Cambridge Sound DS2508 Network window, door, wall masker for SCIF / secure room - 911.0811.900

Product Overview

The Cambridge Sound DS2508 (part number 911.0811.900) is a Dynasound network surface masker that protects windows, doors, and walls against human and electronic eavesdropping by applying full-bandwidth sound masking directly to the surface. It attaches to the interior side of any window or door — and in some cases wall surfaces — while leaving the integrity of the surface intact. The DS2508 series plays a critical role in securing perimeter surfaces when DIAM and DCID requirements for SCIF construction must be met. It is effective against laser eavesdropping techniques as well as parabolic microphones.

Product Description

Where ceiling emitters mask speech within a space, the DS2508 masks the building surfaces that sound can travel through or be intercepted from. Mounted with a UV-rated adhesive on the interior face of glazing, doors, or walls, it injects masking energy into the surface itself, defeating both direct listening and electronic techniques such as laser vibrometry aimed at window glass and parabolic microphones aimed at the building envelope. The unit is designed for the DynasoundPro networked sound masking system, allowing centralized control of masking levels across all protected surfaces in a secure facility. It accepts a mix of sound masking, music, and misinformation signals, giving security designers flexibility in how each surface is protected. The masker is lightweight and straightforward to install, and because it adheres rather than penetrates, it does not compromise window or wall assemblies. For complementary in-room masking, see the emitters and control modules in the Cambridge Sound collection.

FAQ

How does the DS2508 differ from ceiling emitters?
Ceiling emitters mask speech within the room; the DS2508 attaches to windows, doors, and walls to mask the surfaces themselves, blocking interception paths through the building envelope.

Is it suitable for SCIF construction?
Yes. The DS2508 series is used to secure windows, doors, and walls where DIAM and DCID requirements for SCIF must be met.

Does mounting it damage the window or wall?
No. It uses a UV-rated adhesive mount on the interior side of the surface, and the integrity of the surface remains intact.

What signals can it carry?
It accepts a mix of sound masking, music, and misinformation signals, configurable through the DynasoundPro networked system.

Does it stop laser eavesdropping?
Yes. It is effective against laser eavesdropping techniques on glazing as well as parabolic microphone interception.
