"Dennis and his team were very professional and walked us through the whole process of installation. He gave great product recommendations on products and cameras that were best suited for our home. The quality of the cameras is top-notch. The work was done in a timely manner, and the installation was quick with great results. We absolutely love our home surveillance system and would highly recommend North Cal Security for home or business surveillance installation."

Home Security Systems FAQs, answered by experts

Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.

Yes, many providers offer reinforced steel, fire-rated, and electronic access doors for businesses.

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. 

A security camera company will be able to advise you on where to position the cameras, ensure all of the equipment is set up properly, and do all of the installations. They’ll take factors into consideration that a non-professional might not automatically consider, like obstacles that could block a potential trespasser from the camera or how lighting may obstruct the view.

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.
