"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."

Yes, driveway gates can help secure your home by deterring burglars from accessing your property. Climbing a gate slows down burglars while also attracting attention to your gate. If you live further down your property and want to increase security, you can also install a gate security camera that connects to your gate and monitors the area for suspicious activity.

Professionals optimize camera placement, integrate recording systems, and ensure tamper-proof security.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

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.

Yes, you can install a home security system in an old house. In fact, you can install a security system in any home.
