Hello,

we are planning to build a semi-detached house (construction has not started yet, only the planning phase) with a developer.

We have already chosen the front door: it is a Rodenberg aluminum door with a plastic core and a triple automatic locking system (changes might still be possible).

The automatic locking system has two bolts (top and bottom) that lock automatically and mechanically and can always be opened from the inside.
The third bolt (in the middle) can only be locked with a key, and once locked, the door cannot be opened from the inside.

We are now considering having a front door with a fingerprint scanner to increase convenience, plus a video doorbell.

I have tried to research the topic and would appreciate your help.

The fingerprint scanner should be from Ekey (as far as I understand, everyone highly recommends Ekey).
We want the fingerprint scanner externally on the video doorbell, not integrated into the door itself.

My first question is: what kind of lock do we need?

Does it have to be a (probably expensive) motorized lock, or would an electric strike for an automatic locking system be sufficient (where the mechanically locked bolts are pushed back electrically)?

Ideally, we would then be able to open the door by fingerprint and also unlock the door via an app linked to the video doorbell (we would select a compatible doorbell and lock), possibly even remotely while away.

I hope you can help me with advice regarding the door lock.

Regarding the motorized lock, the best source of information is the door manufacturer. It is supplied with the door and is usually NOT retrofittable! The motorized lock typically has a potential-free contact that you can control using any connected technology.

My first question is which of the two types of locks you would recommend?

- Automatic lock that mechanically locks (2 bolts) and keeps the main bolt in the middle always open (except, for example, during vacation) and opens the door using an electric strike (the electric strike retracts the two mechanically locked bolts and thus opens the door).

- A real motorized lock that locks and unlocks electrically.

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

Is that correct?

We want to integrate the fingerprint reader 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 hear your opinion first so the door installer doesn’t try to sell me the more expensive option.

Unfortunately, I can’t answer all the questions.

We decided on a “semi-automatic lock” because the door is considered locked from an insurance perspective as soon as it is simply closed, and it only cost an additional 500€ (~$540).

The fully motorized lock from another front door manufacturer was going to cost nearly 1000€ (~$1,080) extra.
So, with the current door, simply closing it means it’s locked.

The door then opens via fingerprint or RFID chip using the motor.

Our (Dahua) video intercom system can also control the motorized lock; for this, we wired it to the indoor unit (monitor). An additional cable from the motorized lock (potential-free relay) connects to our smart home system. This way, I can operate the camera and the lock through a browser (OpenHAB GUI, but our own app is currently in development 😉 ). Any other decent product in this category should offer similar functionality.

Since I am currently upgrading as well, here is a link to another thread where I 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 able to be opened from the inside
- not too loud locking sounds
- can be opened with ekey

We also have the advantage of building new rather than retrofitting.

My question is: is a mechanically locking automatic door sufficient if we then add an A-opener?

Which A-lock would you recommend?

What do you think of the GU Secury Automatic?
