Delta S Countersurveillance Sweeping System

Frequently Bought Together


      The Delta S is an easy to use sweeping system that reliably detects all types of RF surveillances up to 6 GHz, with a special mode to detect cellular jamming devices.  The Delta S also has a background masking feature which will reject friendly known signals such as television, radio, mobile base stations, etc., making it even easier to detect unwanted GSM, 3G, 4G / LTE, 5G, Bluetooth, WiFi, DECT and all others in the range up to 6 GHz.



      • Quickly and reliably detects all types of RF surveillance devices in the range up to 6 GHz, including analog, digital, working continuously and periodically, transmitting audio or video, with or without encryption
      • Finds and identifies covert surveillance devices which use the digital standards GSM, 3G, 4G / LTE, 5G, Bluetooth, Wi-Fi, DECT and others in the range up to 6 GHz
      • Analyzes Wi-Fi 2.4 GHz, Wi-Fi 5 GHz, Bluetooth, “Bluetooth LE” and “Bluetooth LE Advertising” channels
      • The background masking feature allows you to reject friendly signals such as television, radio, mobile base stations, etc., and focus on finding local signals that pose a danger
      • Can be quickly adjusted to the local frequency allocation in the country of use (mobile and wireless bands)
      • High-speed spectrum updating and wide real-time bandwidth (RTBW) provide the ability to register short-burst signals
      • Search modes include: "All Signals", "Mobile/GPS trackers", "Wireless/ISM" and "Custom", as well as two additional modes for the inspection of suspicious bands or signals
      • Two antenna inputs and built-in antenna switch provide maximum sensitivity over the entire frequency range
      • Unlimited number of logs, each can contain an unlimited history of events
      • Unlimited number of logs, each can contain an unlimited history of events
      • The audio alarm warns the user about the presence of danger with a sound of variable intensity
      • The attenuator simplifies location of powerful transmitters
      • The "Hold maximum danger" feature automatically displays the most dangerous band or signal
