Cambridge Sound DS2500 70V window, door, wall masker for SCIF / secure rooms - 911.0810.900

Product Overview

The Cambridge Sound DS2500 is a Dynasound 70V window, door, and wall sound masker, part number 911.0810.900, engineered for SCIF and secure-room eavesdropping protection. It attaches to the interior side of windows, doors, and in some cases wall surfaces, applying full-bandwidth sound masking while leaving the surface intact. The DS2500 series is a critical element for securing perimeter surfaces when DIAM and DCID requirements for SCIF must be met.

Product Description

Windows and doors are the most vulnerable surfaces in a secure room: laser eavesdropping techniques can read window vibration from a distance, and parabolic microphones can capture speech leaking through doors and glazing. The DS2500 defeats these threats by vibrating the protected surface with a masking signal, making any recovered vibration unintelligible. The unit is designed for 70.7-volt distributed systems and does not require a separate transformer, which keeps wiring simple across many maskers on one amplifier line. It is lightweight, installs with a UV-rated adhesive mount, and is available with or without a rotary switch. The masker accepts a mix of sound masking, music, and misinformation signal content. When controlled by Dynasound DS102 Series security generators and amplifiers, the DS2500 also protects against sophisticated signal recovery techniques designed to capture conversations buried within the masking signal. For a version with in-line volume control and retractable cord, see the DS2530 in the Cambridge Sound collection at Creation Networks.

Key Features

• Window, Door, and Wall Protection — defends perimeter surfaces against human and electronic eavesdropping techniques.
• Laser and Parabolic Countermeasure — effective against laser eavesdropping and parabolic microphone capture.
• Surface-Safe Mounting — attaches to the interior side of windows and doors with a UV-rated adhesive mount; surface integrity remains intact.
• 70.7V Design, No Transformer — built for 70.7-volt systems with no separate transformer required.
• Lightweight Installation — easy to install across many openings in a secure perimeter.
• Flexible Signal Content — accepts a mix of sound masking, music, and misinformation signal.
• Rotary Switch Option — available with or without a rotary switch for local adjustment.
• DS102 Series Compatible — pairs with Dynasound security generators and amplifiers to resist advanced signal recovery.

Typical Applications

The DS2500 is deployed in SCIFs, embassies, military and intelligence facilities, and corporate boardrooms with eavesdropping concerns. It treats exterior windows exposed to laser surveillance, doors onto uncontrolled corridors, and wall sections along the secure perimeter, supporting DIAM and DCID accreditation requirements.

Frequently Asked Questions

What threats does the DS2500 counter?

Human and electronic eavesdropping against windows, doors, and walls, including laser eavesdropping techniques and parabolic microphones.

Does it damage the window or door it protects?

No. The unit attaches to the interior side of the surface with a UV-rated adhesive mount, and the integrity of the surface remains intact.

Does the DS2500 need its own transformer?

No. It is designed for 70.7-volt systems and does not require a separate transformer.

How is it different from the DS2530?

Both protect windows, doors, and walls; the DS2530 adds an in-line volume control and retractable cord, while the DS2500 is offered with or without a rotary switch.

Is it appropriate for SCIF accreditation?

Yes. The DS2500 series is critical to securing windows, doors, and walls when DIAM and DCID requirements for SCIF need to be met.
