Description
Broadcast-quality Audio
In video surveillance systems, audio information is used as additional evidence. The HDCVI camera supports audio signal transmission over coaxial cable. In addition, the use of a unique sound processing and transmission technology, noise elimination guarantees the quality and efficiency of the collected audio information.
4 signals over 1 coaxial cable
The HDCVI technology supports simultaneous transmission of 4 types of signal: video, audio, control and power over coaxial cable. Two-way data transmission allows the HDCVI camera to interact with the HCVR transmitting event information or control. Also, cameras of the S3 series support PoC technology, power transmission over coaxial cable.
Long-distance transmission
The HDCVI technology guarantees real-time transmission over long distances without any loss. Supports transmission up to 800 meters at 1080P Full HD resolution over coaxial cable, and 300 meters over UTP cable.
* Results confirmed by real-time testing in the Dahua laboratory.
Ease of use
The HDCVI technology inherited the feature of easy installation from the traditional analog video surveillance system, making it better when choosing video surveillance systems. The HDCVI system can provide a smooth transition from a traditional analog system without replacing existing cables. The plug & play approach allows for effortless configuration of video surveillance networks.
Multi-formats
The camera simultaneously supports HDCVI and CVBS signal from two BNC connectors. Independent outputs facilitate camera setup with a test monitor during installation, and the signal can also be split to an analog security monitor input.
Protection
The camera is protected against water and dust with an IP67 protection rating, making it suitable for indoor or outdoor installation. The camera is designed to operate at an ambient temperature range of -40 ° C to + 60 ° C. The camera supports protection against input voltage ± 30%, suitable for operation in unstable power conditions. It has lightning protection of 4kV.
