BCS BCS-ZA4802 transceptor balun de vídeo passivo de 4 canais para AHD/TVI/CVI/CVBS sobre UTP, preto

Running four analog or HD-over-coax cameras across a building, parking lot, or warehouse often means wrestling with bulky coaxial trunk lines. The BCS BCS-ZA4802 eliminates that hassle by letting you connect up to four BNC cameras to a single Cat5e/6 UTP cable run. This passive balun hub is a favorite among CCTV installers and system integrators who value clean, cost-effective cabling for both new builds and retrofits.

Key specifications

• 4-channel passive video balun transceiver
• Supports AHD, TVI, CVI, and CVBS (960H) video formats
• 4x BNC male connectors for camera inputs
• 1x RJ45 connector for UTP cable connection
• Transmission distances: CVBS up to 400 m, AHD 720p up to 300 m, AHD 1080p up to 250 m, TVI 720p/1080p up to 250 m, CVI 720p up to 400 m, CVI 1080p up to 250 m
• 75 Ohm video input impedance, 100 Ohm UTP impedance
• Built-in surge protection
• Compact ABS plastic housing
• Operating temperature: -10°C to +50°C
• Humidity: 0-95% non-condensing
• No external power required – fully passive

Why choose it

This balun transceiver simplifies your cabling infrastructure by converting unbalanced BNC video signals to balanced signals that travel over twisted-pair UTP. Because it is passive, there are no power supplies to mount or configure – just plug in your cameras and connect the RJ45 to your switch or receiver. The built-in surge protection helps safeguard your equipment from voltage spikes, and the compact ABS housing is durable enough for wall or rack mounting.

Ideal use cases

• Multi-camera surveillance in commercial buildings
• Parking lot and perimeter monitoring
• Warehouse and industrial site CCTV
• Retrofitting existing analog systems to HD-over-coax
• Long-distance video transmission over UTP

Good to know

The BCS-ZA4802 is a cost-effective alternative to running multiple coaxial cables. It works with standard Cat5e/6 cables and requires no configuration. Note that maximum transmission distances depend on the video format and cable quality; use solid copper UTP for best results.
