We got the Babysense Max View two camera monitor 5.5 inch screen. Future proof yourself, you don’t need to have the second camera on as it works with just one but if you ever want to go round 2 then you’ll have it ready to go!
Vtech VM3263 I’ve not used it but it’s the one I’m going for, currently in Argos for £50
I've gone for this one - https://amzn.eu/d/5moPXQD
Babysense Prisma
We've got this one, https://amzn.eu/d/3T9LDKW (hello baby HB6081) only had a brief play with it so far as baby hasn't arrived yet. Seems good, only weird thing we noticed is our smart meter reader wasn't connecting while the baby monitor was on.
BT6000 x cheap to buy online can connect multiple cameras if needed to one monitor can move set cameras using the monitor rather then manually adjusting it x also doesn’t require WiFi
