I think the messages on this thread are clear. I will add what i think consolidates this:
-
A lot of people want to use modern alarm systems like Ring. They are pretty awesome.
-
The current professional and domestic alarm companies provide this feature (external sirens), but let’s be honest, their smart features are clunky at best. I’ve done my research and have one of the (if not the best) uk alarm system, and they suck, hands-down, at investing and integrating into a modern ecosystem.
-
Typical home alarm systems do not cater for modern (easy to use) users. I don’t want to have to pay 1000 for a contractor to come and install an alarm and configure an obscure configuration which i cannot change or turn the alarm off at 3am. (I know some of you have been there!).
-
Traditional alarm companies don’t have the investment to develop and listen to their customer base. They have good employees who would love to, but they’ve missed the bandwagon and need to invest or die out slowly.
-
I will give a plus to some traditional companies for trying to modernise, but you guys aren’t doing enough… in development, marketing and most importantly security and reliability. I mean if not that then what?
-
Ring isn’t on thin ice, they are on thick ice. They are modern, integrate with modern devices and actually have a roadmap they communicate (well maybe not… but should) accurately.
-
Ring is, i believe, backed by the world golden standard for infrastructure, AWS. Ermm, your local alarm company is using mostly their own ISP, cool. Maybe they use public cloud and can diversify more, but do they? I doubt it.
-
Am i a ring fanboy? Yes and No, not really right now (I have 3 devices and would like more but…), they need to communicate their roadmap better and provide insight. Honestly, customers want to be excited by developments coming. They want to know their products will be updated soon and will still buy them even if they aren’t available yet. I would suggest just opening their roadmap with their ideas, a bit like kickstarter, people invest in that! Marketing needs to embrace this and not hide behind a possibility it might not happen. Zzz.
-
Ring devices should link together in an alarm situation. I completely agree with this. No need for an external siren if your multiple floodlights turn on and alarm. Easy to solve i reckon and is probably already saved in their roadmap to sell more. They shouldn’t do this, but… they will. A bit like Apple. Buy next, buy next…
-
What competition, i reckon check the competitions margins vs Ring.
-
And finally, you shouldn’t have to use external automation to provide the features you need. If you do, then you should be able to read a roadmap and wait, or move away from ring to somebody who gives you the features you need.
Ill keep buying this product as long as it gives me the features i need
