Sira Defence and Security's roots can be traced back as far as 1918 when the Scientific Instrument Research Association was formed. The association was responsible for all areas of optics development during the wars and continued this through to the 1970s when the association was renamed Sira Ltd. Sira Defence and Security Limited was formed when the Defence and Security sector of Sira was purchased by the Volvere Group in 2006. The company now concentrates on developing products to help the Police use CCTV effectively. We are a team of hardware and software engineers. Due to our measurement and instrumentation background, we have a particular emphasis on providing accurate information. For our CCTV products, great care is always taken to ensure that any CCTV information is reproduced as accurately as possible and to an evidential standard.
