NB: Please note that some of these devices will only work in the UK and Europe, but not in the USA due to the different GSM bands. Those that will operate in US are specified

This category contains a collection of the latest GSM Bugs (Infinity Transmitters) that Spy Equipment UK has put together to accommodate a varied range of applications and scenarios.GSM Bugs have been around for about four years on the spy market, so they are a relatively new concept. GSM Bugs can also be know as Infinity Transmitters and Spy Phone Bugs

These pieces of spy equipment use mobile phone technology that has been stripped down, adapted and enhanced to serve a particular purpose. Essentially they work in the same way as a mobile phone and as such contains a standard Sim Card. The GSM bug spy gadget is placed in an area where sound/voice needs to be monitored. The unit will sit there in standby mode silently waiting to be called. When the device is called, the call will be auto-answered silently and with no visual indication and the microphone will be activated so the caller can hear what is happening in the surrounding area. When the caller has finished listening in, then the call is ended in the normal manner and the GSM Bug will return to standby. Some advanced devices have facility for sound activation and have other features that can be manually or remotely set by SMS commands

Stand-alone battery-powered units are now very small and can be placed almost anywhere fairly discreetly. They have very sensitive microphones designed to have a large sound pick-up radius, so they are ideal for room monitoring or monitoring in a vehicle. The latest additions to the the GSM Bug range are fully functional mains-powered units. Spy Equipment UK has a number of these superb devices that have been fashioned into Double Plug Adapters, 4, 6 and 8 Gang Multi-plug Extension leads. We have even managed to incorporate Infinity Bugs into US and European style extension leads. These products have back-up batteries, so if they are unplugged, they will still function for a decent period of time despite being disconnected from their main power source. By replacing an existing Double Adapter, Extension Lead or Double Wall Socket with one of our devices, nobody would ever suspect

GSM Bugs are certainly expected to get smaller and more sophisticated in operation and eventually we should see battery life that should come somewhere near rivaling that of UHF Transmitters. To keep tabs on a wayward employee, a cheating partner or even your children, then GSM Bugs provide the perfect modern day solution
