Choosing a Home Security System Installer in Dennis

Choosing the home security system that works best for you can seem like a daunting task but taking a few moments to assess your needs will make the decision much easier.

Rent vs. Own

Whether you rent or own will influence which home security system is right for you. Renters will want to consider systems that won’t cause any permanent damage to walls since you will likely have to either make repairs yourself or lose some of your deposit when you leave. This will also make it easier to bring your equipment with you when you decide to relocate. Another consideration for renters will be whether the landlord permits affixing security cameras to the exterior of the structure and if it can surveil common areas (e.g., apartment hallways, carports, etc.). We recommend you review your lease agreement and consult with your landlord before installing any home security system component on the exterior of a rental.

Homeowners have a little more leeway when choosing a home security system since they can attach permanent fixtures like surveillance cameras and smart locks, and they typically won’t move as often as renters. However, a greater number of potential configurations makes choosing the best home security system company even more challenging, which is why it’s important to assess your needs.

Family and Visitors in the Home

Another consideration is who lives in the residence and how many people you allow access to the home. Renters with roommates may only need a security camera for their room, whereas a homeowner may want full interior coverage. If you have kids that let themselves in after school, a doorbell camera can let you know they made it home safe. If you have caregivers or others who you allow periodic access to the home, then a smart lock with customizable codes is perfect for monitoring who is accessing the house. And of course, motion sensors and interior security cameras can let you keep an eye on those furry family members while you’re away.

Professional Installation vs. Do-It-Yourself

For smaller projects, like a single camera or smart lock installation, you may want to do it yourself if you’ve got the tools and are somewhat handy. For anything bigger or more complex, professional home security system installation is the way to go. Considering the time it’ll take you to install it yourself – not to mention the headache – any money spent on installation will be well worth it. And if you choose Vivint, installation is free.

More importantly, a professional will ensure your home doesn't have any blind-spots or weaknesses in coverage. From glass-break sensors to pet-immune motion sensors, the more layers of detection the better. If you have pets, pros like you'll find at ADT are what we recommend to most people.

How Important are Smart Home Features for protecting your Dennis home?

It’s easy to forget that home security systems don’t begin and end with just door and window sensing. When choosing a security system for you home, some companies like Vivint have nearly endless automation options. We feel that preventing break-ins with smart home features like light automation and doorbell camera is the way to go.

Easy to Use Mobile App

Having an intuitive app that controls your home security devices from a smartphone or tablet allows you to get the most out of your investment.

How Smart Home Automation Can Prevent Crimes

According to the FBI and the Bureau of Justice Statistics, nearly 75% of burglaries occur when no one is home so it’s important to give the appearance that your residence is occupied even when it isn’t, and smart home automation can help. Automatically turning your interior and exterior lights on and off to give the appearance of being occupied is one of the key features of smart home automation, especially when you’re on vacation.

Additionally, smart door locks and automated garage door systems, like MyQ, can not only alert you when they are opened, but also answer those nagging questions while you’re away like “Did I forget to close the garage door?” or “Did the kids lock the front door when they left?”
