گیرنده صوتی تصویری برد بلند COFDM 2W برای ربات ها

Q: Q1: What’s the range of COFDM 2W Long-Range Video Audio Transceiver?

A1: Typically 1–2 km near the ground, and up to 4–8 km in clear LOS conditions (depends on environment and antenna height).

Q: Q2: What is the system delay?

A2: Video + Audio latency: 150–300 ms ; Data latency: ~40 ms .

Q: Q3: Can it support two-way data?

A: Yes. It supports bidirectional RS232/RS485 data and two-way voice intercom simultaneously.

Q: Q4: Can it be made smaller or lower power (2W)?

A: Yes, a compact 2W version (13×10×3.7 cm) is available.

Q: Q5: Why does video blur when moving fast?

A: It’s caused by dynamic video compression — a trade-off to maintain real-time low latency .

Customer Inquiry about COFDM 2W Long-Range Video Audio Transceiver for Robots

“I’m looking for a transmitter and receiver, COFDM با صدای دو طرفه و ویدیوی یک طرفه, برد طولانی, I think 2W might be fine.”

This is a very typical inquiry from professionals working with روبات های زمینی, remote vehicles, and mobile command systems, where reliable long-range video and audio communication is essential. Let’s break down the requirements and the perfect product that fits them.

Quad Video Transmitter with Data Audio Transceiver for Robot or Mini Remote Operated Vehicle — فرستنده چهارگانه ویدئویی با فرستنده صوتی داده برای ربات یا وسیله نقلیه مینی از راه دور

Understanding the Customer’s Needs

The customer clearly wants:

تکنولوژی COFDM for robust, anti-interference transmission.
صدای دو طرفه for live communication between operator and robot.
ویدئوی یک طرفه to send clear, low-latency visuals from robot to operator.
2W انتقال قدرت برای medium-to-long range عملیات (1-2 کیلومتر, even close to the ground).

Such a setup is typically used in سگ های ربات (در UGV), bomb disposal robots, و inspection vehicles, where maintaining real-time video, کنترل کنید, and voice contact is critical.
