Product Details

Specifications

1) Long range data transceiver for industrial use, up to 20~30km;
2) RF power: 20W, TTL, RS232 (or 485), customized.

Wireless PTZ Controller for Speed Dome Camera

Product Model: SG-F408

Application:
Generally, there are three important points must be emphasized:

1 The communication interfaces are the same standard RS485 / RS232 interface;

2 The same baud rate at 2400bps;

3 Terminal access method and the commonly used method of cable access must be in the same parity bit.

Special Features:

1	Transfer rate: 2400bps, compatible voice or data signal transmission
2	Can be set 256 Spots, the channel spacing is 25KHZ (standard)
3	Integration of transceiver, both digital and analog signals can be send and switch quickly
4	Either co-frequency or unco-frequency in air transmission
5	Double loop and VCO structure, high stability
6	Use 30W imported power amplifier module
7	Use standard TTL, RS232 (or 485) level, convenient to connect to the control keyboard or personal computer directly
8	SMT design, stainless steel outshell, miniature size and easy to install, can stick heat sinks
9	Testing methods is in accordance with Mobile Communications “90” standard
