"Bill, the owner, and Brandon, the technician, both provided world-class customer service from start to finish. To begin, Bill stopped by to perform the in-home consultation and provided recommendations on how he could bring my vision to life with indoor/outdoor security cameras. Brandon did an outstanding job with the installation of all of my Google Nest cameras, assisting with camera placement for the best viewing angle, seamlessly fishing the power cables through the walls, and adding a classy touch by installing brush pass-through wall plates. Brandon managed smaller details such as the cable management for the outdoor camera above my garage flawlessly as it was presented in a clean and neat manner. Both Bill and Brandon treated my home as if it were their own and I will definitely seek to work with them again in the future. Candidly, I had another in-home consultation conducted by one of the big box retailers to help with this project prior to looking to Home Advisor, but I was so disappointed with that experience that I'm glad that I was paired up with NexImage Inc. If you are looking for service professionals that will get it right the first time, look no further than NexImage Inc. Thank you again Bill and Brandon!"

Home Security Systems questions, answered by experts

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

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. 

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

It is possible to spend only $30 on a camera that can cover one particular area. You wouldn't need to buy software, hardware, cables, or anything else. Instead, it would connect wirelessly to an app on your phone where you could monitor the feed and take necessary actions at your own discretion.

The best type of deadbolt depends on your specific needs. If accessibility is your primary concern, a single-cylinder deadbolt is the easiest to operate. Mortise locks are likely the most secure type of deadbolt you can install, but single-cylinders combined with secondary locking mechanisms like vertical locks are also a great option. Smart locks will give you the most flexibility to open and close your locks whenever and wherever you need to.
