Answer:
The DS-KIS205T operates on a 4-wire bus carrying video, audio, power, and ground, supporting up to 2 outdoor door stations, 3 indoor monitors, and 1 auxiliary analog CCTV camera per monitor. Each outdoor door station features a dedicated relay to operate 1 electric lock, using RVV4 copper wiring from 0.2 mm² up to 1.5 mm² depending on transmission distances up to 100 meters.
The Hikvision DS-KIS205T is designed around a structured 4-wire analog bus architecture accommodating multi-point entry configurations:
- Core Wiring Interface: 1 four-wire bus per channel providing 1-channel composite video input, 1-channel bidirectional audio, 1-channel 12 VDC power supply, and 1-channel grounding.
- Maximum Topology Capacity: The intercom bus supports up to 2 outdoor door stations and up to 3 indoor monitors interconnected on the same system.
- Access Control Relays: Supports the direct integration of 1 electric door lock per outdoor station (up to 2 locks total across a 2-door station deployment) triggered directly from the indoor monitor buttons.
- CCTV Integration: Each indoor station provides an auxiliary analog video port to connect 1 external analog CCTV camera for supplementary area monitoring.
- Recommended RVV4 Cable Cross-Sections: Transmission distance determines required copper core gauge:
- Distances up to 10 m: RVV4 × 0.2 mm²
- Distances from 10 m to 30 m: RVV4 × 0.5 mm²
- Distances from 30 m to 50 m: RVV4 × 0.75 mm²
- Distances from 50 m up to 100 m: RVV4 × 1.5 mm²
