The company says it has seen some "terrible installations" in the industry and urges customers to use its business service partner (BSP) network of approved technicians.
Brigade's Emily Hardy says examples of poor quality installations have included "cameras mounted upside down, or not positioned to view the blind spot, directional white sound reversing alarms facing the wrong way and sensors fitted in unsuitable positions".
She adds: "Fitters have left exposed cables, cut connectors and taped joints or used scotch locks which eventually leads to wires failing. Holes in body work are often not sealed and this leads to water ingress and rusting. For all of these reasons we use our business service partners to ensure quality installs."
Each BSP is an approved Brigade distributor and they often work together to provide the best service.
In Scotland, for example, MTH Auto Services, in Falkirk, makes its workshops and pits available to other BSPs north of the border, which are Banlaw Systems of South Lanarkshire and Aberdeen-based Taylors Auto Electrical. All three have a team of mobile service engineers.
All BSPs share information on issues and resolutions, says Hardy: "We see the BSP's as an extension of our own engineers."
As well as BSPs, Brigade has a nationwide network of approved fitters, mobile engineers and 150 distributors.
