Home Security Systems questions, answered by experts

Yes, adding ease of use and remote access via smartphones.

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

Changing the alarm in your wireless security system is a perfectly reasonable DIY task that most people can complete on their own. Simply open the system’s control panel, remove the existing battery, and replace it with a new one. If you’re using a wired system, this may require disconnecting and reconnecting both the positive and negative wires attached to the battery, and you may want to call in a professional to help. 

It depends on your specific needs. A security system typically includes alarms, sensors for windows and doors , and 24/7 monitoring services, offering comprehensive protection with immediate response to potential threats. Cameras, on the other hand, primarily provide visual surveillance and evidence collection. A security system is preferable if your primary concern is deterring intruders and receiving real-time alerts. Cameras are ideal for monitoring and recording activities but might offer a different level of active protection. In many cases, a combination of both—a security system with integrated cameras—provides the most robust home security solution, offering prevention and documentation.

Home security cameras typically do not record continuously 24/7. Most options use motion detection technology to trigger recording when they sense movement or a significant change in their field of view. This approach conserves storage space and reduces the need for constant monitoring. When motion is detected, the camera starts recording and may send alerts to the homeowner. However some cameras offer the option for continuous recording, but this requires substantial storage capacity and may overwrite older footage when space runs out.
