Sepura's first TETRA radio was the SRP2000. This set new benchmarks in the industry as it was much smaller and lighter than anything that had gone before. Developed at a time when the UK Police were going through a uniform re design, Sepura listened carefully to police users’ requirements to develop a functional secure communications device that was fit for purpose. As a result, by mid 2004, the SRP2000 held a remarkable 90% of market share (Radio Comms News, 2012) among UK based police users. The SRP2000 resembled a GSM phone of the day, rather than a traditional portable radio and, for the first time, it was a radio designed to be worn on the user's lapel rather than on the belt. This was significant, because a lapel worn radio negated the need for a remote speaker microphone and removed a sizeable weight from the user's belt – a factor which was thought to contribute to lumbar strain and a significant number of absences from work. In 2005, Sepura partnered with QinetiQ to deploy the first use of Super Sensitive GPS for TETRA users, known as sGPS. This move saw the SRP series updated to become the SRH series.

Launched in 2010, the SRG3900 was a popular addition to Sepura's range, providing 10 watts of RF power, and gateway and repeater technology to extend communication into areas otherwise beyond network coverage. It had the greatest operational range of any TETRA terminal on the contemporary market and was deployed everywhere from ski resorts to mines and chemical parks. It was launched in conjunction with the Sepura Colour Console (SCC), whose large, high resolution colour screen allowed the display of high quality photographs and maps.

Launched in May 2015, the SC20 was promoted as ‘The next generation’ of hand portable radios, offering optional high speed data connectivity, connectivity to body worn data accessories and a Linux operating system to enable a wider applications capability. Submersible, waterproof and dustproof, SC20 radios passed IP66, IP67 and IP68 environmental protection ratings and were designed with an easy clean design, allowing them to be rinsed in running water. In May 2017, the more compact SC21 hand held radio launched offering the same functionality as the SC20 but in a smaller radio terminal. In June 2019, the SCG22 mobile radio was launched. In June 2022 to enable more mining users to use Sepura TETRA radios, the SC20, SC21 and SCG22 were also made available in VHF, operating within 136 174MHz.

The first of Sepura's mission critical LTE products, the SCU3 Broadband Vehicle Device was launched at Critical Communications World Conference and Exhibition in November, 2021. Designed to provide both mission critical voice and access to high speed data, the SCU3 was built on an Android operating system, supporting Bluetooth, Wi Fi and Ethernet to provide connections to a wide range of accessories, apps and systems. The SCU3 received certification from the Global Certification Forum(GCF) in February 2022, meeting the GCF's technical requirements for interoperability of wireless devices. It also offers an optional TETRA Module, supporting Direct Mode in the 380 473MHz band for users wanted to use both TETRA and LTE networks.
