"I would not hesitate to recommend MSI to anyone needing to have security cameras or alarms installed in their home. They always arrived at the time that was specified which was 0830. On their first attempt to install the cameras it was raining profusely but they tried to install them anyway. However, at one point it became to dangerous and they had to stop and reschedule the installment. Nigel Frazier and his team are very professional and knowledgeable about the security system that they install. I'm very pleased with their professionalism and reliability."

"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

Smart deadbolts are a worthwhile investment for homeowners seeking more convenience, flexibility, and advanced features than a traditional deadbolt can provide. While a strong conventional deadbolt offers sufficient security for most, smart deadbolts provide significant upgrades.

Key benefits include keyless entry via smartphone, keypads, or biometric sensors, and the ability to lock or unlock your door remotely. You can also manage access for guests by creating temporary codes, eliminating the need for physical keys and the risk of them being lost or duplicated. Many models integrate with smart home systems and offer features like automatic locking, entry-exit monitoring, and tamper alerts with encryption for enhanced security.

However, there are downsides to consider. Smart deadbolts are more expensive than their traditional counterparts and rely on batteries and wireless networks to function. This dependency introduces potential vulnerabilities, such as hacking by skilled intruders and privacy concerns. Installation can also be more complex. Despite these drawbacks, the added layer of convenience and protection makes them a compelling option for many.

Yes, there are, and they often come with a screw set to ensure they stay secure. They run on batteries, depend on WiFi, and often require a WiFi extender. These typically cost less than $50. Doorbell cameras like these are great for renters who can't install a wired solution. However, a wired doorbell camera is a better choice for homeowners looking to invest wisely in home security.

Installing a gate on your property is often a worthwhile investment, despite the initial expense. Gates enhance your home's curb appeal and can increase its property value, making them more attractive to potential homebuyers. They provide significant security benefits by keeping out unwanted guests and increasing privacy for your household. Additionally, a gate can help keep children and pets safely contained in your yard.

For driveway gates, automatic versions are particularly convenient and tend to add more value than manual ones. The choice of gate material also plays a role in both aesthetic appeal and security. Beyond driveways, side gates can improve accessibility to your rear yard, making the outdoor space more usable. Overall, whether for security, safety, or aesthetics, installing a gate is a valuable addition to a property.

Home security cameras typically do not record continuously 24/7. Most options use motion detection technology to trigger recording when they sense movement or a significant change in their field of view. This approach conserves storage space and reduces the need for constant monitoring. When motion is detected, the camera starts recording and may send alerts to the homeowner. However some cameras offer the option for continuous recording, but this requires substantial storage capacity and may overwrite older footage when space runs out.

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.
