First, as Charles says, you need to study the Datasheet for the Camera - that will tell you:

What UART output signal(s) the camera provides;

What UART input signal(s) the camera requires;

The voltage, timing, and other requirements of those signals.

Then you need to study the Datasheet for the Microcontroller - that will tell you:

What UART output signal(s) the MCU provides;

What UART input signal(s) the MCU requires;

The voltage, timing, and other requirements of those signals.

With that information, you will know whether the Camera's UART can be connected direct to the MCU's UART, or if some interface circuitry will be required.
