Residence, Penthouse & Mansion Sweeps
Your home is the one place you should be able to let your guard down. BlackSweep performs the complete sweep of high-end residences, penthouses, mansions and country houses to locate hidden cameras, bugs, microphones and transmitters — powered or unpowered — with total discretion.
Detection of hidden cameras in bedrooms, closets, bathrooms and living areas
Real-time RF spectrum analysis (Rohde & Schwarz, Aaronia, REI OSCOR)
Non-linear junction detection (NLJD): finds electronics even when off
Thermography (FLIR) and meticulous physical inspection, from décor to infrastructure
Private report + technical report + hardening plan — under confidentiality
When should you sweep your home?
After renovations, service providers, moving, short-term rentals or hosting third parties; during separations and family disputes; or whenever you suspect your privacy is being watched. For those with high exposure, we recommend scheduled periodic sweeps.
What you receive
A clear, objective private report and a detailed technical report with evidence. If a device is found, we produce full forensic documentation — photos, location and identification — plus a hardening plan to reduce the risk of new threats. All under a confidentiality protocol.
