Best WiFi & CCTV setup

Hi,

Looking forward to spending max ₹25,000 on full networking setup for a commercial space. The coverage area is flat 2000 sq ft.

Hardware Requirements: 2 IP CCTV Camera (Max 4 in future) PoE Hub WiFi Router / Mesh Cat 6 wiring NVR HDD for Recording

Software Requirements:

• IP Cameras should be secure and accessible remotely.
• High Quality cameras. (Megapixels are not the focus)
• WiFi network should allow easy Guest access. (Expecting several new people everyday)
• WiFi network should be fast. Input speed will be upwards of 100mbps via optical fibre. (Airtel/Jio)

Please suggest a setup which fits the budget.
