RF & EMI Shielding for Evidence Storage

RF shielding for law enforcement evidence storage rooms has to be precise, secure, and inspection-ready from day one. We deliver a complete design package so your evidence receiving area, secure storage vault/room, interview/processing adjacent spaces, and any digital-evidence shelving stay on schedule, on budget, and protected from RF exposure that can enable unauthorized wireless access, interfere with device isolation, or put chain-of-custody integrity at risk.
Before/After

Evidence storage room shielding that passes inspection the first time.

Full-scope RF shielding design for law enforcement evidence storage: engineered performance targets, permit-ready drawings, and trade coordination for clean installs—so seized devices and sensitive evidence stay isolated from wireless access, tampering-by-signal, and the interference that can complicate chain-of-custody.

RF Shielding for an evidence storage room

One team, from concept to closeout

Don’t gamble with chain-of-custody by settling for “good enough” RF shielding. We deliver end-to-end shielding design and implementation support for law enforcement evidence storage rooms—so seized devices and sensitive evidence stay isolated, your build stays controlled, and your room is ready for verification the first time.

Fewer Change Orders, Smoother Construction
Our evidence-room shielding details are built for the field: clear wall/ceiling/floor assemblies, coordinated drawings, and practical install guidance. That means fewer surprises, less rework, and tighter schedule control.
Code-Ready, Inspection-Ready Deliverables
We produce calculations, drawings, and design packages aligned with applicable standards and agency requirements. The result: a cleaner path to approvals, verification testing, and final turnover.
Faster Turnarounds for New Labs and Retrofits
Whether you’re building a new evidence storage vault or upgrading an existing room, we keep scope tight and decisions fast—so you can get operational sooner without sacrificing performance.
Coordination for MEP, Doors, and Penetrations
Shielding succeeds or fails at the details—HVAC, electrical, conduit, data cabling, access control, cameras, pass-throughs, and grounding/bonding. We coordinate the interfaces so the room performs as designed, not “as patched.”

Evidence Storage Room Shielding FAQ

To protect stored evidence—especially electronic evidence—from unwanted RF signals and electrical noise that can cause device communications, interfere with tracking/monitoring electronics, or create avoidable risk around evidence integrity.

Most commonly:

  • Electronic evidence storage (phones, laptops, tablets, IoT devices)
  • High-profile / sensitive case evidence rooms
  • Storage areas near radio rooms, dispatch, roof antennas, or dense IT/power infrastructure
  • Rooms where scanners, inventory systems, or security electronics are affected by interference

Both. Many agencies want to:

  • Reduce external cellular/Wi-Fi/Bluetooth reaching devices in storage
  • Prevent signals from stored devices from leaking out of the room

    The right direction (or both) depends on your operational requirements.

Often, yes. Bags/lockers help—but they depend on perfect, consistent use and maintenance. Room-level shielding provides a baseline level of control that doesn’t disappear when a bag seal fails, a device is oversized, or a workflow gets rushed.

A complete RF/EMI control solution typically includes:

  • Continuous shielding on walls/ceiling (and sometimes floor)
  • A shielded, gasketed door/door frame assembly
  • Treated penetrations for power, fire alarm, access control, cameras, and data
  • Proper bonding/grounding strategy for the shielding system
  • HVAC airflow solutions that don’t create RF leaks (e.g., waveguides/honeycomb vents)

The usual suspects:

  • Door alignment, worn gaskets, or poor door hardware
  • Late-added conduit/cables (“just one more penetration”)
  • HVAC openings not treated correctly
  • Inconsistent bonding/grounding
  • Gaps at corners, seams, or transitions above ceilings

Not if it’s planned correctly. We coordinate security and life-safety early so access control, monitoring, and required systems function normally—without compromising shielding performance.

Yes. Retrofits are common. The key is a quick site assessment to identify existing penetrations, ductwork, door constraints, and adjacent RF sources—then designing a solution that doesn’t blow up the schedule.

Send any of the following and we can move fast:

  • Room dimensions + photos (or architectural plans)
  • What’s being stored (electronics-heavy vs mixed evidence)
  • Any agency requirements or internal SOPs for device isolation
  • Known penetrations (HVAC, power, fire, security, data)
  • New build vs retrofit + timeline
