Q: Can you reset a house alarm without a code?

• <div><p>You likely can reset your house alarm without the code, but it depends on many factors like how it&rsquo;s wired and whether or not there&rsquo;s a default reset code. Most companies make bypassing a security alarm without entering your code challenging to prevent burglars from simply resetting the alarm during a break-in. Your best bet is to contact your alarm company directly to get specialized support for your situation. </p><p>But, while you wait for support, you can disconnect it from the power source to stop the alarm from going off.</p></div>

Q: Can security cameras work without Wi-Fi or an internet connection?

• <div><p>While many security cameras rely on an internet connection to transmit footage and store it in the cloud, not all of them stop working when the Wi-Fi is off. Some models are designed to function offline by using local storage options, such as a microSD card or a network-attached storage (NAS) device. These cameras can continue to record footage even without an internet connection. You can then access the stored data once the Wi-Fi is restored.</p></div>

Q: Do alarm system signs deter burglars?

• <div><p>A study from the University of North Carolina found that <a href="https://www.angi.com/articles/do-security-signs-and-decals-stop-thieves.htm">security system signs</a> were one of the top ten deterrents for burglars when choosing a target, so they do have some effect. However, you can get into legal trouble for putting up fake signage, so it&rsquo;s best only to put up signs when you have the alarms to back them up.</p></div>

Q: What types of surveillance systems are available through pros?

• <div><p>Options include wired or wireless systems with night vision and motion detection.</p></div>

Q: What is the most secure type of lock for a house's exterior doors?

• <div><p>Security experts recommend deadbolt locks as the most secure option for a house's exterior or entry doors. Deadbolts provide the best security because they can prevent most types of forced entry and are harder to lockpick. Common types include the standard single-cylinder deadbolt, which is often found on front doors. For enhanced security, you can opt for a double-cylinder deadbolt, which requires a key to operate from both the inside and the outside.</p></div>

"It went great! From Travis the sales person to Noah the installer I couldn't have asked for a more professional and through team to deliver my home security needs. We just bought a new house in a neighborhood that's up and coming but there's still an element that we want to protect our home and valuable from. Security One helped us find a system that we could monitor while we're away and that would make my girlfriend feel safe when I'm not a home. We highly recommend them especially Travis and Noah. Ask for them by name!
