In active mode, it detects devices currently transmitting. In passive mode, it identifies hidden electronics in standby using non-linear junction detection. This means even dormant surveillance bugs can be found.\u003c\/p\u003e\u003cp\u003eIts reflectometer sends a signal through the wire and measures how it returns. Any irregular reflection points to tampering, added connections, or breaks. This makes it especially useful in offices, secure facilities, and environments where communication integrity matters.\u003c\/p\u003e\u003cp\u003eThe built-in wired receiver listens directly to line activity, helping you locate unauthorized transmissions. At the same time, the low-frequency amplifier boosts faint signals, making subtle surveillance attempts easier to detect.\u003c\/p\u003e\u003cp\u003eCompared to manual inspection or basic detection tools, the ST-301 brings multiple detection methods into one system. Automated cable testing reduces effort, while included adapters and connectors let you work across different wire types without complex setup.\u003c\/p\u003e\u003cdiv\u003e \u003cimg src=\"https:\/\/www.spyshopeurope.com\/upload\/ST-301_Spider_Accessories_(1).jpg\" class=\"img-responsive\" alt=\"ST-301 Spider accessories and adapters\" border=\"0\"\u003e \u003c\/div\u003e\u003cp\u003eCovers many connection types for flexible real-world inspections.\u003c\/p\u003e\u003cdiv\u003e\n\u003cimg src=\"https:\/\/www.spyshopeurope.com\/upload\/ST-301_Spider_(1).jpg\" class=\"img-responsive\" alt=\"ST-301 Spider wireline analyzer device\" border=\"0\"\u003e \u003c\/div\u003e\u003cp\u003eGives direct insight into hidden activity inside wiring systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSecure your environment by exposing hidden threats inside your wiring.\u003c\/strong\u003e\u003c\/p\u003e","brand":"Spy-shop.com","offers":[{"title":"Default Title","offer_id":62377130721610,"sku":"SKU_1781691847795_710","price":12946.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0764\/5980\/2954\/files\/19438648.webp?v=1781691855","url":"https:\/\/spy-shop.com\/bg\/products\/st-301-spider-telephone-and-wireline-analyzer","provider":"Spy-shop.com","version":"1.0","type":"link"}
