A Security or Fire Alarm Installer is a person who holds himself out directly or indirectly, as being able, or who offers or undertakes, by any means or method, to install, service or maintain a security or fire alarm system to detect intrusion, break-in, movement, sound or fire. Installing an indoor camera can be as easy as finding the right spot, plugging it in, turning it on, and syncing it with your mobile or desktop app. While some may require drilling, most indoor cameras we've come across won't require anything more than a screwdriver.
