"Bryan D helped me with my new house alarm. Bryan was friendly and pleasant to work with. He took his time and listened to my needs for my desired level of security. (I am quite the paranoid person when it comes to home security!) He is extremely knowledgeable and was informative and thorough on all aspects of security, from the system functionality to do-it-yourself enhancements around my home. He gave me a ton of great advice and I feel 110% at ease with my security system! I highly recommend you work with Bryan at Alarm protect group!!"

"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 questions, answered by experts

Yes, it’s possible a burglar can get through a deadbolt. Some types of deadbolts are harder for an intruder to get through, though. For example, a single-cylinder lock only requires breaking a window nearby and simply turning it. While other locks, such as a double-cylinder lock, may offer greater protection and make it harder for an intruder, no deadbolt is 100 percent effective.

Insurance companies weigh the amount of potential liabilities on your property to increase (or decrease) the cost of your home insurance. They will use several factors to decide if there are more chances for peril or injury to take place at your home. These factors include your location (whether you live in an area with high risk for natural disasters), the age and condition of your home, and whether you have any “attractive nuisances”—features that both increase the aesthetic of your home and potential for injury—like a pool or treehouse. 

The best window alarm sensor depends on the type of window you’re concerned about since different types of sensors will work best in different scenarios. Many homes are equipped with contact sensors, which trigger an alarm when a window is opened, and each part of the sensor breaks contact with the other. But there are other options, too, like a glass break sensor or motion sensor, which both work well for windows that are in low-traffic areas.

To prevent false alarms, motion detectors need proper placement and settings. Start by installing them away from pets and windows where outside movement could set them off. Adjust the sensitivity settings to reduce the likelihood of it detecting minor motions. Consider using dual-tech sensors, for example passive infrared (PIR) and microwave technology, to improve accuracy and reduce false alarms. And don’t forget regular maintenance—cleaning the sensor and checking for any obstructions can go a long way in making sure your detectors run smoothly.

Instead of a security door, you might opt for a heavy-duty screen door made from durable mesh, which allows better sunlight and airflow. Additionally, you could enhance security by installing strong locks on your existing door. A double-cylinder deadbolt provides robust security; however, be aware that some local laws prohibit them due to safety concerns during emergencies.
