Home Security Systems questions, answered by experts

Faulty sensors, weak signals, false alarms, and control panel malfunctions are common problems requiring repair.

The main difference between different security sensor options is the type of motion each detects. A motion detector monitors obvious movements in hallways, entrances, and exits. On the other hand, a presence detector is more sensitive and captures smaller moves. A window sensor typically focuses on the opening and closing of the window, whereas a glass break sensor alarms you when a glass is broken.

It depends on the type of sensor your home security system uses. If it’s a motion detector, any moving thing could set it off, from a roaming pet to a wind-blown curtain. Contact sensors would be triggered by the window being opened or moved. Also, be aware that any sensors placed too close to your vents could trigger false alarms whenever your heat or air conditioning is running.

Professional home automation services can include automation for nearly anything in your home, so the possibilities are endless. Some of the more common things homeowners use automation for include the following:

  • Heating and cooling for automatic comfort

  • Security cameras and emergency call systems

  • Door and window sensors to detect opening, closing, and break-ins

  • Solar system automation to maximize energy savings

  • Automatic door locks

  • Garage door openers

  • Speaker systems

  • Lighting

  • Appliances

  • Smoke and CO detectors

  • Blinds and other window coverings

  • Lawn irrigation systems

  • Water monitoring

A keypad deadbolt, a lock requiring a code entered on a keypad entry, can be a convenient option for families with children coming in and out and needing access to the home. It can also offer an easy solution if you rent your home out, since you can easily change the code as needed. So, depending on your home entry’s needs, a keypad deadbolt may be worth the extra expense.
