| Functions | Description |
|---|---|
| 4 Signals over 1 Coaxial Cable | HDCVI technology supports 4 signals to be transmitted over 1 coaxial cable simultaneously: video, audio*, data, and power. Dual-way data transmission allows interaction with the HCVR, such as sending control signals or triggering alarms. HDCVI technology supports PoC for construction flexibility. * Audio input is available for some models of HDCVI cameras. |
| Long Distance Transmission | HDCVI technology guarantees real-time transmission at long distances without any loss. It supports up to 800m(1080P)/1200m(720P) transmission via coaxial cable and up to 300m(1080P)/450m(720P) via UTP cable. *Actual results verified by real-scene testing in Dahua’s test laboratory. |
| Simplicity | HDCVI technology inherits the inherent simplicity of traditional analog surveillance systems, making it an ideal choice for investment protection. HDCVI system can seamlessly upgrade the traditional analog system without replacing existing coaxial cabling. The plug and play approach enables full HD video surveillance without the hassle of configuring a network. |
| Smart IR | The camera is designed with microcrystalline LED IR illumination for optimal low-light performance. Smart IR technology ensures brightness uniformity in B/W images under low illumination. Dahua’s unique Smart IR adjusts to the intensity of the camera’s infrared LEDs to compensate for the distance of an object and prevents IR LEDs from overexposing images as the object comes closer to the camera. |
| Multi-formats | The camera supports multiple video formats, including HDCVI, CVBS, and two other common HD analog formats in the market. The four formats can be switched over through the OSD menu or by using PFM820(UTC controller). This feature makes the camera compatible with not only HCVRs but also most end users’ existing HD/SD DVRs. |
| Multi-language OSD | OSD menu provides multiple image adjustments and function settings to meet the requirements of different monitoring scenes. The OSD menu includes configurations such as backlight mode, day/night, white balance, privacy mask, and motion detect. The camera supports 11 languages for the OSD menu, namely, Chinese, English, French, German, Spanish, Portuguese, Italian, Japanese, Korean, Russian, and Polish. |
| Protection | The camera’s outstanding reliability is unsurpassed due to its rugged design. The camera is protected against water and dust with an IP67 ranking, making it suitable for indoor or outdoor environments. With a working temperature range of -40°C to +60°C (-40°F to +140°F), the camera is designed for extreme temperature environments. Supporting ±30% input voltage tolerance, this camera suits even the most unstable power supply conditions. It’s 4KV lightning rating provides protection against the camera and its structure from the effects of lightning. |
