Wireless technology you can trust

Data radio communication at low powers within or between buildings is a problematic area, with many pitfalls for the unwary Designer and User.

The Hanwell wireless monitor system embodies 25 years of engineering expertise in this area to ensure best possible performance with a reliability that is guaranteed. This, coupled with an unrivalled ability to plan and install robust systems, means that you can trust what we say. This is evidenced by many thousands of systems using our technologies in use worldwide today, with many still operating after 20 years.

Unfortunately, wild claims are easy to make but they do not substitute for real expertise. We are more than happy to prove our claims to you at any time before purchase, just please make sure that you ask the same of all potential vendors.
