Extension or additional product that replaces the POE injector with a POE injector with a mini UPS inside.
We have a fair few installtions with the following setup where it would be useful to survive a 10min+ power outage, if only to upload the footage.
injector > nano switch > mesh point + unifi camera.

24v, in a similar form factor to the nano switch, but replacing the POE injector.
Dont know what the EP-24v-72W is because its a hidden beta, but it does sound promising. However I notice the EP-54v-150W is not a UPS i.e. it doesnt have a battery backup.
Like this https://www.msdist.co.uk/mikrotik/power-over-ethernet/mups#Product-Specifications but with more WATTS and in the UK please. That price is silly, I would expect it to be in the £100 ball park.
Mains in, 802.3af out with battery backup with enough watts to run 1x nano, 1x mesh, 2x G3 cameras.

These are indoor devices. Steel chassis with a half-width rack format. Two Ethernet ports with switchable PoE plus two high current DC outputs (5.5mm barrel jacks via terminal block), and UNMS support.

Both versions provide battery backup via a user-supplied 12V SLA battery. Choose the size based on your load and holding time requirements.

What would be cool with a backup POE injector is for it to be a mini Lithium battery in side the poe injector that makes it able to hold up a 5-10w load for a few minutes. Enough to holdover for small outages less than 15min. For the battery think 18650 size (about 7-9Wh capacity) so that it is user replaceable.
24V would be a great starting point but 48V would work as well as you can use the existing converters.
Even better would be a "HD" Version that had 2 POE ports so that you can easily have an AP and a camera for example, with only 1 AC cord. Note I done mean a switched device just back to back injectors in the one case. I would love one of these with out a battery as well...
An outdoor version would be neat as well, with built in battery.
