Hanwha HNW-SS-806 Line Level Wall Microphone

Hanwha HNW-SS-806 Line Level Wall Microphone

Overview

The Hanwha HNW-SS-806 is a flush-mount, line-level microphone purpose-built for high-security environments where tampering risk and ligature vectors demand purpose-engineered audio capture. Constructed from 12-gauge stainless steel with anti-ligature design and zero protruding attachment points, the HNW-SS-806 is specified for law enforcement interview rooms, correctional facilities, detention intake areas, common spaces, and visitation zones. The omni-directional pickup pattern delivers consistent audio capture across a roughly 12-foot radius — meaning conversations or disturbances anywhere in the monitored space get picked up equally, regardless of microphone location on the wall or ceiling.

Key Features

• Anti-Ligature Stainless Steel Construction (12-Gauge): Eliminates tampering vectors critical in correctional and detention environments. No protruding components means nothing to cut, bend, or weaponize — a material safety requirement where officer and inmate safety depends on removing ligature points entirely.
• Omni-Directional Pickup (~12-Foot Radius Coverage): Audio capture extends roughly 12 feet in all directions without directional dead zones. You don't need to angle the microphone or debate which wall to mount it on — sound gets picked up consistently across the space, reducing the need for multiple mics in small rooms.
• Flush-Mount Design for Wall or Ceiling Installation: Sits completely flush with the mounting surface, leaving no protrusions that could be gripped, struck, or used as a ligature point. Mounts cleanly into drywall, tile, or other surfaces without a separate housing or bracket, simplifying installation and maintenance.
• Built-In Baffling for Diaphragm Protection: Internal acoustic design protects the microphone element from physical strikes and dust ingress — a practical safeguard in high-stress environments where equipment receives rough handling.
• Line-Level Output (2.2kΩ Impedance): Integrates directly into standard microphone input ports on IP cameras, network video recorders, and video management systems without requiring external preamps or level converters. The 2.2kΩ impedance is compatible with professional audio inputs across the IP security ecosystem, reducing configuration complexity.
• 60dB Signal-to-Noise Ratio: Clean audio capture with background noise suppressed by 60 decibels, ensuring interview recordings, incident documentation, and surveillance audio remain intelligible even in moderately noisy areas like intake processing zones or multi-inmate common spaces.
• Frequency Response 30Hz–15kHz: Covers the human voice intelligibility range (300Hz–3kHz) plus environmental audio below and above. This breadth means you capture both spoken words and relevant situational audio — alarms, door slams, physical altercations — without filtering.
• Low Power Draw (12VDC at 20mA): Draws approximately 240 milliwatts, so it won't strain facility power infrastructure or require heavy-gauge cabling runs. Power can be distributed via standard 12V supplies shared with other security devices.
• Wide Operating Temperature Range (−25°C to 70°C / −13°F to 158°F): Performs reliably in unheated storage areas, outdoor vestibules, loading docks, or warm server closets without thermal shutdown or recalibration. No seasonal performance degradation across typical facility climates.
• Made in the USA: Domestic manufacturing supports supply chain transparency and compliance certifications common in government and law enforcement procurement, particularly for facilities requiring NDAA Section 889 oversight.

Integration and Compatibility

The HNW-SS-806 connects to any IP camera, network video recorder, or video management system with a standard microphone input jack. Run 18/2 or 22/2 AWG shielded cable from the microphone location to your recorder or camera input. Line-level output means no additional amplification, preamplifier, or audio interface is required — plug the cable into the mic-in port and configure audio recording in your VMS. If integrating with Hanwha IP cameras that include audio input capability, the HNW-SS-806 pairs directly without adapter or level-matching hardware. For facilities deploying distributed surveillance systems with multiple microphones, the low power draw simplifies 12V distribution and reduces cabling strain.

When to Choose a Different Model

If your deployment requires higher signal-to-noise performance (SNR above 60dB) in very high-ambient-noise environments, or if you need bullet-style or dome-mounted form factors instead of flush-mount wall installation, consult the broader Hanwha microphone line for alternatives. If you need two-way (speaker + microphone) capability in a single unit, the HNW-SS-806 is audio-input-only and won't fulfill that requirement. For outdoor exposed installations where stainless steel alone is insufficient and you need IP67 submersion protection, this model is indoor/covered-space rated and would not be appropriate.

Typical Deployments

Law enforcement interview and interrogation rooms benefit from the anti-ligature design and omni-directional pickup — interrogators and interviewees move around the space, and the HNW-SS-806 captures dialogue consistently from any location. Correctional facilities use this microphone in common areas, visitation zones, and intake processing to document interactions and flag incidents in real time. Detention facilities deploy it in holding cells and transport areas where robust, tamper-resistant audio capture is a custody safety requirement. Psychiatric and mental-health crisis units benefit from the ligature-resistant design and the ability to document verbal threats or behavioral incidents across the room without directional bias.

Installation Considerations

Mount the HNW-SS-806 at roughly the center of the space you're monitoring, or at the most acoustically neutral location (away from air returns, HVAC noise, or machinery). Since pickup is omni-directional with a ~12-foot radius, a single microphone typically covers a small interview room, cell block common area, or intake station. Ensure 12VDC power is available near the installation point, or plan a separate 12V supply run if the microphone location is remote from your recorder or camera. Test audio levels and background noise during commissioning — 60dB SNR is solid, but if ambient noise is very high, you may need to position the microphone closer to the source of interest (spoken word) or consider a second microphone in larger spaces.

Frequently Asked Questions

Q: Can the HNW-SS-806 be mounted on a ceiling instead of a wall?

A: Yes. The omni-directional pickup pattern and flush-mount design work equally well on ceiling or wall surfaces. Ceiling mounting can improve coverage in rooms with furniture or obstacles that might create acoustic shadows on walls.

Q: Is the HNW-SS-806 compatible with all video management systems?

A: The microphone outputs standard line-level audio and connects via shielded cable to any recorder or VMS with a microphone input jack. ONVIF-compliant systems and IP cameras with audio inputs will integrate without issue. Verify your recorder or camera has a free audio input port before ordering.

Q: What cable type and run length is recommended?

A: Use 18/2 or 22/2 AWG shielded microphone cable. Typical runs up to 50 feet present no signal degradation. For runs beyond 100 feet, consider upgrading to higher-gauge shielding or using a short XLR adapter near the microphone to boost signal integrity.

Q: Does the HNW-SS-806 require external power amplification?

A: No. The microphone delivers line-level output (2.2kΩ impedance) directly compatible with microphone input ports on IP cameras and recorders. No preamplifier, audio interface, or mixer is needed.

Q: Is the stainless steel housing guaranteed ligature-proof?

A: The 12-gauge stainless steel construction eliminates protruding attachment points and sharp edges that could be exploited for ligature risk. However, any installation should be reviewed by facility safety and custody staff before deployment. The microphone is engineered to remove obvious vectors — it is not a substitute for broader environmental safety audits.

Q: What is the warranty coverage on the HNW-SS-806?

A: Refer to the manufacturer's warranty documentation or contact an authorized dealer for current warranty terms and any coverage specifics related to your purchase.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The HNW-SS-806 is engineered for a specific deployment class: high-custody environments where microphone tampering or ligature risk is a documented safety concern. Unlike general-purpose line microphones, this unit's 12-gauge stainless steel construction and flush-mount form factor eliminate the obvious attack vectors that make standard microphones problematic in correctional and detention settings. The 60dB signal-to-noise ratio and omni-directional ~12-foot pickup radius mean you're not sacrificing audio quality for safety — you're getting solid intelligibility across interview rooms, intake areas, and common spaces without directional nulls.

Technical Highlights:

• Anti-Ligature Design (12-Gauge Stainless Steel): Zero protruding components, no screws, no attachment points. In a custody environment, this eliminates material that could be used for self-harm or weapon fabrication — a real security requirement that standard microphones don't address.
• Omni-Directional Pickup with ~12-Foot Radius: You're not limited to a forward-facing coverage zone. A person can move anywhere within the room and remain clearly audible. For interview rooms where the suspect or witness moves around, or intake areas with unpredictable positioning, this is a practical advantage over cardioid or hyper-cardioid mics.
• Low Power Draw (12VDC at 20mA / ~240mW): Minimal electrical load means power distribution is straightforward — no heavy-gauge cabling, no strain on facility electrical infrastructure. Standard 12V supplies (common in security installs) can power multiple units without redesign.
• Line-Level Output (2.2kΩ Impedance) Direct to Recorder/VMS: No preamplifier needed. Plug into any camera or NVR with a mic-in jack and configure recording in software. This reduces BOM cost, complexity, and potential failure points in the audio chain.

Deployment Considerations:

• Omni-directional pickup is an asset in single-microphone deployments but a liability if you're trying to isolate one speaker from background chatter. In high-traffic areas or multi-occupancy spaces, consider whether a directional microphone might be more appropriate.
• The 60dB SNR is solid but not exceptional — if your facility has very high ambient noise (HVAC, machinery, traffic), you may need to position the microphone closer to the source of interest or deploy multiple units to avoid intelligibility loss.
• Installation height and location matter. Mounting near air vents, HVAC returns, or machinery will degrade signal-to-noise performance. Center placement or acoustically neutral wall positions yield best results during commissioning.

The HNW-SS-806 is the right choice for law enforcement, correctional, and detention facilities where anti-ligature audio capture is a facility safety requirement. If you're deploying in a standard commercial office, warehouse, or retail security system, a cost-effective omni-directional microphone without the hardened construction will work fine and cost less. But in custody environments, the ligature-resistant design and robust stainless construction are non-negotiable — the HNW-SS-806 is the product that delivers that without compromise.
