HD-TVI cameras new technology for an analog HD solution
Even we enter into the digital era, analog surveillance technology doesn’t stop its innovation. Besides the HD-SDI and HD-CVI (in-house technology of Dahua), today the Hikvision and other camera manufacturers announce HD-TVI cameras release. HD-TVI means High-Definition Transport Video Interface, HD-TVI is based on traditional coaxial cable for video and data transmission, it supports not only 720P/1080P video signal but also includes audio, data signal over long distances up to 500 meters.
At present, there are approximately 100 million coaxial cables are deployed for analog camera connections. In the next 3-5 years, they will be replaced with a high-definition camera. However, some users start to worry they have to rewire, re-install or add new network devices for upgrading. This group of users prefers the economical and easy solution to upgrade an existing system to HD, rather than adopting the IP camera. In this context, the HD-SDI and HD-TVI technologies were born.
Turbo HD products support High-Definition Transport Video Interface (HD-TVI) technology that allows users to send uncompressed, high-resolution video over coaxial cable. Overcomes challenges of HD video over coax methods which were limited by cable type and distance, reliability, lack of bidirectional communications, and total system cost.
Among current HD solutions, the distance of transmission, compatibility, and cost are always problems for both manufacturers and users. In this context, HD-TVI technology as a brand-new analog HD solution emerges in the market. Overall, the HD-TVI technology can provide a more economical, easier to install and use solution for high-definition analog surveillance systems.
The HD-TVI can convert digital signals to an analog signal for expanding its transmission distance, lower total cost, reducing total video storage space. Through coaxial cable, the video transmission distance can reach up to 984 ft (299.92 m) – 1640 ft (499.87 m) meters without obvious video quality loss. In addition, the HD-TVI can transmit CVBS 75Ohm analog video signal with a resolution of 720P and 1080P at 30fps, which are difficult tasks to adopt other HD coaxial solutions. Merely replacing the existing analog camera and DVR with latest HD-TVI camera and DVR, users can upgrade their surveillance system to a brand new 1080P HD system, this doesn’t require extra installation knowledge and cost.
- Send uncompressed, high-resolution video over coaxial cable
- HD-TVI promises the absence of video delay in the live viewing, bidirectional signaling, and efficient storage
- Turbo HD supports up to 1080p resolution at distances over 1500 feet (457.2 m), the HD-TVI signal is especially immune to electromagnetic interference
- Live video can be viewed in high resolution with zero latency because the video stream is uncompressed.
- Bidirectional signaling allows for PTZ control and setting camera functions remotely
- Turbo HD products such as the 2CE56D5T-VFIT3 1080p EXIR Varifocal Turret and the DS-2CE16C5T-IT1 720p EXIR Fixed Lens Bullet provide high-definition megapixel video that installs as easily as standard analog CCTV products
- The smart search feature is another key selling point, as is the Tribrid technology
- Tribrid DVRs can save data from standard definition analog cameras, IP cameras, and HD-TVI cameras simultaneously
- 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
Integration: DVRs are compatible with multiple video formats, from standard definition analog to HD-TVI to megapixel IP
