I am not worrying about how camera feed will be transmitted. My concern is only to move the camera in different directions using pan and tilt mechanism. And also it may not be camera some other sensors. but for me I just need to control it's movements.
No. I am not worrying about how camera feed will be transmitted. My concern is only to move the camera in different directions using pan and tilt mechanism.
I have non line of sight conditions will it be work. And is there any modules available in market for this system?
Use two servos and a proper mechanics.
Then get a couple of LoRa modules, a 3.3V Arduino, and do some link testing.

Note that you only need to give the reply once; everyone can see every post - you don't need to repeat it.
Anyhow, if you have got a link for transmitting the camera feed, is there not any way that you can also use that same link for the control signals?

I am looking for 1Km not 1000Km. And I am from India.

Surely any (or most) internet technology (including lorawan) can be used to create a small “private network” that is not dependent on the world-spanning capital-I Internet…
For instance, I think there are projects that use ESP based modules as short-range WiFi intercoms, without attaching to The Internet.

You can consider NRF24L01 2.4GHZ Wireless Module (1KM).

Can you please suggest any best ESP modules which can deliver 1Km range Wi-Fi.
Thank You
Line of sight in perfect conditions might be possible.
Non-line-of-sight, forget it.
How is the testing with LoRa going ?

Thanks to letting know. I want to purchase these LoRa module
https://robu.in/product/esp32-lora-sx1278-0-96-inch-blue-oled-display-bt-wifi-module-for-arduino/. Hope it will work in my condition. What's your thoughts in it.
And I have a small doubt. LoRa having some restrictions on message limit and duty cycle right. So, If I want to control stepper motor, will these rules apply?
Read the data sheets.
Should work, although you would need to use a better antenna, you can get u.fl to SMA socket adapter cables.
However, at extreme range settings you could loose a bit of range since the ESP32 being a faster processor creates a fair bit of RF interferance. A 8Mhz\3.3V Pro Mini and LoRa module would be better.
Duty cycle limits will apply to all types of RF comms at a particular frequency.
Details vary depending where in the World you are, but I cant think of anywhere which has legal restrictions that apply specifically to LoRa.

Can you please elaborate on this. Are you mentioning about Arduino pro mini. With some SX12__ LoRa module. And how much Db antenna should I have to choose?
A Pro Mini is a small low cost Arduino, available in a 3.3V version so it can be directly connected to the LoRa module.
The Pro Mini has 0.1" spaced pins and various people, Adafruit for one, make LoRa modules that also have 0.1" pins.
Wire it all up on a bit of 0.1" strip board and away you go. If you use 0.1" socket headers, of the type you see on an Arduino UNO, you will be able to easily remove the Pro Mini and LoRa board from the stripboard and use elsewhere.

Not just LoRa - it's any use of the unlic3ensed ISM bands.
Of course they will. It's purely about spectrum use - the application is entirely irrelevant.
