Surveillance technology company Digital Barriers made four acquisitions during 2011, including those of Stryker Communications in November for up to £1.5 million, and Keeneo in August for €2 million.

LMW provides video capture and transmission technology to the international law enforcement and military markets trough products such as ruggedised video cameras and outstations.

According to a statement, the board of Digital Barriers believes that LMW’s product set and technology are complementary to those already offered by the London-headquartered business.

Under the terms of the deal Digital Barriers is to acquire the intellectual property, products, stock, goodwill and certain customer contracts of LMW for a consideration of £450,000 in cash.

Earlier in 2011 Digital Barriers agreed a deal which could see it pay a total of £10 million for Cambridgeshire-based Zimiti, a company which provides surveillance and protective applications in the defence and security sectors
