Key Features of Our 18/4 Shielded Alarm Security Cable 1000ft

• Aluminum Foil Shield with Drain Wire — Complete EMI Suppression: The aluminum foil shield on this 18/4 shielded alarm security cable 1000ft encloses all four conductors with a bare copper drain wire for single-point grounding at the security panel or head-end equipment. This shield provides 100% EMI and RFI coverage against adjacent cable bundles, fluorescent ballasts, HVAC equipment, and other interference sources commonly found in commercial security installations. Moreover, proper shield grounding eliminates ground loops that would otherwise introduce noise on motion detector circuits, keypad signal lines, and CCTV video feeds.
• 18AWG Stranded Copper Conductors: Four 18AWG stranded copper conductors deliver reliable signal and power transmission with excellent flexibility for routing through walls, ceiling spaces, conduit, and cabinet interiors. Stranded construction allows the cable to bend around corners and navigate tight routing paths without conductor fatigue or fracture — a critical advantage on high-device-count security rough-in projects with multiple bends per run. Additionally, stranded wire terminates cleanly under screw terminals and connector blocks at alarm panels, cameras, and keypads.
• 4-Conductor Configuration for Multi-Circuit Security Runs: The four-conductor format is the defining advantage of this 18/4 shielded alarm security cable 1000ft over 2-conductor alternatives. A single cable run can simultaneously carry both a signal pair and a DC power pair to a CCTV camera, deliver the arm, disarm, tamper, and common conductors to a zone expander, or provide the four conductors required for a two-way intercom or access control reader with power. As a result, the 4-conductor format reduces total cable runs and conduit fill on every multi-zone security project.
• 1000ft Pull Box — Maximum Coverage Per Roll: The 1000ft pull box provides double the cable of a standard 500ft box, making it the preferred format for large commercial rough-in jobs, multi-floor security deployments, and warehouse or campus security installations. Furthermore, the 1000ft format reduces mid-run splices — each splice is a potential resistance variation and failure point in a security circuit. The pull box design delivers tangle-free payout throughout the entire 1000-foot roll.
• Durable White PVC Jacket: The white PVC outer jacket resists wear, moisture, and environmental stress in both indoor and protected outdoor installations. Furthermore, the white jacket is the industry-standard color for security system wiring in residential and light commercial environments, blending with white wall surfaces, junction boxes, and cable management systems for a professional, unobtrusive installation.
• Compatible with CCTV, Alarm Panels, and Access Control: This 18/4 shielded alarm security cable 1000ft is confirmed compatible with CCTV security camera systems, burglar alarm panels, access control systems, intercom networks, and monitoring devices. Consequently, a single cable SKU serves every major system type on a mixed-technology security project, simplifying procurement and reducing the number of cable reels on the job site.
• Flexible for Indoor and Protected Outdoor Use: The stranded conductor construction and PVC jacket make this cable suitable for installation in finished wall cavities, surface-mount raceway, conduit, and protected outdoor runs where the cable is not exposed to direct UV or direct burial conditions. As a result, it handles the full range of security cabling environments encountered in commercial and residential projects.
• Cost-Effective for High-Device-Count Projects: At 1000ft per pull box, this 18/4 shielded alarm security cable 1000ft provides the lowest per-foot installed cost in the 52Networks alarm security cable range. Therefore, security contractors managing multi-zone, high-device-count projects consistently select the 1000ft format to minimize material cost and maximize project margin.

Why Choose This 18/4 Shielded Alarm Security Cable 1000ft for Your Project?

The shielded 4-conductor format of this 18/4 shielded alarm security cable 1000ft addresses the two most common technical challenges in commercial security rough-in: insufficient conductors per run and EMI-induced nuisance faults. In dense commercial environments where security, AV, lighting control, and data cabling share the same wall and ceiling pathways, unshielded 2-conductor cable can develop induced interference on motion sensor circuits and CCTV feeds — problems that appear only after occupancy and are expensive to diagnose and correct. The aluminum foil shield eliminates this risk from installation day one. Moreover, the 4-conductor format ensures that every device connection in the system has the conductor capacity to accommodate both signal and power, eliminating the most common cause of post-installation service calls: discovering a device that requires more conductors than the installed cable provides. For security installations in plenum ceiling spaces where the jacket must carry a CL3P or CMP fire rating, upgrade to our 18/4 CL3P Plenum Shielded Cable 500ft (DoFollow).

The 1000ft format is a direct economic and operational advantage on large commercial security projects. At 1000 feet per roll, a single pull box can cover the entire first-floor security rough-in of a mid-size commercial building — keypads, motion sensors, door contacts, and camera power feeds — without a single cable change-out mid-project. Furthermore, the continuous 1000ft run eliminates the splice points that a 500ft-then-500ft approach would introduce, keeping circuit resistance consistent and reducing the number of junction boxes required for compliance. In other words, the 1000ft pull box is the professional’s choice for projects where installation efficiency and system reliability both matter. Additionally, the ANSI/TIA-570-D standard for residential and light commercial cabling (nofollow) recommends minimizing cable splices on security and alarm circuits to maintain signal integrity — a recommendation this 1000ft format inherently satisfies. For the 2-conductor variant at the same 1000ft length, see our 18AWG Shielded Alarm Security Cable 2-Conductor 1000ft White (DoFollow).

The white jacket on this 18/4 shielded alarm security cable 1000ft is the standard color for residential and light commercial security system wiring throughout the US market. White cable disappears visually against white drywall, white trim, and white surface-mount raceways, giving finished security installations a professional, low-profile appearance that building owners and facility managers expect. Furthermore, white jacket color is the convention used by the majority of security panel manufacturers in their installation documentation when specifying zone wiring, keypad wiring, and power supply wiring.

Frequently Asked Questions

Q: What is the difference between this non-plenum 18/4 shielded security cable and the plenum-rated 18/4 CL3P version?

The primary difference is the jacket fire rating and the installation environment each version is legal for. This 18/4 shielded alarm security cable 1000ft has a standard PVC jacket rated for in-wall installation in non-plenum spaces — specifically wall cavities, conduit, surface raceway, and cable tray in areas of a building that are not used for air circulation. The 18/4 CL3P plenum version carries a higher fire rating that permits installation in air-handling ceiling cavities and HVAC ducts where the NEC requires low-smoke, flame-retardant cable. If your security circuit runs entirely through wall cavities and standard conduit without passing through a plenum ceiling space, this non-plenum cable is the appropriate and more economical specification. However, if any portion of the run passes through an air-handling plenum ceiling, the entire run must use plenum-rated cable per NEC Article 725. Therefore, always verify the pathway for each security circuit with your local AHJ before specifying the jacket rating.

Q: Why choose the 1000ft pull box format over two 500ft boxes for a large commercial security project?

The 1000ft pull box format of this 18/4 shielded alarm security cable 1000ft provides three specific advantages over combining two 500ft boxes. First, a continuous 1000ft run eliminates any mid-run splices, keeping circuit resistance consistent from panel to device and removing potential open-circuit failure points that splices can develop over time. Second, the 1000ft format reduces the number of physical cable change-outs during installation, cutting the time installers spend stopping to swap boxes mid-run. Third, the 1000ft format typically delivers a lower per-foot material cost than two 500ft boxes of equivalent cable, directly improving project margin on high-cable-count security deployments. Furthermore, fewer rolls means less waste from partial boxes, which is particularly valuable on projects where cable lengths are unpredictable until actual device placement is finalized. Consequently, experienced security contractors standardize on 1000ft pull boxes for commercial projects whenever the cable rating and jacket type permit.

Q: Can this 18/4 shielded alarm security cable be used for both CCTV camera power and video signal on the same run?

Yes — the 4-conductor format of this 18/4 shielded alarm security cable 1000ft is specifically suited for CCTV camera installations where both a video signal pair and a DC power pair must be delivered in the same cable run. For analog HD cameras using coaxial-free technologies such as HDCVI, HDTVI, AHD, or IP-over-UTP, four conductors provide the complete signal and power circuit in a single pull — eliminating the need for a separate power cable to each camera location. The aluminum foil shield suppresses the EMI that causes noise, banding, and color distortion on video feeds running near lighting circuits, power distribution wiring, and other low-voltage cable bundles in the same conduit or wall cavity. Additionally, the 18AWG conductors provide sufficient current capacity for 12VDC camera power circuits on typical commercial camera run lengths. As a result, this cable is the practical single-cable solution for CCTV rough-in on projects where a separate RG59 coaxial cable is not the preferred architecture.
