Here at Sewell we've been making IR repeaters for a long time (I want to say five years but time goes so fast these days it's also possible that it's been eight or something ). One of the most common scenarios we've seen is that people have a cabinet in their living room with their AV equipment in it and they open the cabinet door every time they want to use their remote.
IR over HDMI (InjectIR)
When we started selling the InjectIR a few years ago (it lets an IR signal hitch a ride on an HDMI cable via the CEC channel with an emitter at the end to control your hidden equipment) we figured the problem was solved. Unfortunately, though, that doesn't really work for people who have other uses for the CEC channel (which goes by a thousand different names since each OEM tries to brand it as their own technology). In some cases people already have the TV installed and taking the TV down to install an InjectIR would be more trouble than it's worth.
In this case we would always recommend a traditional IR repeater, but it just felt like overkill when a person needs to go less than ten feet in the same room. They don't need multiple receivers or emitters and finding a convenient power supply without creating more cable clutter can be hard.
The Ghost IR Repeater is born
About a year ago Brett, the Sewell Product Manager behind many of our most popular products, decided to tackle the problem by creating a battery-powered, short-throw repeater to get an IR signal to fix this problem. He worked with an engineer to ensure it would be easy to install, reliably replicate all IR signals including RC-MM and be efficient enough to last for more than a year with moderate use (with light use it should last up to two years). Also, when the battery dies the user the can easily change it themselves with a standard CR2032 coin cell battery.
We soft-launched the product a few weeks ago meaning mostly just our friends and family know about it, but we wanted to let you guys know about it since this is probably a common problem people on AVS forum have either dealt with themselves or have friends/family members ask about.
Our stock is limited, but if somebody asks really nice we'll hook you up with one in exchange for some feedback
