Signals Defense patented RF/IR window technology has been engineered to meet stringent US Intelligence community security requirements for facilities handling classified information. Our technology is the standard for the US government and corporations desiring to properly secure locations handling sensitive and/or classified information. Signals Defense window films meet the TEMPEST requirements for the intelligence community directive ICD 705 and the DoD Infrared and Radio Frequency Emanation Protection Standards.
Signals Defense's SD2500 RF Window film has been ASTM F3057-16 tested and exceeds Department of Defense requirements for RF attenuation. When considering IR and RF window film for your project, it is highly recommended that an appropriate test is considered for your security, a simple self-selected 6 frequency performance test, i.e. IEEE 299 test is not sufficient to understand the full attenuation capability of a material. Infrared attenuation is also critical for full anti-eavesdropping purposes. IR protection is a key component for defeating electronic espionage. Many "new" repurposed products today that have some limited protection against RF but have no or very little IR protection. From a TSCM (Technical Surveillance Counter-Measure) perspective, SD Films are the least expensive method to mitigate the largest amount of eavesdropping and espionage threats.
Signals Defense RF/ IR attenuating window films shield your building by:
- Rejecting RF/IR signals
- Preventing eavesdropping and theft of electronic data
- Defeating IR laser microphones and EMI/RF transmissions
- Providing blast protection
- Reducing UV/Solar emissions
- Containing surveillance/bugs
SD technology has been deployed in over 2,500 locations providing our clients with US DoD physical strength, IT, and emission security systems. SD Technology also provides safety and energy benefits to our clients with UV and glass fragmentation/spall control window films and SD glass/polycarbonate security solutions.
All Signals Defense window films have been rated by The NFRC. For a detailed technical spec sheet, samples of this or other products or for information about how this could secure your building, please order FREE samples here.

DAS Shield™
DAS Shield is an effective solution to RF interference in densely populated areas where in-building wireless is deployed for reliable cell phone service. DAS Shield™ is an architectural shielding technology which insulates a building from outside RF interference and allows in-building wireless solutions to work more effectively. DAS Shield minimizes Macro Cell interference with 4G LTE DAS deployments, especially in urban environments. It also provides added security for wireless technologies including WLAN or 802.11. DAS Shield is a low cost RF Window film alternative to provide adequate RF attenuation for buildings with small-cell Distributed Antenna Systems. It works by creating an RF separation at the glass to ensure cellular connectivity is made on the in-building wireless system. Learn more here
