"Jeremy came out to my house to explain 1st Security's system (co-branded system with alarm.com), and gave me an amazingly good deal with the best pricing possible. The thing that amazed me was that 1st Security's pricing (both upfront equipment cost and the monthly monitoring charge, with full access to smart phone system) was LESS than the do-it-yourself options like FrontPoint. Yes--it was less than FrontPoint, even though 1st Security's pricing includes FULL installation by a professional (Larry, who was amazing--spent hours at my house making sure everything was right and teaching my husband and me how to use the system). Even more amazingly, 1st Security's monthly rate (again, less than FrontPoint) includes service, meaning that there is NO house-call charge, the way there was with my previous alarm company. If anything breaks, etc., they will come out and fix/replace it! Jeremy and Larry were both awesome--helpful, courteous, professional, prompt, etc. I highly HIGHLY recommend them and 1st Security. If you're thinking of going with a DIY alarm company to save money, don't bother--call 1st Security. They will also match other companies' prices!"

Home Security Systems FAQs, answered by experts

Options include wired or wireless systems with night vision and motion detection.

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.

The benefit of deadbolt locks is that they're much harder to force open than simple locks with pin tumbler mechanisms, so they may offer added security. This feature is why many locksmiths recommend deadbolts for home security. For many households, this added protection and peace of mind is well worth the cost of installing a deadbolt.

Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.

While security hubs can streamline the management of security cameras, the placement of cameras itself is often determined by factors like your property layout, security objectives, and areas of concern.
