Home Security Systems questions, answered by experts

The main difference between different security sensor options is the type of motion each detects. A motion detector monitors obvious movements in hallways, entrances, and exits. On the other hand, a presence detector is more sensitive and captures smaller moves. A window sensor typically focuses on the opening and closing of the window, whereas a glass break sensor alarms you when a glass is broken.

While a strong conventional deadbolt offers enough security for most homeowners, if you’re looking for extra features beyond just simple locking, smart deadbolts are the way to go. Smart deadbolts allow for keyless entry using your phone or a code, remote access in case someone is locked out, and features like temporary access codes, automatic locking, tamper alerts and entry-exit monitoring. Smart deadbolts also come with downsides: they rely on batteries and wireless networks and are potentially vulnerable to hacking by skilled home intruders.

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, keyless locks can be quite safe, but their security depends on the type and quality of the lock you choose. Many keyless locks offer added features like biometric access, PIN codes, and smartphone connectivity, making them potentially more secure than traditional locks. However, keyless locks can also be susceptible to hacking, battery failure, or technical malfunctions, so it's important to choose a reliable brand and stay on top of software updates and maintenance.

This is the topic of much debate, though there is no “better,” as it depends on personal preferences. Some of the components of a wireless system keep working when the power goes out, as they are battery-powered. On the other hand, a wireless system typically connects to your modem and router. Wired systems use landlines to communicate, which never go out on their own unless they’re physically cut.
