Hello My Name is Rudy, For many years I worked for a contractor. I am now taking the opportunity to start working utilizing the knowledge that I have gained over the years. I know how to do plumbing, I can do electrical work and tile work. Additionally I can also do any kind of remodeling or repairs as a handy person.

Home Security Systems questions, answered by experts

When deciding whether a home automation system is right for you, consider the advantages and disadvantages first.

Pros

  • Home automation can help make your home more energy efficient, possibly lowering utility bills.

  • A wide range of automated solutions is available to meet your needs.

  • Centralized and remote control of different home automation systems.

Cons

  • Home automation can be costly.

  • Not all automated systems are compatible with each other.

  • Over-dependence on home automation can be problematic if systems cannot connect to the cloud.

You don’t need to completely revamp your security system constantly, but it’s a great idea to give it a once-over every year. Look for potential upgrades or new features—like smart home tech or replacing outdated equipment—that could boost your safety. If you make any significant changes, let your insurer know as they may adjust your discounts to reflect your improved security. Staying on top of your security not only keeps your home safe but ensures you’re getting the best possible rate on your insurance.

A potential weak link in any security system is poor connection strength or dropped signals, particularly in the case of a fully wireless system. You also want to ensure a reliable connection to get a hold of your service provider quickly. Also, you should exercise caution when handing out sign-in credentials to people outside the household.

The most secure lock for a front door is typically a deadbolt. There are many types of deadbolts to choose from, the most basic of which is the standard single-cylinder deadbolt. This is the lock you find installed on most front doors. For added security, you could go with a double-cylinder deadbolt, which requires a key to operate the lock from both the outside and the inside. 

Yes, you should always change your locks after buying a house. Do so as soon as possible after you move in. Otherwise, you won’t know who has working keys to the property, whether they’re spare keys or otherwise. If an intruder gains access to your house with a key, it may not be covered under your homeowners insurance.
