"John from Computer Controlled Security personally came to my home for a free estimate. He was honest, trustworthy, and reliable. I was able to leave him in my home to work while I was at work, and thoroughly explained how to use the system without losing patience. He is always very responsive when I have questions and worked extremely efficiently. I love my cameras and alarm system and feel highly protected. I highly recommend Computer Controlled Security."

"The worker was so honest. He tested my system and determined that a code was missing to program the new keypad. He suggested that I contact the manufacturer for that code. He showed me how to do it myself and HE DID NOT CHARGE ME FOR HIS VISIT. I would highly recommend this honest business! Thanks EZ switch!"

Home Security Systems FAQs, answered by experts

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.

Yes, it's possible for hackers to access wireless security cameras by guessing or stealing passwords. Additionally, your camera's cloud content can also be hacked. Finally, some criminals use Wi-Fi signal jammers to disable wireless cameras.

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.

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.
