as I understand, everyone swears by Ekey).
We don’t want the fingerprint scanner in the door but externally in the video doorbell.

I wanted to first ask what kind of lock do we need?

Does it have to be a (probably expensive) motor lock or would an electric opener for an automatic lock be enough for us (the mechanically locked bolts are pushed back electrically)?

Optimally, we would then be able to open the door via fingerprint + open the door via app from the video doorbell (we would take a suitable doorbell for the lock) (maybe even from somewhere else).

I hope you can help me with the topic of door locks.

Regarding the motor lock, the door manufacturer can tell you best. It is delivered with the door and is usually NOT retrofittable! The motor lock then usually has a potential-free contact that you can control through any connected technology.

my question would first be which of the two types of locks you would recommend?

- automatic lock that locks mechanically (2 bolts) and the main bolt in the middle is always left open (except for example during vacation) and the door is opened via A-opener (the A-opener pulls back the two mechanically locked bolts and thereby opens the door)

- real motor lock that locks and unlocks electrically.

I have read that the real motor lock is more prone to malfunctions and much more expensive. Another negative point is whether you can still lock the motor lock at all during a power outage?

Is that correct?

We want to integrate the fingerprint externally into the video doorbell (for example 2N IP Verso) and then place the ekey control unit on the DIN rail.

I would like to know your opinion first so that the door installer does not sell me the more expensive option.

Unfortunately, I cannot answer all questions.

We decided on a "semi-motorized lock" because the door is already considered locked from an insurance perspective when simply pulled shut, and it was "only" a 500€ surcharge.

The fully motorized lock from another front door manufacturer was supposed to cost almost 1000€ extra.
So currently, pulling the door shut = locked.

The opening via fingerprint or chip (RFID) is then done by the motor.

Our (Dahua) video door intercom system can also control the motorized lock; for this, we wired it to the indoor unit (monitor). An additional cable is connected to the motorized lock (potential-free relay) towards our SmartHome. This way, I can control both the camera and the lock via a browser (GUI from OpenHAB, but a custom app is currently being developed ;) ). However, any other reasonable product in this area will also be able to do this.

Since I am currently upgrading as well, here is a link to another post where I have posted something.

Thank you Musketier.

Which locking system did you install in the door that is significantly cheaper than the Mediator??

We have the same requirements

- always locked
- always openable from the inside
- not too loud closing noises
- openable via ekey

We also have the luxury that we are building new and do not have to retrofit

My question is, is a mechanically locking automatic door sufficient where we then use an A-opener with it??

Which A-lock can you recommend?

What do you think of the GU Secury Automatic??
