"Showed up and spent about 90 minutes looking at the TV (which was already mounted to the wall) and talking to my husband. Said he needed a part and he had to go to Bulverde, Tx for the Home Depot (about 45 minutes away) because getting the part from the hardware store in town might be a liability. He never came back. He called a few hours later and said he had to go to San Antonio, Tx for the part. The company then tried to bill me over $600. When I protested they dropped the bill to just under $400. I have called and left messages but they will not call me back but I am getting multiple emails and text messages asking me to pay them."

Home Security Systems questions, answered by experts

Expect to spend an average of $150 to $500 to set up a home flood detection system. However, be aware that costs are wide-ranging. You might only spend a budget-friendly $50 to place basic, battery-operated sensors in a few key areas of your home, or $150 to set up two or three smart sensors. The purchase and professional installation of a whole-home protection system with water shutoff capabilities could cost between $500 and $1,000.

Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.

It is possible to spend only $30 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.

Any type of dead bolt lock provides the highest level of safety for a single device. However, it’s also important to determine a lock's grade. Locks can come in either Grade 1, Grade 2, or Grade 3, which indicates how durable it is and if it’s constructed solidly. Safety experts recommend choosing locks based on Grade 1, which offers the highest level of durability.

You should be able to use your smart doorbell and access your video feed without a subscription. Subscriptions give you special features, such as night vision, downloading, and automatically saving footage for a set amount of days. It’s a good idea to compare plans among different providers before you commit.
