Home Security Systems questions, answered by experts

The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:

  • Video surveillance monitoring: $40–$65 per month

  • Smart home locks: $150

  • Smart home lighting: $15–$90

  • Smart smoke, fire, and carbon monoxide alarms: $35–$100

  • Smart thermostat: $130–$500

Leaving a light on at night probably does not deter burglars as much as we would like. While there isn’t much evidence supporting the theory that lights deter burglars, there’s not anything disproving it either. If you feel like it offers added security because a burglar thinks you’re at home, then you can set your lights to a timer so they go off and on at intervals, mimicking someone moving around inside the house at night. A better idea is to install motion sensor lights in your yard.

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

Expect to spend an average of $150 to $500 to set up a home flood detection system. However, be aware that costs are wide-ranging. You might only spend a budget-friendly $50 to place basic, battery-operated sensors in a few key areas of your home, or $150 to set up two or three smart sensors. The purchase and professional installation of a whole-home protection system with water shutoff capabilities could cost between $500 and $1,000.

When deciding whether a home automation system is right for you, consider the advantages and disadvantages first.

Pros

  • Home automation can help make your home more energy efficient, possibly lowering utility bills.

  • A wide range of automated solutions is available to meet your needs.

  • Centralized and remote control of different home automation systems.

Cons

  • Home automation can be costly.

  • Not all automated systems are compatible with each other.

  • Over-dependence on home automation can be problematic if systems cannot connect to the cloud.
