Wired Router for Small scale deployment

[superczar]

We are in the process of upgrading an old analog camera system in our gated community to a wireless IP based one.
The attached network topology should help:
In summary, we have a central server connected to 3 blocks via point-to-point wireless backhaul (5ghz) and 2-3 cameras in each block connected via a 2.4ghz AP in each block

The total bandwidth requirement per camera will be around 2 mbps yielding approx 6-7 mbps of constant traffic from each block

The total number of devices on the network will be approx 25 full time (9-10 camera, 6 backhaul CPE, 4 Outdoor AP, 1 server, 1 NVR, 1 spot monitor )
In addition, I would expect 20-25 end users with a max concurrent of perhaps 10

Coming to the question:
a) My equipment supplier has suggested TP - Link ER5120 for the central router. While it is not really expensive, I am not sure if it is the right choice, esp since we don't have any WAN load balancing requirement

b) Any other wired routers I should look at - with stability being the key requirement

c) Just wondering if it may be worth looking at a prosumer wireless router like Netgear R7000 or Archer C7 given the relatively modest traffic - I can switch off the wireless radio to use it as a wired router or maybe even keep radio on to improve coverage in the community center area

d) Are low end business routers like the ER5120 or even the Cisco RV042G significantly better than prosumer wireless routers?

Unless you have internet service above 100 Mbps, most any router will keep up with that level of traffic.

I would go with the recommendation of the company that designed and installed the network. I assume they will be the go-to if something goes wrong.

Make sure as much of the equipment as possible is on UPS. Power surges are not kind to networking gear.

Internet service is 40mbps ..
In any case, I was more concerned about the router getting swamped with local LAN traffic..

Although I would guess that any good quality prosumer grade gigabit router should be able to handle 25-30mbps constant traffic on LAN and maybe another 20-30 mbps on WAN at peak loads + 30-35 clients with ease..
That's what I wanted to confirm.

The recommendation is from the local TP-Link distributor who is supplying the equipment.
The design and install is up to us.

PS: Thanks for the tip on UPSs.
We do plan to have a 1KVA UPS for the server room and cheaper 600VA for each of the nodes

LAN traffic goes through the router switch and doesn't touch the routing engine. All gigabit switches 16 ports and under today can support wire-speed between all ports simultaneously.

Yes

I think thiggins recommendations are solid on the router question, but I'd really see if you can use moca 2.0 over your existing analog cabling vs going wireless. Wireless security systems are very easily defeated with wifi jammers readily available.

I think any new router can handle 25 or 30 meg of internet traffic.

With that being said I have a ER6120 router in the box which I ran for a year or so which I really need to sell. It is close to the ER5120 router. If you are interested in it I can list it or put it on eBay. How does $75 dollars sound.

My preferred setup is to use a layer 3 switch for local traffic but it is harder to setup.

When using IP based surveillance cameras, ensure that you're getting them from a reputable vendor.

I still prefer the analog cctv cameras over coax myself, going back to a DVR that can be networked. Must less traffic on the lan then.
