"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

"This was the third company we contacted after having no follow through with the first two. I explained to Ramiro of Northbay Technology what our problem was. He had a technician here in a few days, he fixed the problem as well as giving us useful feedback on our system. Our streaming and dvd system work after not having it for almost 3 months! Ramiro also called afterwards to make sure everything was still working. What a treat to find a quality company that does what they say they’ll do and also offer great customer service."

Home Security Systems questions, answered by experts

One significant drawback of home automation is the increased risk of cybersecurity threats. With more connected devices in our homes, there's a greater chance that hackers might try to exploit vulnerabilities to access personal data or even control your devices. If you don't secure your smart gadgets properly, they can become entry points for cyberattacks, risking your privacy and safety. Moreover, technology isn't perfect. Sometimes, systems can malfunction or experience connectivity issues, disrupting your daily routines. The upfront cost of buying and installing smart devices can also be a hurdle for some people. 

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.

There are a number of ways to secure windows. You can add motion detectors or window sensors to detect movement and impact or change the window locks to make them stronger. Some of the ways you can secure windows are much like how you secure a home: closing the curtains at night and setting up security cameras outside so you can monitor your property even in your absence. 

If you're wondering what you should do with your old security alarm system after installing a new one, one option is to properly dispose of it at an electronics collection facility. Otherwise, if your old system is still in good shape, you can also donate it for someone else to use in their home.

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.
