Alerting Systems

For a long time , I've been researching alerting systems to install in my flat.

I might have the CI , but essentially , I'm deaf . I do hear enviromental noises , and speech ( and my speech discrimination is going up slowly but surely.
Also don't forget..when I'm sleeping , or in the shower , or even just taking a break from hearing..what happens ?

At first I thought I'd get the cheaper option - a Geemarc alerter device with a remote doorbell.It was only 100€ in Greece.
I was told that the remote doorbell might be stolen , and anyway , I couldn't drill anything outside my door.There was still also the downstairs door buzzer to consider.So that was discarded.

Back to square one.

It was only this or the Bellman Visit 868 system in Greece.
The latter works a different way.The Door transmitter is hooked up beside the actual doorbell , programmed and it 'remembers' the sound of the doorbell to transmit an alert to the Bellman 868 receivers ( it also can be expanded with a baby monitor, fire alarm , telephone monitor , etc ) and has a host of receivers to get what suits you better.A friend loaned me the grey small pager to try out , and I got the Door Transmitter , hooked it up and I tried out the whole system.It works beautifully, dispelling all my doubts that I had initially , since it was completely wireless.It works like a charm ( had it for two weeks now , works better than I even thought! )

A thing that Bellman should make is a plug option for the travelling people ( in the age we live , where everyone travels , it's a must ! ) and also something that would be installable in the bathroom without needing any plugs. ( I , for one , do not have ANY plugs in the bathroom , or , at least any that are working , LOL ) And it would work with a battery ( with the ability to be switched on when you get to the bathroom to save up battery juice ! ) but maybe I'm dreaming.Who knows.

I'm researching my next options to be honest.I'd love to have money to fully outfit my condo , but I had only enough money for one door transmitter , and I'm planning to get another for the buzzer , sometime soon.Then next, who knows , it'll be based on what I'll learn.
