Altronix BNC24J 24-Inch Coaxial Jumper Cable
The Altronix BNC24J is a male-to-male BNC coaxial jumper cable engineered for mid-range component spacing in CCTV and video surveillance systems. This 24-inch cable bridges cameras, recorders, video distribution panels, and patchbays—anywhere a standardized coaxial connection is required. Coaxial construction preserves signal integrity over the cable run, minimizing impedance mismatch and reflections that degrade video quality on analog or hybrid surveillance networks.
Key Features
- 24-inch length: Strikes a balance between typical component spacing in equipment racks and field installations—long enough to route between mounted devices without slack, short enough to avoid excess coil that introduces capacitance and signal loss. Useful when camera leads don't reach the recorder directly and pre-made runs are impractical.
- Male-to-male BNC connectors: Standard coaxial video connectors found on legacy and modern CCTV equipment. Both ends terminate as male, allowing connection to female BNC jacks on cameras, recorders, video matrices, and test equipment.
- Coaxial construction: Maintains characteristic impedance (typically 75 ohms) required for analog video transmission. Shielding rejects electromagnetic interference common in security installations sharing conduit with power or network cabling.
- Lifetime Limited Warranty: Covers defects in material and workmanship for the life of the product—relevant for permanent rack or wall-mounted installations where replacement labor is high.
- Plug-and-play deployment: No configuration, termination, or special tools needed. Suitable for technicians who need to assemble custom patching solutions on-site or reconfigure systems during maintenance.
Integration & Compatibility
Compatible with any surveillance equipment equipped with female BNC jacks: analog cameras (NTSC/PAL), DVRs, hybrid recorders, video distribution amplifiers, coaxial video baluns, and test monitors. Commonly used in coaxial cable and connector assemblies for CCTV installations. Often paired with video surveillance recorders and analog camera systems where BNC termination is standard. Also suitable for patching between video distribution amplifiers or integrating legacy equipment into hybrid networks that still support coaxial video feeds.
Frequently Asked Questions
Q: What's the difference between a BNC24J and a longer cable like a BNC50J?
A: The BNC24J is 24 inches—ideal for short runs between adjacent rack-mounted components or between a nearby camera and wall-mounted recorder. Longer cables (36–50 inches) accommodate greater spacing. Shorter cables (12 inches or less) fit tightly packed equipment or patch panels. Choose based on your physical layout to avoid unnecessary coiling, which introduces signal distortion.
Q: Can I use this cable with HD-over-coax systems (HD-TVI, AHD, CVI)?
A: Yes. Although designed for analog video, the BNC24J's coaxial construction supports HD-over-coax formats (720p, 1080p) as long as the total run length and cable quality meet the system's distance specs. Check your recorder or camera documentation for maximum recommended cable length—24 inches is typically well within limits.
Q: Is the BNC24J shielded?
A: Coaxial cable inherently includes shielding (a conductive mesh or foil layer around the inner conductor). This shields against EMI from fluorescent lighting, RF sources, and AC power lines—a critical feature in installations where video cables run alongside electrical conduit.
Q: What's the impedance rating?
A: Standard coaxial video cables, including this jumper, are rated at 75 ohms. This matches the input impedance of CCTV equipment and ensures minimal signal reflection at connector junctions.
Q: Can I use this for analog audio, or only video?
A: This cable is optimized for video. While coaxial cable can carry audio, the BNC24J is specified and warranted for video surveillance applications. For audio interconnection, use audio-grade coaxial or balanced audio cables to avoid impedance mismatch and signal degradation.

The BNC24J is a straightforward, unglamorous cable that solves a specific problem: bridging video components separated by 24 inches without introducing signal degradation or clutter. In rack and wall-mounted CCTV installations, having the right cable length matters more than most technicians realize—undersized cables force tight coiling that adds capacitance; oversized cables invite sloppy routing that invites damage or EMI coupling. The BNC24J hits the middle ground.
Deployment Considerations:
- Coaxial shielding: The 75-ohm impedance and shielded construction are critical in electrically noisy environments—industrial warehouses, automotive facilities, or buildings with high RF interference. Unshielded or thin-gauge video cables in these settings will show ghosting, snow, or color shifts. The BNC24J's coaxial design mitigates this cost-effectively.
- Lifetime warranty covers material defects: This is relevant for permanent installations where a cable failure means tearing into walls, conduit, or cable trays. A manufacturing defect (corroded connector, open center conductor) discovered years later is covered—no cost to replace.
- Male-to-male connectors only: Watch for this—if your equipment uses female BNC connectors on both ends (unusual but possible in some matrices or test setups), you'll need an adapter or a male-to-female cable instead. The BNC24J only terminates male on both ends.
- Not suitable for long runs: At 24 inches, this cable is optimized for rack patching, short wall runs, or inter-cabinet bridging. If you need to run 50+ feet from a camera to a distant recorder, standard run coaxial cable (Belden 9223 or equivalent RG-6) is more economical and better for impedance matching over distance.
Deploy the BNC24J in hybrid surveillance systems where legacy analog CCTV equipment coexists with modern HD-over-coax recorders, or in retrofit projects where you're integrating new cameras into existing BNC-equipped infrastructure. It's not a performance upgrade—it's a reliability and installation-convenience asset, and that's exactly what you want from a cable.
