If going for Omada, don’t go for EAP610, the coverage is abysmal. You’d need to get EAP650 or higher. I was previously using an EAP610 and then switched to EAP670.
Avoid the OC200 controller - it is not going to be future proof plus is slow. Rather run your own controller on Raspberry Pi or the equivalent, or use the free Omada Cloud Essentials. The latter will mean that for most changes, you are relying on the cloud.
I have a UCG Ultra + U6+ AP. The UCG Ultra is significantly more capable than any TP Link Gateway, especially if you want good firewall features and IPS/IDS/VPN. TP Link does not mention the hardware of their gateways, Unifi does. Unifi is typically more proactive with security updates, they have an active bug bounty program while TP Link does not.
On the other hand, the U6+ is nothing to write home about. They are pretty much comparable to Omada AP, but it costs roughly the same too.
Unifi switches and cameras I feel are overpriced. If you already are on the Unifi ecosystem, they give you a nice centralized place to manage stuff, especially for switches, but otherwise there is no advantage over say TP Link switches at half the price.
You don’t need a Unifi switch for 2APs in any case - you can get 2 POE injectors or a cheap TP Link PoE switch. So UCG Ultra + 2x U6+ + 2x POE Injector = 40k roughly.
Both can be managed locally. Unifi should have better long term support for their devices with firmwares. TP Link is notorious for not updating the firmware of their old devices. They release multiple versions of the same product and drop support for the older versions.
I personally bought Unifi because of their better firewall, security posture and a longer term product updates. The only product I can say is absolutely worth is the UCG Ultra. You can do a lot more with it than TP Link. For example, a couple of things I use: Put your IoT devices or cameras on a separate VLAN. The IoT VLan cannot access the Main VLAN, they can only reply back. You can run a VPN Client running on the router, and map a SSID to that VPN connection so if you connect to the SSID you automatically get routed over the VPN. Not sure TP Link supports these use cases.
The only thing I would add is that the primary reason to go this route over a reg router is when you want to add multiple APs so that there is at least one in LoS from all corners of your house.
I see you have added plenty of equipment for both options but a single AP which makes the whole upgrade (?) kinda pointless.
Do not assume that one of these APs will somehow give you better range/coverage than a standalone router - it simply won’t.. If anything, it will likely be less
Yes, for now I’ll be adding 2 access points to keep the budget manageable. Later, I plan to add 2 more once things are more settled, as I’m setting up this house from scratch and purchasing everything it needs.
