Most homeowners install their own surveillance cameras, but it is possible to hire a professional security company to install them for you. If you're having trouble installing your own cameras, it's best to contact a reputable security services provider for assistance. If you share hallways and stairwells with your neighbors in a condo complex or apartment building, check with your landlord or property manager about installing cameras in these areas before you start drilling holes in walls or ceilings without permission!
