The AXIS T8355 Digital Microphone is a network-ready audio accessory designed for use with compatible Axis surveillance devices. Featuring built-in noise reduction and digital audio transmission, it delivers clear sound capture for speech and environmental audio monitoring. It suits a variety of indoor surveillance environments where reliable audio capture is required.
Key Features
Digital Audio Transmission: Delivers high-quality sound capture with reliable digital signal output.
Built-In Noise Reduction: Filters background noise to improve clarity of captured audio.
Network-Ready Design: Compatible with Axis network devices for seamless integration into existing systems.
Speech and Environmental Audio: Suited to capturing both voice and ambient sound in monitoring environments.
Adding audio to a network surveillance installation requires more than plugging in a generic microphone. The AXIS T8355 Digital Microphone (01561-001) is designed as a network-ready audio accessory built specifically for integration with compatible Axis network cameras and recording platforms. It converts captured sound into digital audio for transmission over network infrastructure, reducing the electrical noise and interference associated with traditional analog audio connections. Featuring built-in noise reduction and a compact form factor, this microphone can be placed discreetly near a camera or at a specific point of interest such as a reception counter, entrance, or monitored zone. It supports both continuous and event-triggered audio capture, making it suited to commercial, industrial, and public safety environments where synchronized audio and video surveillance is a priority.
Key Capabilities
Digital Audio Transmission
By converting acoustic audio into network-ready digital data, the T8355 avoids the noise and interference common to analog audio connections, delivering cleaner recordings that hold up better during incident review and analysis.
Built-In Noise Reduction
Integrated noise reduction filters out unwanted background interference, allowing speech and meaningful environmental sounds to come through more clearly even in busier or louder surveillance environments.
Axis Ecosystem Compatibility
Engineered to work within the Axis network camera ecosystem, the T8355 integrates with compatible cameras and recording systems for synchronised audio and video capture without requiring additional conversion hardware.
Compact, Discreet Form Factor
The small physical profile allows the T8355 to be mounted close to a camera or positioned independently at a specific audio capture point, keeping installations tidy without compromising audio coverage.
Best For
Axis Camera Installations Requiring Audio: Designed specifically for compatible Axis network cameras, making it the direct choice when audio needs to be added to an existing or new Axis deployment.
Environments Where Verbal Interaction Matters: Reception areas, enquiry counters, and monitored entrances where capturing speech alongside video improves incident context and evidence quality.
Sites Needing Event-Triggered Audio: Supports both continuous and event-triggered capture, useful for installations where audio analytics or alert workflows are part of the surveillance design.
Why Choose the AXIS T8355 Digital Microphone
The AXIS T8355 is not a general-purpose microphone adapted for security use. It is a purpose-built network audio accessory designed for Axis surveillance deployments where audio quality and system integration both matter. The digital output avoids the degradation and hum that can affect analog audio over longer cable runs, and the built-in noise reduction makes it more practical in real-world environments that are rarely quiet. Its compact size means it can be placed at the exact point where audio capture is needed, whether that is beside a camera, above a counter, or within a monitored corridor. For integrators and end users who have already committed to the Axis ecosystem, the T8355 delivers audio that works within that framework without workarounds. It is available through Security Wholesalers as part of the Axis accessories range.
Buyer Decision Tips
Buyer Tip: Before purchasing, confirm that your specific Axis camera model supports digital audio input. Not all Axis cameras include an audio input port, and the T8355 is designed for compatible devices only. Check the technical specifications of your camera against Axis compatibility documentation to ensure the microphone will integrate correctly with your system before installation.

Ideal Use Cases
Reception and Front-of-House Areas
Placed near a reception camera, the T8355 captures verbal exchanges and ambient audio to give operators fuller context around interactions and incidents that video alone cannot fully convey.
Retail Premises
Audio captured alongside video in retail environments supports incident verification by providing spoken context, which can be valuable when reviewing footage for loss prevention or staff safety purposes.
Public and Shared Spaces
In lobbies, corridors, and communal areas where Axis cameras are already deployed, the T8355 adds an audio layer that improves situational awareness for monitoring staff and control room operators.
Industrial and Commercial Sites
In areas where unusual sounds may signal a safety or security event, the T8355 provides a digital audio input that can feed into event-trigger workflows alongside existing Axis camera systems.
Choosing the Right Model
Choose this model if: You are adding audio to an existing Axis camera installation and need a network-ready digital microphone with built-in noise reduction that integrates natively within the Axis ecosystem.
Choose a different model if: Your cameras are not Axis devices or do not support digital audio input. A general-purpose analog microphone connected via an audio encoder may be more appropriate for non-Axis or mixed-brand installations.
Choose a different model if: Your installation requires outdoor audio capture in exposed conditions. Confirm the T8355’s rated environment before deploying in locations subject to weather exposure.
FAQs
What is the difference between a digital microphone and an analog microphone for surveillance use? A digital microphone like the T8355 converts audio into a digital signal before transmission. This reduces susceptibility to electrical interference and noise that can degrade analog audio, particularly over longer cable runs. The result is cleaner audio that integrates more naturally with IP-based recording and analytics platforms.
Does the AXIS T8355 work with all Axis cameras? No. The T8355 is designed for compatible Axis network cameras that include a digital audio input. You should verify your specific camera model supports digital audio input before purchasing. Check the technical specifications on the Axis product page for your camera to confirm compatibility.
Can the T8355 be used to trigger events or alerts in a surveillance system? Yes. The T8355 provides a digital audio input that can be used alongside Axis software to configure audio-based event triggers. This allows the system to initiate a response or recording action when a sound exceeds a threshold or matches a defined profile, depending on the capabilities of your recording platform.
Where is the best physical location to mount the T8355? The T8355 is compact and can be positioned close to a camera or independently at a dedicated audio capture point. For speech capture, placing it near the point of interaction, such as a counter or entry point, will give the clearest results. Its small size allows discreet placement without being visually obtrusive. The T8355 is available through Security Wholesalers for use in professional Axis installations.
Does the T8355 support continuous recording or only event-based audio? The AXIS T8355 supports both continuous and event-triggered audio capture. The mode used will depend on how your recording system and camera are configured. Continuous recording captures audio alongside the video stream at all times, while event-triggered capture records audio only when a defined condition is met.
