I have a WiFi Control based Camera Device. I want to make a PCB with ESP8266 which will connect with the Camera via WiFi and Extend the Range. Two ques please ...

-1. I like to ESP-02 as it have U.FL Connector so east to connect a External Antenna. What max possible WiFi RF Range (Line Of Sight) I can get from ESP-02 using a SMA WiFi Antenna?

-2. What configuration I need to apply to Module to act it as a Range Extender?

Thank you in advance.

Rereads.

You could write a custom firmware to manually receive packets and resend them to a different host, but honestly I don't think the ESP8266 is the right choice for this application (that solution might not be fast enough for video).
You could save a lot of time & effort by either using directional antennas or getting a cheap wifi repeater/AP.

I modified the NodeMCU firmware to forward IP packets and to set a DNS server via DHCP. I then put the ESP8266 into StationAP mode and connect it to my home Wifi network. I also run a simple DNS forwarder .lua script.
A client connecting to the ESP can then connect through to the home network or the internet, provided you set a route to the ESP8266's subnet in you default router.
Here's the video with the link to the firmware and scripts. https://youtu.be/NH1rjk3Q_MU
