yes this is what i use currently, but my modem is kinda cheap (rm1xx model) and not strong enough.
mi wifi 3 good with 20 meter?
Is the camera or the router placed behind any pillar, blocking the wifi signal? What is your current router? Mi Wifi 3 is not particularly powerful but 20m with clear line of sight without anything blocking is no problem. My recommendation for Mi Wifi 3 is if it flashed to Padavan firmware as it the cheapest wifi router with OpenVPN support and pretty OK wifi performance. If you don't need OpenVPN & ok with chinese UI, then you don't need to flash it to Padavan firmware.

anything below rm300.
maxis wireless broadband, 5gb quota.
mii fi 3 recommended by forumer above seems good, but if there is better choice let me know
If you want something that are more powerful & better receive sensitivity, then there is mikrotik RB951Ui/RB951G. There are other high power router within that budget, but I suggest you get one with VPN server functionality if you ever intend to access it remotely. Avoid using port forwarding. If you only going use it to let the CCTV to send email and upload event footage, then any high power router will do.
