Video-ovisilmukkapuhelinsarja Hikvision TVI-VIS-04 4-johdinjärjestelmä 7 tuuman näytöllä

Hikvision Video Intercom Kit TVI-VIS-04 is a wired 4-wire video door entry system supplied with a 7-inch indoor monitor. The kit provides audio and video communication between an outdoor station and the interior unit, enabling visual identification of visitors and call handling. Designed for residential and small commercial installations, the compact 7" monitor supports straightforward operation and integration into a wired access control setup.

Advantages

The 4-wire connection ensures stable audio and video transmission with reduced interference compared to wireless alternatives. The 7-inch monitor offers a clear, compact display for visitor identification without occupying significant wall space. As a wired system, it provides reliable performance and consistent power delivery suitable for continuous operation. The design focuses on practical usability: simple call answer/end functions, visual confirmation, and compatibility with typical door release mechanisms used in controlled-entry environments.

Suitable for

• Single-family homes and apartments requiring a wired door entry solution
• Small offices and reception points needing basic visitor identification
• Buildings where a compact indoor monitor is preferred for limited wall space
• Installations that prioritize stable, interference-resistant wired communication

Key specifications

• System type: 4-wire wired video intercom
• Indoor display: 7-inch color monitor with touch or button controls depending on model configuration
• Audio/video: Two-way audio communication and live video feed from outdoor station to indoor monitor
• Power and connectivity: Wired power and signal transmission over the dedicated 4-wire bus

How to use

Install the outdoor station at the entrance location and mount the 7-inch indoor monitor inside the premises at a convenient viewing height. Connect power and signal lines using the 4-wire bus according to the installation manual, ensuring correct polarity and secure connections. Once powered, the system allows incoming calls from the outdoor station to ring the indoor monitor; accept the call to initiate audio and video communication, confirm visitor identity on the 7" screen, and operate the door release through the monitor controls when required. Regularly check cable terminations and the monitor interface to maintain reliable operation.

Recommendations

For optimal performance, route the 4-wire cable away from high-voltage power lines and strong electromagnetic sources to minimize interference. Use appropriately rated cables and secure connections at both the outdoor station and indoor monitor. For properties with longer cable runs or multiple stations, consult installation guidelines to verify signal integrity and consider using recommended cable gauges. Perform periodic functional checks of the audio, video, and door release functions to ensure continued reliable access control.
