UltraPoE CT-VBHD-4H 4-Channel Passive HD CCTV Video Balun Hub

UltraPoE CT-VBHD-4H is a compact four-channel passive HD CCTV video balun hub for carrying compatible AHD, HD-TVI, and HD-CVI camera signals over CAT5, CAT5e, or CAT6 twisted-pair cable. It consolidates four BNC video channels into one RJ45 or one 8-pin terminal connection and requires no external power.

Key Features

• Four passive CCTV video channels in one compact metal enclosure
• No external power supply required
• Compatible with AHD, HD-TVI, and HD-CVI signals
• Four numbered BNC female video connectors
• Choose RJ45 or 8-pin terminal-block connection for UTP cabling
• Bidirectional design for use at either end of the video link
• Real-time, non-network video transmission
• Surge, ESD, and interference protection as listed

Listed Passive-to-Passive Distances

• HD-CVI 720p: up to 400 m
• HD-CVI 1080p: up to 250 m
• HD-TVI 720p / 1080p: up to 250 m
• AHD 720p: up to 350 m
• AHD 1080p: up to 200 m

Maximum distance varies with signal format, cable quality, connectors, grounding, and installation conditions. The legacy specification also lists operation up to 600 m when paired with compatible active equipment.

Installation Notes

Use one compatible balun hub at each end of a dedicated four-pair UTP cable. Connect channels 1–4 consistently at both ends. The RJ45 and terminal block are alternative wiring methods for the same four-channel link; do not connect the RJ45 port to an Ethernet switch or IP network.

Frequently Asked Questions

Does the CT-VBHD-4H require power?

No. It is a passive, non-amplified video transceiver.

How many CCTV channels does it carry?

It carries four compatible video channels through one CAT5, CAT5e, or CAT6 cable link.

Can I use both the RJ45 and terminal block at the same time?

They are alternative UTP connection methods. Choose the connection that matches the installation.

Is the RJ45 port an Ethernet network port?

No. It carries dedicated CCTV balun signals and must not be connected to a network switch.
