Though old school security systems were limited in their size and scope, modern systems have a host of extras that you can use to improve your experience.

For example, the access control system is available in various levels of security. A keypad number is the lowest level, because it can easily be used by someone else who has discovered the number. Hardware engagement would be the next level; either a card or fob in most cases. Most homes will not require anything more extensive than these levels.

Smoke alarms and detectors often go unnoticed until it is too late. However, our experts can ensure the best organization possible to ensure first responders get to your home quickly in the event of a fire.
