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.

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: Are keyless door locks safe to use?

• <div><p>In general, keyless door locks are considered safe, and their security depends on the type and quality of the lock. They cannot be picked like a traditional lock and often include added features like biometric access, PIN codes, and smartphone connectivity, which can make them more secure. However, they are not without risks. Potential vulnerabilities include hacking for Wi-Fi-connected models, battery failure, power outages, and technical malfunctions. To maximize security, it is important to choose a reliable brand, stay on top of software updates, and perform regular maintenance. While the risks are different, keyless locks are not considered more dangerous than traditional locks.</p></div>

Q: What is the least amount of money I could spend and still install a basic camera system?

• <div><p>It is possible to spend only <b>$30</b> on a camera that can cover one particular area. You wouldn't need to buy software, hardware, cables, or anything else. Instead, it would connect wirelessly to an app on your phone where you could monitor the feed and take necessary actions at your own discretion. </p></div>

"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."

"They system was installed for the basic, but anything that you wanted needed to be higher upgraded require alot of extra money for every upgrade.
The 36.99 monthly fee was for only if your system is connected to a landline. I didnnt notice that they charge me $44.99 until my 1st month fee. Thats when I was told that they charge $44.99 because the alram was connected to my cable line instead. I was unaware of the different charges. When tec came out he didnt show up to fix the corrected. Had to call the main company for the no show. So they schedule another appointment and offered 2 window alarms to fix the correction but my bill still is $44.99. Default is that since I didnt have extra money to upgrade to the Pulse, you dont know if you turn the alarm to your house properly. I called the 800 number and they cant tell either!
