TA-509 is Our core research and development of a completely independent multi-2.4G digital wireless transceiver digital voice and video intercom, It using long-distance wireless data transceiver modules Voice .The latest high-performance RF radio chip and industrial-grade processing chip . Equipped with a small amount of external components , Such as audio amplifier,microphone,speakers,etc.And using industrial-grade design standards, work together to build a multi-functional wireless digital intercom products.


Basic Functions


1. Using a digital public 2.4G ISM band: 2402 ~ 2483.5MHz.

2. The air transfer rate of up to 2Mbit / s, greatly reducing space

delivery time

3. Using ARM7 core, super-computing power.

4. With 12-bit digital audio signal Serial Input, DAC audio output port,

the sampling rate 8Kbps.

5. Image data transmission and voice transmission data synchronization.

6. Full-duplex voice mode.

7. Image using MJPEG compression, one-way wireless up to 10 ~ 16 / sec

8. Transmit Power 16-20dBm, receiver sensitivity of-100dBm.

9. Communication from the open area up to 500 meters.

10. Using AFH adaptive frequency hopping technology, with wireless LAN and Bluetooth devices at the same time share the 2.4G frequency bands.

11. Auto power-saving sleep protection,

internal and external wake-up work.

12. Separate external power supply,

wide voltage supply range DC3.6V ~ 6V.

13.Randomly generated communication channels and synchronization channels.

14. With a monitoring function, easy operation.

15. Using OV7725 camera, with 2.4-inch TFT display, clear image and clear picture.

16. Completely independent core technology , low-cost advantages,

we can provide software upgrades without changing the hardware
