Answer:
The DS-KIS202T utilizes a 4-wire bus (video, audio, power, ground) supporting RVV4 cable runs up to 100 meters: RVV4 0.2 mm² for ≤10 m, RVV4 0.5 mm² for 10–30 m, RVV4 0.75 mm² for 30–50 m, and RVV4 1.5 mm² for 50–100 m.
The Hikvision DS-KIS202T interconnects the outdoor station and indoor monitor via a dedicated four-wire interface carrying 1-channel video input, 1-channel audio input/output, 1-channel power supply, and 1-channel grounding. The kit package includes a 5-meter pre-terminated patch cable for basic setups, but field installations over longer runs must select RVV4 multi-core conductor gauges according to transmission distance (TD):
- TD ≤ 10 m: RVV4 × 0.2 mm²
- 10 m < TD ≤ 30 m: RVV4 × 0.5 mm²
- 30 m < TD ≤ 50 m: RVV4 × 0.75 mm²
- 50 m < TD ≤ 100 m: RVV4 × 1.5 mm²
Utilizing wire gauges smaller than specified over long distances causes signal attenuation, video interference, and degraded audio levels. Power leads must never be terminated to the video or audio pin contacts, as this will result in permanent hardware circuit damage.
