"Great experience with nighthawk! I purchased my own security cameras and needed help installing them. The technician was super knowledgeable, professional, and worked quickly. The job was done perfectly (and I’m sure it was a challenge - we live in a super old house!!). He made it seem easy! Highly recommend and will definitely be going to them for any future needs."

"We were with another monitoring company and Lloyd Security helped us throughout the transition and even sent the cancellation request for us. They made sure that careful attention was given to the aesthetics of the installation because we did not want wires to show or have extra holes drilled. They showed up when expected and completed the job the same day as promised. It's nice to deal with a business that is not only courteous, but prompt, careful and knowledgable."

Home Security Systems questions, answered by experts

Several types of deadbolts are available, including single-cylinder, double-cylinder, rim, smart, and electronic deadbolt locks. The most common type found in U.S. homes is the single-cylinder deadbolt, which uses a key on the exterior and a thumb turn on the interior. A double-cylinder deadbolt features two locking mechanisms and requires a key to be operated from both the inside and the outside.

Yes, keyless locks can deter burglars, mostly because they boost security and offer advanced features. Most models allow for unique codes or temporary access, making it harder for intruders to break in. Many of these smart locks even alert you if someone tries to tamper with them. However, you need to remember that while they provide an added layer of protection, no lock is completely foolproof. Pairing these locks with good security habits—like proper lighting and surveillance cameras—creates a strong defense to help stop intruders in their tracks.

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.

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