Hello, @Info
I will give you different suggestions because I don't know your environmental factors and your goal.
WLAN has 3 different standards now. WLAN 4, WLAN 5 and WLAN 6. Please check the WLAN standard of your cameras first. WLAN 4 (11n) is an old technology with low price. I recommend you to buy WLAN 5(11ac) or WLAN 6(11ax).
WLAN 4
TL-WA850RE 4.1/5.0
It is not recommended, but it is an option.
Tp-Link TL-WA850RE (300Mbit/s)
WLAN 5
RE450 4.3/5.0
This product has a good and stable performance without too high price. It's very easy to set up and has good coverage.
Tp-Link AC RE450 (1300Mbit/s, 450Mbit/s)
Wi-Fi 6 is the latest Wi-Fi standard, now more and more devices support Wi-Fi 6. Wi-Fi 6 also provides better coverage and faster speed for your device that only supports Wi-Fi 5.
WI-FI 6
RE505X 5.0/5.0
Tp-Link WLAN mesh repeater RE505X (1200Mbit/s, 300Mbit/s)
All of these repeaters can work with your router. Have a nice day.
