| Functions | Description |
|---|---|
| Smart IR Illumination | The camera ensures optimal performance in low light conditions by providing IR illumination, guaranteeing uniform brightness in B/W images. Using smart IR technology, it adjusts the IR LED intensity to compensate for varying target distances, preventing image overexposure as targets move closer to the camera. |
| 4 Signals over 1 Coaxial Cable | HDCVI technology supports the simultaneous transmission of 4 signals (video, audio*, data, and power) over a coaxial cable. Bidirectional data transmission allows interaction between the HDCVI camera and the XVR for actions such as sending control signals and triggering alarms. HDCVI technology also supports PoC, simplifying camera installation. *Audio input available for select HDCVI camera models. |
| Long Distance Transmission | HDCVI technology ensures real-time, long-distance transmission without loss. It supports distances up to 700m for 2-MP/5-MP/8-MP HD videos through coaxial cables and up to 300m through UTP cables. These results have been rigorously tested and verified in Dahua’s test laboratory. |
| Protection | IP67 certified – the camera successfully passed rigorous dust and immersion tests, ensuring functionality in dusty and waterproof environments. It can operate normally even when submerged in 1m deep water for up to 30 minutes. The camera exhibits ±30% input voltage tolerance for certain power supplies, making it suitable for various outdoor scenarios due to its wide voltage range. |
| Multi-language OSD | Multi-language OSD: The OSD provides multiple functions for diverse monitoring needs, offering features like backlight mode, day/night mode, white balance, privacy mask, and motion detection. It supports 11 languages: Chinese, English, French, German, Spanish, Portuguese, Italian, Japanese, Korean, Russian, and Polish. |
| Simplicity | HDCVI technology maintains the simplicity of traditional analog surveillance systems, making it an excellent mechanism for safeguarding valuables. Upgrading from the traditional analog system doesn’t require replacing existing coaxial cabling. Its plug-and-play design facilitates high-definition video production during surveillance without the need for network configuration. |
