Could anyone recommend a route to gain knowledge about access control and cctv, we've always used a sub contractor to carry out our works, but eventually you have to think, why can't we do this? It's not something I'd be willing to just have a bash at. The standard of some of the installs are appalling, so if I can carry out the work and bring it upto the correct standard then it would be better all round, rather than just lashing cables in as the crow flies!!
