We have service centers nationwide that can install an ADT home security system within 24 hours in most areas.

All of our installation technicians are internal employees, and not third-party contractors.

"The alarm, when it goes off, is very loud!!! This is a good thing. If we ever need to activate it, it will definitely scare off anyone trying to come into our home. We can set it off from our phone or from the keyboard control panel that we installed in our bedroom. We feel very safe with this purchase."

"I’ve had nothing but problems with SafeStreets. The installation was a mess—took hours longer than promised, and the technician seemed clueless about the system. When I called customer service, they were rude and unhelpful. The security system itself is glitchy and keeps going offline. Definitely not worth the hassle."

We started in 1976, to provide quality and assurance to always satisfy the customer. We guarantee all of our work, and our employees deliver this proud craftsmanship. We also offer 24 hour emergency service. With a live answering service to take your calls, we have owners and electricians that are on standby around the clock.

"I really wanted to have a good experience with Reinhold. We’ve used them in the past and they did good work, we thought… recently our garage’s power stopped working, which is fed by a panel on the pole that they installed in August of 2022. We NEVER had a single electrical issue until after that pole was installed which is starting to make sense. A few months ago we began having electrical issues in our house, so we called Reinhold because we thought they did a good job when installing the pole that fell in 2022. The technicians that were out to see what the cause of the electrical issues in the house were said that the lines under ground were corroded (which may have been true), so we accepted to let them fix it. They hand dug by the electric pole, buried conduit and ran new wire to the house and everything seemed to be fine until we recently started having issues with the electric in our garage. The location where they dug and buried the conduit for the wire going to the house is in a very close location to where the conduit goes for the wires going from the pole to the garage. I called for an estimate and was told $5,000 worse case scenario which may be understandable considering that would include cutting asphalt, trenching, new conduit, new wire and labor so I get that. Upon receiving this news I decided to just take care of it myself. I went to the building department for our county to take the test to do residential electric work, paid for the permit to be pulled, had everything cleared with Missouri 811 incase I needed to dig and bought $700 worth of new wire. I pulled the old wire, saw that there was a break in the wire due to corrosion from water getting in the conduit underground so I started digging right where the conduit meets the pole that Reinhold installed just to see if there was a break in the conduit. Sure enough, there’s a small section of conduit that was crudely placed over where the old conduit underground is and the new conduit where they installed the pole. They had it lightly wrapped in what looks like some kind of landscape fabric (thought it was electrical tape at first). So there was no protection in the conduit against water getting in which was what caused the wire to corrode to the point of no longer working. Mind you, Reinhold is THE ONLY company we’ve had at our house for electrical work since owning the house. When I saw this piece of conduit being very improperly “connected”, I took pictures, and videos and sent them to the estimator who came out to give me a quote for fixing the electrical issue in the garage. He said he would give me a call back after speaking with the technicians that were there more recently to fix the electrical issue with the house as well as the ones who installed the pole in August of 2022. After speaking with them he said that none of them claimed to do that and that their technicians would never do something like that and all these denials of my claim. He then told me that he could come out and fix it for $500-$600 FOR A 3” LONG SECTION OF CONDUIT THAT NEEDED TO BE REPAIRED FROM THEIR PREVIOUS WORK. I am not the type to ask for free stuff from ANYONE, I’m incredibly happy to pay for good service by good people and I thought that’s what we were doing with Reinhold until yesterday. They completely denied the fact that their technicians made a mistake, and didn’t offer to fix the issue or anything. I was told that all of the technicians that have been on our property did not do it and that it would be $500-$600 to fix something they installed incorrectly. I understand if a technician didn’t remember every little detail from a job they did in 2022, but there is no integrity or accountability on their part with this issue. It was either done in 2022 when the new pole was installed or a few months ago when the new wire was put in with new conduit by REINHOLD."

Home Security Systems questions, answered by experts

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.

A study from the University of North Carolina found that security system signs 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’s best only to put up signs when you have the alarms to back them up.

Security cameras do not need wiring if they are wireless, meaning they are battery-operated and can connect through Wi-Fi. You’ll need to change the batteries on a wireless camera and ensure you have a steady connection to Wi-Fi for video storage. If you have a wired security camera, you’ll need to plug it into an outlet or other power source and a DVR device.

Options include wired or wireless systems with night vision and motion detection.

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.
