Lntech Redefines HD Surveillance with Groundbreaking 500m EX-SDI Technology

In an industry dominated by the relentless advance of IP cameras and analog HD solutions, Lntech Electronics has boldly reasserted the value of pure, uncompressed digital video with the launch of its revolutionary EX-SDI series, successfully achieving 500 meters of real-time, high-definition transmission and shattering the cost and distance barriers that have long hindered SDI technology. This breakthrough positions Lntech as a pioneering force, offering a powerful alternative for applications where latency and image integrity are paramount.

SDI technology has long been celebrated for its real-time, uncompressed video, superior image quality, and strong compatibility, making it a benchmark for digital HD. However, its high cost and limited transmission distance (traditionally around 100 meters) left it vulnerable to the rapid rise of IP and analog HD solutions like CVI and TVI. Lntech's EX-SDI series directly addresses these weaknesses, offering a transformative solution that expands the technology's practicality and appeal.

At a live demonstration, Vice President Ye Dangsheng showcased the flawless video output over 500 meters of standard RG-59 coaxial cable--with zero latency or compression artifacts. General Manager Gordon Guo detailed the two innovative approaches making this possible:

1. The Universal Adapter Solution (TX500/RX500):
   A standalone transmitter/receiver pair that empowers any existing HD-SDI camera on the market to achieve the 500-meter reach, protecting prior investments and offering immediate upgrades.
2. The Native Integrated Solution:
   Featuring the advanced EN331 chipset (developed with Korean partner EYENIX) embedded directly into Lntech's EX-SDI cameras and compatible DVRs. This creates an elegantly simple, all-in-one system with no external hardware, built around a 773V ISP module that guarantees pristine image quality.

The EX-SDI series (1.3MP and 2MP) leverages superior CCD sensor technology to deliver exceptional performance in demanding scenarios. Its intelligent LED IR correction, advanced WDR, and fog-penetration capabilities make it ideal for:

• High-speed traffic monitoring &应急指挥 (Emergency Command)
• License plate recognition in challenging lighting
• Specialized fields like medical endoscopy (visualizing internal details), aquaculture monitoring (tracking fish feeding), and retail loss prevention (recording transaction details), where IP camera latency is unacceptable.

"For too long, SDI's potential was locked away by high costs and engineering limits," stated Gordon Guo. "While others competed in a red ocean, we focused on perfecting SDI. Our 1.3MP EX-SDI camera can outperform a 2MP IP camera in clarity and realism, and its real-time nature is irreplaceable for critical functions."

A key advantage for the retrofit market is seamless analog-to-digital upgrades. Existing coaxial cable infrastructure can be reused, requiring only the replacement of cameras and DVRs--a massive saving in time and cost compared to the rewiring needed for IP systems.

A major hurdle has been the exorbitant cost of signal boosters. Lntech's breakthrough includes slashing the price of a transmitter/receiver pair to a mere $17 (120 RMB), down from the traditional cost of thousands, fundamentally changing the economics of long-distance SDI deployment.

Lntech is committed to a strategy of "Quality First, Value-Driven" to increase market adoption. The company believes that fostering a collaborative ecosystem, rather than operating in isolation, is key to driving the widespread acceptance and scalability of SDI technology. The next milestone is already on the horizon: a 3-megapixel EX-SDI model set for release next month.
