I was skeptical about buying security cameras online. But I gave it a go. I had a residential CCTV installed by Cameras R us very recently. The guys turned up at the scheduled time, they worked professionally, tidily and the installation was top-notch. I was then taken through the system before they left and was even shown a demo on how to use, quick fixes and where the CAT5 cables were run and stuff like that Overall, a professional highly skilled company, would definitely recommend and use again.
