Sensors & Detectors

Monitor Your Home

There are multiple types of sensors available with your Midco SmartHOME™ security system.

  • Door/window sensors monitor the opening and closing of potential entry and exit points for your home.
  • Motion detectors monitor movement within the premises.
  • Carbon monoxide sensors and smoke detectors trigger an alarm if smoke or CO is detected.
  • Flood sensors trigger an alert if water comes in contact with the sensor.
  • Glass break sensors trigger an alarm if glass is broken.

You can use a maximum of 64 security sensors and environmental devices with your home security system. You cannot add or delete security sensors in your security system without a visit from a Midco technician, but you can control how they appear on your touchscreen and online portal.

While our technicians will help you determine the best places to put sensors and detectors, it can help for you to have an idea prior to installation of where you want your sensors in your home.

We recommend you install door and window sensors and/or glass break detectors at every possible location of entry – both upstairs and down. Here are some other tips.

  • Avoid mounting glass break detectors in corners, on free-standing posts or pillars, in rooms with noisy equipment (such as air compressors, bells and power tools) and in bathrooms (a slamming toilet seat will fault a glass break detector).
  • Anticipate traffic patterns when placing motion detectors.
    • The lanes of traffic most used by people in your home are also those most likely to be used by intruders.
    • Foyers, stairways, hallways and entrances are excellent locations for motion detectors.
    • For best coverage, place motion detectors so that the intruder will walk across a detector’s pattern – not directly toward or away from the detector.
    • Motion detectors facing the following could cause false alarms or failures in detection: direct sunlight, cold drafts, windows, uninsulated walls, heat sources such as fireplaces and heating vents, moving objects such as fans, air conditioning vents, glass furniture, and obstructions such as curtains, potted plants, and doors.
  • Pets can cause special problems for motion detectors. If you have a pet, make sure to install our pet-friendly motion detectors in your home to avoid detecting pets up to 85 pounds.

You can turn a zone off – meaning the zone isn’t monitored when the system is armed. This is useful at times, such as if you’re active in only one area of the house but want the rest of the system to be armed. You can only disable a sensor when the system is disarmed.

Your system will continue to log the activity in zones that are turned off in your Event History. Note: Water sensors and smoke and CO detectors cannot be turned off.
