"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."

ACB Services are full service Spring Branch, TX Home Remodelers who take pride in a job well done. We settle for nothing but the best in order to deliver unbeatable service.

"I clearly had my project under the section ?Mount TV on wall?. I clearly stated on the listing that I needed a 65 inch tv MOUNTED on my wall with a tilt/swivel mount and an in wall tv power kit. The guy shows up an hour late, which I completely understood being the day before Thanksgiving, only to come in my house and act like he didn?t know the project was for mounting my tv. He said he thought it was just for the in wall power kit. Then he said he would do me a favor and charge me $100 more to mount the tv with the full motion mount, after quoting me $195 plus 4% fee for using a debit/credit card, bringing it up to over $300. I told him to get out of my house. He sends an email that states their business is of Christian brothers. I wonder if he understands that God doesn?t let people get away with deceptive practices, especially when using His name: Acts 5:3?5. Hopefully, this guy and his partners change their ways before it?s too late. Praying for those cheats! In Jesus? Name!"

Home Security Systems questions, answered by experts

Wireless cameras will not work without an internet connection. A Wi-Fi camera uses the internet to transmit footage and store the information in cloud-based software. However, there are wireless cameras that you can buy that allow you to record and save footage on an SD card instead.

Professionals optimize camera placement, integrate recording systems, and ensure tamper-proof security.

A security camera company will be able to advise you on where to position the cameras, ensure all of the equipment is set up properly, and do all of the installations. They’ll take factors into consideration that a non-professional might not automatically consider, like obstacles that could block a potential trespasser from the camera or how lighting may obstruct the view.

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.

Costs depend on system type, labor rates, and additional features like smart integration or professional monitoring.
