Just be aware, there are lots of "security" companies who hire mostly clowns to do their grunt labour and work them into the ground... so if you have half a clue, you'll end up being very, very frustrated very quickly. Lot of them are just looking for the best margins they can get, so they want you to slap stuff in as quick as possible... then when things fuck up three months later and the company is taking forever to respond to customer service calls, you're the one who gets yelled at when you're finally dispatched to fix things.

Moral of the story: when you're looking for somewhere to work, do your homework... ESPECIALLY in this industry, since the regulations are so vague. Electricians, plumbers, etc. all have tons of regulations and qualifications you have to pass before you can do the work... low-voltage, not so much.
