Nitek VB31AT HD Video Balun Combiner, Vpp Composite Video Monochrome/Color Input, Balanced Low Voltage Current Loop Output, RJ45 Jack, 1" Width 2" Depth 0.9" Height

For security integrators and facilities managers who need reliable video plus power over a single cable, the Nitek VB31AT video balun delivers a simple, cost-effective solution. This video balun sends composite video over one twisted-pair and routes camera power over two additional pairs, letting you power and monitor CCTV cameras using a single Cat5/Cat6 run. The VB31AT uses a mini-coax pigtail with a male BNC for easy camera connection and an RJ45 jack wired to 568B standards so spare network cables can be used on-site.

Designed for surveillance, monitoring and security installations, the VB31AT provides balanced low-voltage current loop output, excellent immunity to noise and built-in surge suppression to protect equipment and maintain image integrity. Its compact 1" x 2" x 0.9" footprint simplifies mounting inside junction boxes and enclosures. RoHS-compliant and backed by a limited lifetime warranty, the VB31AT reduces material costs, speeds deployment and improves system reliability. Ideal for CCTV, retail, commercial and industrial monitoring projects—specify the Nitek VB31AT to streamline installations and improve uptime.
