In this category you will find Eavesdropping devices for landline phones, ISDN connections and VOIP systems. Our selection ranges from compact telephone mini transmitters with radio transmission to wired recording adapters and digital telephone recorders. This way you get the right solution for every requirement for discreet landline surveillance.
Our smallest telephone transmitters in micro format – some no larger than a pea – enable covert monitoring of analog conversations. For ISDN telephony, we offer powerful 2-channel mini transmitters that work reliably and unobtrusively. This allows conversations to be easily and discreetly recorded or transmitted live.
For seamless landline surveillance various wired solutions are available. These include ISDN recording adapters as well as digital telephone recorders with particularly long runtimes. These systems are reliable, low-maintenance, and can be used flexibly – ideal for permanent use.
In addition to compact mini transmitters and recorders, we also offer PC-based monitoring systems. These enable convenient management, long-term recording, and easy evaluation of telephone conversations. This provides you with all the technical possibilities to conduct effective and secure telecommunications monitoring.

Discover our selection of devices for landline monitoring now and order powerful eavesdropping technology for analog, ISDN, and VOIP telephony – discreet, secure, and reliable.
The choice of the appropriate landline eavesdropping technology strongly depends on the type of connection. While analog lines are relatively easy to monitor, ISDN and VOIP systems require significantly more technical planning. A wrongly chosen solution often leads to incomplete recordings or unstable operation.
Technical note:
In VOIP telephony, the router determines the monitoring possibilities. Without compatible interfaces or software support, conversations often cannot be fully captured.
