Technical Specifications

Installation & Compatibility

Camera and Monitor Compatibility The HDC20M-4P extension cable is compatible with backup cameras, side cameras, and monitors using industry-standard universal 4-pin pinout configuration. Compatible equipment includes most aftermarket vehicle cameras and monitors from major manufacturers utilizing standard pin assignments for power, ground, and video signals. Verify equipment uses universal standard 4-pin configuration rather than proprietary pinouts such as AXIS-specific or manufacturer-specific configurations which would require appropriate converter adapters. Check equipment specifications or contact manufacturers to confirm pinout standard before purchasing extension cable.

Cable Routing Planning Before installation, plan cable routing path from camera location to monitor considering distance requirements, obstacles, and protection from damage. Measure actual cable path length accounting for vertical runs, horizontal spans, and routing around vehicle structures ensuring 20-metre cable provides adequate length with minimal excess. Identify cable entry points through vehicle body panels, floor, or ceiling requiring grommets or protective bushings preventing chafing against sharp metal edges. The 20-metre length accommodates complex routing paths in extra-large vehicles, articulated combinations, or installations requiring cable runs through multiple compartments, chassis sections, or along extended vehicle frames.

Installation Process Connect 4-pin male end of extension cable to female connector on camera output, monitor input, or existing extension cable. Connect 4-pin female end to male connector from camera cable, monitor input cable, or additional extension cable. Ensure threaded coupling nuts engage fully and tighten hand-tight creating weatherproof seal and secure mechanical connection. Route cable along vehicle frame rails, body panels, or existing wiring harnesses avoiding hot surfaces near exhaust systems, moving components such as steering linkages, and areas where cable could be pinched or damaged.

Cable Protection and Securing Secure extension cable every 300-500mm using cable ties, cable clips, or cable looms preventing excessive movement that could cause vibration wear or stress on connectors. Use spiral wrap, split loom tubing, or conduit in areas exposed to abrasion, UV light, or physical damage such as undercarriage routing or exposed frame rail mounting. Install grommets where cable passes through body panels preventing chafing against sharp metal edges that could damage cable jacket and cause short circuits or signal loss. The extended 20-metre length requires meticulous securing along entire cable run preventing sagging sections that could snag on obstacles, drag on road surfaces, or create trip hazards in walkways.

Connection Point Protection Position connectors in protected locations away from direct water spray, road debris, and physical impact. While connectors provide IP67 weatherproof rating when properly connected, mounting in sheltered locations extends service life and prevents damage from external forces. Use connector boots or heat shrink tubing over connection points providing additional environmental protection and strain relief. For 20-metre runs, consider positioning connectors in accessible locations enabling future disconnection for troubleshooting without requiring complete cable removal.

System Testing After Installation After completing installation, power vehicle electrical system and monitor verifying video display appears clearly without distortion, interference, or color abnormalities. Test video quality at various engine speeds confirming shielding prevents alternator noise interference. Check connections under vehicle vibration by operating vehicle over rough surfaces while observing monitor for intermittent signal loss indicating loose connections requiring tightening. The 20-metre cable length makes thorough testing critical confirming signal quality remains acceptable over maximum extended distance. Test in both daylight and night conditions verifying image clarity under various lighting scenarios.

Signal Quality Considerations The 20-metre length represents maximum practical distance for passive extension cables. While high-grade low-loss construction maintains signal quality, installations at this length should carefully evaluate video quality during testing. Factors affecting signal quality include cable routing near electrical interference sources, number of connection points in series, total system cable length including factory cables, camera output signal strength, and monitor input sensitivity. If experiencing marginal signal quality at 20-metre length, consider signal amplifiers or active extension cables maintaining video quality over extended distances. Avoid exceeding 20 metres total cable length without signal amplification.

Frequently Asked Questions

Is 20 metres the maximum length for camera extension cables?

The HDC20M-4P 20-metre length represents maximum practical distance for passive extension cables maintaining acceptable video quality without signal amplification. While cable physical length could theoretically exceed 20 metres, signal loss, voltage drop, and interference susceptibility increase with distance causing degraded video quality. Installations requiring runs exceeding 20 metres should utilize video signal amplifiers or active extension cables boosting signal strength maintaining quality over extended distances. Total system cable length including factory camera cables and extension cables approaching or exceeding 25 metres typically requires amplification. For maximum distance installations, test video quality thoroughly during installation confirming acceptable image clarity before permanent installation.

Can I use this cable with AXIS proprietary pinout equipment?

No, the HDC20M-4P uses industry-standard universal 4-pin pinout configuration incompatible with AXIS proprietary pinout equipment. AXIS brand cameras and monitors using AXIS-specific pin assignments require AXIS-compatible extension cables or HDC/AX-F and HDC/AX-M converters bridging compatibility between AXIS and universal equipment. Using this universal extension cable with AXIS equipment results in no video display or potential equipment damage due to incorrect power and signal pin connections. Verify equipment pinout standard before purchasing extension cable ensuring compatibility. For AXIS equipment, select AXIS-specific extension cables or use appropriate converters with this universal extension cable.

Will video quality be acceptable over 20 metres?

The HDC20M-4P high-grade low-loss construction maintains good video quality over full 20-metre length under optimal conditions. However, the 20-metre distance approaches maximum practical cable length where signal degradation becomes more noticeable compared to shorter cables. Video quality depends on multiple factors including camera output signal strength, monitor input sensitivity, electromagnetic interference environment, connection quality, and total system cable length. After installation, evaluate video quality by observing monitor display for clear detailed image with accurate colors and no interference. If experiencing reduced brightness, color desaturation, visible interference, or reduced detail clarity, verify all connections tight, inspect cable routing avoiding electromagnetic interference sources, and consider signal amplifier for marginal installations. Most quality camera systems perform adequately with 20-metre extensions, but this length represents upper limit before amplification typically becomes necessary.
