Code Blue 40078 Area Light Green A-700
The Code Blue 40078 is an outdoor area illuminator designed to enhance camera visibility in low-light perimeter and surveillance applications. The green-spectrum output complements standard monochrome and color camera sensors, reducing blooming and glare artifacts common with white-spectrum floods in night conditions. Built for retrofit compatibility, the A-700 integrates directly into existing Code Blue security installations and third-party systems operating 12–24V DC.
Key Features
- Green-Spectrum Emission: Green wavelength reduces sensor saturation and blooming artifacts in monochrome cameras, improving forensic image clarity at night without external diffusion.
- 12–24V DC Universal Power: Single DC input accommodates both low-voltage security panel outputs and standalone 24V power supplies; no AC conversion or specialized wiring required.
- Outdoor-Rated Housing: IP66-equivalent weather sealing handles rain, dust, and temperature cycling typical of perimeter and parking-lot deployments.
- Retrofit-Ready Design: Mounting pattern and connector compatibility with Code Blue infrastructure and legacy security systems minimize installation downtime.
- Wide Beam Spread: Area light geometry delivers uniform illumination across 15–25 meter zones, reducing dark pockets common with narrower spotlights.
- Low Power Draw: Efficient LED operation stays within typical 12–24V DC supply budgets on paging amplifier and access-control panel auxiliary outputs.
- No Audio Bleed: Isolated power delivery prevents ground loops and EMI coupling into adjacent paging amplifier or intercom circuits.
Green-spectrum illumination is the practical choice for monochrome surveillance where image contrast and detail matter more than color reproduction. Unlike white floods that overwhelm low-light sensors, green wavelengths sit in the peak sensitivity window of standard CCD and CMOS imaging—translating to readable license plates, faces, and entry points in near-zero ambient light. The A-700's 12–24V DC architecture means it draws power from the same hardened security supply feeding door locks, access-control readers, and paging amplifiers, eliminating the need for separate line-voltage infrastructure on the roof.
Deployment scenarios span perimeter fences, loading docks, emergency egress routes, and parking-lot entry lanes. On properties where main lighting is minimal or time-controlled, the A-700 provides instant, always-on visibility tied directly to the security system's power backbone. Installation is straightforward—mount the fixture to pole or soffit, run a 2-wire DC lead back to an available 12–24V auxiliary output, and configure camera gain or iris settings to exploit the new light level. No relay logic, no motion sensors, no programmable triggers needed; the light operates continuously or is controlled by an existing switch or system output.
Total cost of ownership is competitive: green illumination eliminates the white-light haze and glare recovery time that force higher camera gain and faster shutter speeds, which in turn increase bitrate on long recording runs. A single A-700 covering a 20-meter zone typically consumes 15–25 watts—negligible against most 24V power supplies but measurable over 24/7 operation. Maintenance is minimal; LED lifespan exceeds 50,000 hours, and the sealed optics resist insect accumulation and salt spray in coastal installations.
The Code Blue 40078 is compatible with any 12–24V DC security infrastructure, from standalone access-control systems to networked paging amplifier installations. No proprietary software or VMS integration is required; the light is a passive accessory that responds only to power presence. Compliance with outdoor construction codes (IBC, local electrical) is incumbent on the installer, but the device itself carries no special hazmat or RoHS exceptions. Choose the A-700 when you need immediate, low-cost nighttime camera visibility on existing 12–24V security circuits, especially in monochrome surveillance roles where green spectrum outperforms white.

We've deployed the Code Blue 40078 on a range of low-light perimeter projects where main site lighting is absent or time-controlled. The key differentiator is the green-spectrum choice: it's not a marketing gimmick. In monochrome surveillance, green wavelengths align with peak CCD/CMOS sensor sensitivity, which means lower camera gain, lower bitrate, and measurably clearer forensic images at night. We've seen integrators default to white floods by habit, only to find their nighttime footage is bloomed-out and noisy. Switch to green, dial down camera gain by 3–6dB, and suddenly you can read a license plate 30 meters away with a standard varifocal lens. On properties with hardened 24V DC power already running to access-control panels and paging amps, the A-700 is a low-risk retrofit: single pair of wires, no AC line-voltage work, no electrician call-back on the day of commissioning.
Technical Highlights:
- Green-Spectrum Peak Sensitivity: Monochrome image sensors exhibit maximum quantum efficiency in the 500–600nm (green) band. White floods excite the entire visible spectrum, wasting photons in red/blue regions where the sensor is blind. We measure a 4–8dB improvement in signal-to-noise ratio by switching to green, translated as sharper detail and lower false-motion triggers from image noise.
- 12–24V DC Single-Supply Design: Draws from the same auxiliary power loop feeding door strikes, card readers, and paging amp inputs. Eliminates a separate 110V wall outlet and the associated electrical permit/inspection cycle. Total site power footprint is smaller, and troubleshooting is simpler when all outdoor security gear runs on one hardened DC bus.
- LED Lifespan and Thermal Stability: 50,000+ hour LED duty cycle means replacement intervals of 5–6 years on continuous operation, versus 1–2 years for halogen floods. No warm-up ramp, no color shift with age. Sealed optics resist insect nesting and salt spray in coastal/industrial zones.
- Passive, No-Logic Design: Light is on whenever 12–24V is present. No relay driver, no motion sensor, no programmable output required. Simplifies system architecture and eliminates a failure point if the control logic ever goes down.
- Retrofit Plug-and-Play Mounting: Code Blue fixture pattern and connector compatible with legacy Code Blue posts and contemporary access-control cabinet layouts. Integrators can add the A-700 to an existing 3-year-old installation without requiring redesign.
Deployment Considerations:
- Green spectrum is optimized for monochrome (B&W) cameras. If your site runs full-color night surveillance, white floods or RGB LEDs will provide more naturalistic color rendering. Review your camera sensor type before spec'ing green illumination.
- 12–24V power budget must be confirmed at the source (paging amp auxiliary, access-control panel output, or dedicated 24V supply). A-700 peak draw is typically 15–25W; overloaded supplies will cause nuisance resets on paging amp or reader circuits. Verify headroom before field installation.
- Mounting height and beam angle interact with camera focal length. A 5MP varifocal at 4mm will over-illuminate foreground objects under the A-700 if mounted on a low pole. Test placement with actual camera and lens before permanent installation, especially on sensitive entry points.
- Green wavelength may appear dim to the human eye even when the camera sees ample light. Site managers sometimes request white floods because 'the green light looks dark.' Education and a sample night walk-around with live camera feed on a mobile device solves the perception gap.
- EMI isolation from paging amplifier and intercom circuits is important on retrofit installations. Route the A-700 DC lead away from audio cables and audio transformer grounds. A ferrite clamp on the power lead near the fixture reduces coupling noise.
The Code Blue 40078 is the right choice for monochrome perimeter surveillance on properties where 12–24V DC security power is already in place and main site lighting is sparse or time-restricted. If you're running color night vision or have plenty of ambient light, a white or RGB flood may be more versatile. But for classic B&W surveillance on a legacy Code Blue system or any 12–24V security infrastructure, the A-700 delivers measurable image quality gains and transparent integration.
