Hi I have a career/jobish question. My family just bought a small local hotel and we want to replace the security system with a new one; the old one was too simple and some cameras don't even work. Unfortunately, none of our family members know much about cctv systems and business security, so we're thinking of letting an engineer handle it. Is there a specific name for this job position and does it require he/she to have particular skills/ background? Thanks!
