In some cases Google rewrites the title of web pages in its search results pages. Here is the exact answer from a Google Employee about this issue:
In general, when we run across titles that appear to be sub-optimal, we may choose to rewrite them in the search results. This could happen when the titles are particularly short, shared across large parts of your site or appear to be mostly a collection of keywords. One thing you can do to help prevent this is to make sure that your titles and descriptions are relevant, unique and compelling, without being "stuffed" with too much boilerplate text across your site.

In your case I believe Google decided that your page is also relevant for the keyword "CCTV Cameras" and added that to the page title.
