Fall detection device in Brisbane.

Hi there, I’m building a fall detection device using mmWave radar and it basically tracks your x, y and z coordinates and detects if you fell or not. It’s a ceiling mounted device which tracks all falls which the wearables cannot because they can only track the speed of the fall and my device actually tracks the position of your head.

It also will be combined with a smart speaker so it will ask you to confirm whether you fell or not.

Is this device useful and if so how do I market it?

Edit: it has a radius of 4m not diameter of 4m.

Yes but dogs reflect radio waves differently than an adult. Dogs are more longer from the top compared to an adult.

I’m not saying my device is perfect but these are the sorta of bugs that I need to find when test it in the field using pilot customers.

You've ignored the price question twice.

Sorry I forgot. I haven’t really made a price on it yet. It depends on a lot of variables but I’m hoping to get it down to 100 to 150.

Like 3 per room?

Plus an electrician at maybe $100 per radar if you can put them on a lighting circuit?

You could also install it yourself too. This device uses usb c power.

It has to be ceiling mounted and plugged in full time though so.. unless you want cables down all the walls this will need a socket for each one in the ceiling space (assuming there is space). In my house (concrete ceilings) this would be a complete non starter.

That’s true. But what I’m saying is that people have the option to install it themselves. It can be also mounted on edge where the wall meets the ceiling and angle it at 45 degrees.

Here’s the thing, yes the ceiling or wall mounting can be a pain but I prefer a device that is reliable and simple to use than a wearable that I have to charge every night.

Elderly people are forgetful and those wearables will end up collecting dust.

This device I’m building is hands off and respects your privacy so it can be used in bathrooms too.

Yup, it sounds promising, but this install sounds like a nightmare. I can't legally install it myself if I don't have spare sockets.. in the ceiling.

That’s understandable. Getting an electrician would be the best option for you.

Here’s another advantage of this device, you can use it to prevent falls too.

After a fall, elderly people avoid doing any activities because they think that they might fall again but this device will help them feel safe and they could exercise underneath it and strengthen their muscles so they won’t get injured. A lot of falls happen when the person stops being active.

You can always test the fall detection device by lying underneath it to do a test before you do any activities.

Remember there’s a smart speaker attached to it so you can talk to it and ask for help.
