Hikvision DS-QAZ1120G1R-B Network Cabinet Speaker with PoE Audio, 20W Rated Power, 5.25″ Driver, 103dB Max SPL

Model: DS-QAZ1120G1R-B

Who This Is For

For integrators and facilities managers who need a clean, network-driven public address solution without running separate power cabling to every speaker position. The Hikvision DS-QAZ1120G1R-B is a PoE-powered IP network cabinet speaker designed for structured deployments where audio is managed centrally over an existing IP network. With a 20W rated output, a 5.25-inch driver, and a 103dB maximum SPL, it suits spaces that demand genuine volume and intelligibility - think commercial lobbies, warehouses, school corridors, retail floors, and large open-plan offices. The cabinet enclosure makes it a practical fit for wall-mount or fixed-surface installations where a neat, self-contained form factor matters. If your site already runs Cat cable to speaker positions and you want to consolidate audio into the same IP infrastructure as your security system, this is the product category that makes that possible.

What This Speaker Actually Does

Who Buys This Model

• Commercial Integrators: Specifying IP audio zones in office fitouts or retail chains where Cat cabling is already run and a central audio server manages all speaker endpoints.
• Warehouse and Industrial Facilities Managers: Needing a speaker that delivers 103dB SPL to cut through machinery and ambient noise for safety announcements or shift alerts.
• School and Education IT Teams: Deploying PoE audio across corridors and classrooms where a single structured cabling run simplifies both installation and ongoing management.
• Security System Integrators: Adding IP audio to an existing Hikvision network infrastructure so that camera-triggered or alarm-triggered announcements can be broadcast from specific speaker zones.
• Property Developers and Building Services Contractors: Specifying a standardised, PoE-based speaker for multi-tenancy or mixed-use buildings where a traditional 100V line PA system would require a dedicated amplifier room.

Honest Assessment

The DS-QAZ1120G1R-B does a specific job well: it delivers 20W of network-addressable audio from a single Cat cable, which eliminates the cost and complexity of 100V line transformer wiring or running separate 240V power to speaker positions. The 103dB maximum SPL and 5.25-inch driver make it genuinely useful in commercial and light-industrial environments, not just background-music applications. The cabinet format is straightforward to surface-mount where ceiling tiles are absent or inaccessible. Where this speaker will not serve you: if your site requires weatherproof outdoor audio, a humidity-rated or IP65-rated speaker variant would be a more appropriate choice. If you need very wide-area coverage from a single point, a higher-wattage horn or column speaker would project further. For installations that must comply with AS 7240 life safety or emergency warning system standards, a dedicated EWIS-approved device is required. Available through Security Australia, this speaker suits structured IP audio deployments rather than standalone or analogue-first setups.

Before You Buy

Quick Fit Check

• Good match if: Your site already has Cat cabling run to speaker positions and you want to eliminate 100V line transformers and centralise audio management over IP.
• Good match if: You need a speaker that produces 103dB SPL for announcements in a noisy warehouse, corridor, or open commercial space where ambient noise levels are high.
• You may need a different model if: Your installation is outdoors or in a high-humidity environment - a weatherproof IP-rated speaker enclosure would be the more appropriate product type for those conditions.

Real-World Scenarios

How It Compares

• Choose this if: Your site has Cat cabling infrastructure and you want PoE-powered, network-managed audio without 100V line transformers or separate power circuits at each speaker position.
• You may need a different model if: Your installation is outdoors or in a wet area - a weatherproof IP-rated outdoor speaker enclosure is the appropriate product type for exposed or high-humidity environments.
• Pairs well with: A PoE+ managed network switch with sufficient per-port power budget, a compatible IP audio server or VMS with audio output support, and structured Cat6 cabling throughout the installation.

Common Questions

1. Does this speaker need a separate power supply at the installation point?

   No. The DS-QAZ1120G1R-B is powered entirely over the Ethernet cable via PoE, so no 240V outlet or external power adapter is required at the speaker location. A single Cat cable run from a PoE-capable switch carries both the network audio stream and power to the unit - simplifying installation in walls, ceilings, and corridors where running additional power cabling would be costly.

2. Will this speaker work with a standard PoE switch, or does it require PoE+?

   This depends on operating power draw. Standard IEEE 802.3af PoE delivers up to 15.4W at the port, while the rated output of this speaker is 20W. If the speaker requires full rated power to operate, a PoE+ (IEEE 802.3at) switch port delivering up to 30W would be needed. Confirm your switch's per-port power specification before installation and check total switch power budget when deploying multiple units across the same switch.

3. What is the maximum SPL, and will it be loud enough for a noisy warehouse?

   The DS-QAZ1120G1R-B is rated at 103dB maximum SPL. In a typical warehouse environment with ambient noise levels of 70-85dB, a 103dB speaker at close-to-moderate distances will produce clearly audible announcements with meaningful headroom above background noise. For very large open sheds or areas with particularly high ambient noise, consider the speaker coverage radius and whether multiple units are required to maintain intelligibility across the whole zone.

4. Does this speaker work with third-party VMS or audio platforms, or only Hikvision systems?

   It is designed as a Hikvision IP audio device and will integrate natively with compatible Hikvision network audio management platforms. Third-party VMS compatibility depends entirely on whether that platform supports Hikvision IP audio endpoints - many generic VMS platforms do not include IP audio speaker management. Confirm with your VMS vendor or the team at Security Australia before specifying this unit for a mixed-brand environment.

5. Can this speaker be used outdoors?

   No - not without additional protection. The DS-QAZ1120G1R-B is a cabinet speaker without a confirmed outdoor IP weather rating. Installing it in exposed outdoor positions, areas subject to rain ingress, or high-humidity environments risks damage to the driver and electronics. A purpose-built weatherproof IP-rated outdoor speaker is the correct product type for those applications.

6. Does the 5.25-inch driver size affect audio quality compared to smaller speakers?

   Yes, meaningfully. A 5.25-inch driver moves more air than a typical 3-inch or 4-inch ceiling speaker insert, which improves low-frequency response and overall volume consistency at distance. For voice intelligibility - particularly for spoken announcements in large rooms - a larger cone reduces the harshness and distortion that smaller drivers produce when pushed toward their limits at 20W power levels.
