"Andrew Brown from Alarm Protection Group facilitated the installation of our home security system. He was a very helpful and informative, and was not pushy, as with other ADT sales reps. He followed up with us after the system was installed to see if we had any questions or concerns re the system. I highly recommend Andrew to anyone who is interested in a home security system."

Home Security Systems questions, answered by experts

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.

Some Christmas lights are marked as being “UL Safety Certified” or Underwriters Laboratories Safety Certified. This lab is a trusted source for determining the safety standards of electrical products—you should make sure your Christmas lights have this label. Brush up on other electrical safety tips before installing any lighting features. 

The cost of home automation averages around $1,000, with most projects falling between $200 and $2,000. The total cost depends on several factors, including the level of automation, brand, system features, home size, and location. For a DIY approach, basic home automation technology can cost between $100 and $500, though the scope and interaction between products may be limited. High-end, all-inclusive systems for larger homes can cost anywhere from $10,000 to $150,000, especially when they include smart appliances like refrigerators and dishwashers that require extensive wiring. Additional costs, such as subscriptions for maintenance services, can also impact the total price. It's often helpful to set a budget and consult with an expert to determine the best options for your home.

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

This is the topic of much debate, though there is no “better,” as it depends on personal preferences. Some of the components of a wireless system keep working when the power goes out, as they are battery-powered. On the other hand, a wireless system typically connects to your modem and router. Wired systems use landlines to communicate, which never go out on their own unless they’re physically cut.
