"My company has an offsite warehouse way out in the country about 15 miles from our main office. We wanted to add surveillance at the warehouse so we don’t have to go out there to check on things as often. We purchased an adt camera package and it has really helped cut down on our travel time. Simple but effective way to add surveillance to our storage warehouse."

Home Security Systems questions, answered by experts

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.

A security camera company will be able to advise you on where to position the cameras, ensure all of the equipment is set up properly, and do all of the installations. They’ll take factors into consideration that a non-professional might not automatically consider, like obstacles that could block a potential trespasser from the camera or how lighting may obstruct the view.

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.

Costs depend on issue complexity, labor, replacement parts, and system age.

Find a vetted and trusted locksmith to work on your home so you can feel comfortable and safe. Hire a professional with these qualifications:

  • Search a verified directory of locksmiths near you, like those on Angi. 

  • Check for an Associated Locksmiths of America (ALOA) logo on their website or company logo.

  • Read company reviews. You can also check their social media pages.

  • Ask for a pro’s credentials, insurance, licensure, and customer testimonials. 

  • Check if the locksmith is knowledgeable about various topics, from decorative locks to the newest technologies on the market.
