HD SDI DVR & Cam: Security Camera Surveillance System

HD TVI DVR & Security Camera Services

The HDTVI solution can enable customer to setup a complete analog surveillance system with advantages of long distance transmission (500 meters) through coaxial cable. This new technology enables user to upgrade their existing standard resolution analog system with HD-TVI compliant cameras and DVRs.

CCTV users can enjoy HDTVI(High Definition Transport Video Interface) solution without investing huge amount of money in rewiring the existing coax cable infrastructure. The top-notch HDTVI camera can deliver latency-free 720P/1080P high definition video over up to 500 meters.

HD security camera

The new HDTVI technology support UTC function which can allow user to remotely control the OSD menu and PTZ control via coaxial cable. This means user can quickly install and adjust the camera without accessing the camera itself.

HD-TVI systems are easy-to-install using existing coaxial (RG/59, RG/6 and RG/11) cables without an adapter, which reduces cabling costs and simplifies installation. HD-TVI technology also enables you to zoom in on live video and playback modes to focus in on an area of interest with exceptional clarity and crisp detail, which is ideal for license plate and facial identification. Our true HD hybrid security systems allow you to use existing analog CCTV equipment and provide the ability to add HD cameras as your budget allows, which saves you money.

HD Security SystemsUsers can upgrade their surveillance system to a brand new 1080P HD system, this doesn’t require extra installation knowledge and cost.

  • Analog HD high video quality 720P/1080P resolution
  • Transmit video and audio signal, and data signal over coaxial cable
  • No quality loss and delay for HD video transmission
  • Impressive long distance transmission capability
  • Easy to upgrade your existing analog system to HD system


Here are 10 reasons to choose HD-TVI technology for your next surveillance application:

Megapixel Resolution

High-definition (HD) images provide forensic detail and zoom capabilities for facial recognition and license plate identification. HD-TVI produces high-resolution megapixel images and enables you to zoom in on video for closer forensic inspection.

Simple Installation

No IP-networking required! HD-TVI installs as easily as a standard analog CCTV camera or analog video security system. HD-TVI does not require a complex network infrastructure, so installation time is much quicker than installing an IP video security system.

Lower Cost

HD-TVI solutions offer megapixel resolution at a fraction of the cost of a comparable megapixel IP solution. Because HD-TVI security solutions do not require a complicated, expensive network infrastructure (like IP solutions require), they provide a much more cost-effective megapixel resolution security solution than a comparable IP security solution.

Zero Latency

Monitor video in real-time, without the transmission delays commonly found with IP solutions. The live video you see is actual video without any lag time, so you will never miss seeing important video due to a delay in transmission.

Low Cabling Requirements

Transmit HD video fast and with high signal quality. HD-TVI enables you to use your existing (RG59 and Cat5/6 coax cables or most standard CCTV shielded cabling. The ability to utilize existing cabling to transmit HD video, which saves you money on cabling and installation costs.

Longer Transmission

Transmit HD video up to 1600′ over RG59 cabling – 3x the distance of IP systems. HD-TVI offers the longest distance transmission over RG59 coax and lower quality cabling (compared to other HD Analog formats). This makes HD-TVI the ideal HD format for long distance installations with longer cable runs.

Transition Friendly

HD-TVI is compatible with existing CCTV cameras and existing coaxial cables. HD Analog enables you to use existing equipment, with the ability to transition to HD, when your surveillance needs and budget allows.

Analog Compatible

HD-TVI recorders are capable of recording video from ANY analog camera, on ANY channel, in ANY configuration. HD-TVI recorders are open source, backwards compatible with any analog camera and are not limited by channel or technology.

HD Analog Compatible

Unlike other HD Analog formats, HD-TVI recorders are compatible with ANY HD-TVI camera, regardless of brand. Many of the other HD analog technologies are limited by brand and equipment compatibility.

IP Compatible

D-TVI “Hybrid+” recorders accept a limited number of IP video inputs, on ANY channel, in ANY configuration. HD-TVI Hybrid+ recorders accept analog, HD-TVI and IP cameras, offering greater flexibility when it comes to your security application.
