RS485 is a standard defining the electrical characteristics of drivers and receivers for use in balanced digital multipoint systems. Herein picture is the RS485 Connection circuit diagram for the Panasonic Unitized Dome Camera.
You should use a shielded-twister pair cable, low impedance, and wire gauge size is thicker than AWG #22 (0.33mm2) for RS485 site communication.

This is a miniature module of Narrow Band Transmitter and Receiver UHF Radio which is used to be applied in vehicle
telemetry systems, wireless networking, wireless security system and panic attack facility. Both modules are ideal for use in portable battery powered wireless applications since its small size and low power requirements.
The circuit diagram shows how the FM narrow band transmitter and receiver modules can easily be integrated into a system to form a wireless link. In the datasheet you may find transmitter and receiver connection diagram, pin description, functional description, frequency channels, and the design and positioning of the antenna.
