NVL201/300M Passive HD Video Balun Transceiver Pair | 300M Single Channel 📹🛡️

The NVL201/300M Passive HD Video Balun Pair is an essential transmission solution designed to convert 75 Ohm coaxial video signals into balanced signals for transmission over cost-effective twisted-pair (UTP Cat5e/Cat6) cables. Operating without external power, these single-channel transceivers support high-definition analog CCTV formats (AHD, HD-CVI, and HD-TVI) over long distances up to 300 meters, making CCTV camera installation smoother, cleaner, and more economical.

Key Product Features

• Universal Multi-Format HD Compatibility: Supports all major high-definition analog video standards including AHD, HD-CVI, and HD-TVI at 720P and 1080P resolutions.

• Long Transmission Range: Transmits real-time video signals up to 300 meters (300M) for CVI/AHD and 200 meters (200M) for TVI over unshielded twisted pair (UTP) Cat5e/Cat6 cable.

• Toolless Push-Terminal Design: Outfitted with quick-connect push-in terminal blocks marked clearly with positive (+) and negative (-) polarity icons for fast wire termination.

• 100% Passive Operation: Requires no external power supply, simplifying system design and lowering installation costs.

• Gold-Plated Male BNC Interface: Features a heavy-duty BNC-M connector with a flexible coaxial pigtail for easy connection to cameras or DVR channels in tight spaces.

• Built-In Protection & Noise Suppression: Features built-in surge/transient protection, ESD protection (IEC61000-4-2), and anti-interference capability (>60dB) for clean video transmission.

• Convenient 2-Piece Pack: Sold as a complete pair (transmitter and receiver units included in blister packaging) for a full single-camera link.

Top 3 Customer Questions & Concerns 🙋‍♂️

⚙️ Do I need to power these baluns with a 12V power supply?

No, these are passive transceivers, meaning they do not require any external electrical power to process and transfer the video signal.

🔌 Why use UTP network cables instead of traditional RG59 coaxial cables?

Using UTP (Cat5e/Cat6) cables is often significantly cheaper and easier to pull through conduits than heavy RG59 coaxial cables. Additionally, a single Cat6 cable contains 4 twisted pairs, allowing you to run up to 4 camera video channels through a single cable using 4 pairs of video baluns.

⚠️ Does polarity matter when stripping and inserting the network wires?

Yes! Always match the same wire color to the positive (+) terminal on both the camera end and the DVR end, and the second wire to the negative (-) terminal. Reversing polarity may result in a black-and-white or distorted video picture.
