"Bought security through ADT mainly for the automation options that come with the system. My spouse loves being able to turn on and off our lights in different areas of the house while we are gone. We travel often, so giving the illusion that we are home is a good deterrent."

The modern suburban and small town home of today has become an ideal lightning target. The home owner would do well to recognize lightning for the destructive force that it is and protect against this major life and fire hazard. Donohue's Lightning Rods is based in Missouri, near the factory where most of the residential and commercial lightning rod supplies are manufactured. Jim travels regularly to Texas, Louisiana, Arkansas, Missouri, Kansas, Montana, Wyoming, Colorado, and New York. Call today to find out when Jim will be in your area. For installations outside Missouri, Kansas, or Texas, Jim waits until there are a few customers lined up, thus being able to provide the same quality services at affordable prices. **WE DO NOT DO ELECTRICAL SERVICES.** (ONLY LIGHTNING RODS)

"The job was beautifully and professionally done. I have a zero scape yard and the gentleman was concerned about disturbing the gravel when putting the rod into the ground. WOW!!!!"

Smoke Detector Installers questions, answered by experts

Different beeps generally mean different things, depending on the smoke alarm model. Continuous beeps usually mean the alarm has been triggered, so treat continuous beeps like a fire until proven otherwise. Double or triple beep sequences (where it beeps two or three times with a pause in between) may be a carbon monoxide alert. Immediately open windows and doors to vent the home, and go outside for at least 10 minutes. A single beep with a long pause in between is usually a low battery warning. 

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.

Digital door locks are just one part of a whole-house security system. You can also install indoor and outdoor security cameras, door and window sensors, motion detectors, smart lighting, and smoke, fire, and CO detectors. 

Remember, every home layout is different, and landscaping and custom designs can impact which security system parts offer the best protection from crime. Speak with a professional to help you decide which combination works best for your home’s security.

Your smoke detector might be too high in some homes or circumstances to reach yourself. If you feel unsafe getting on a ladder to replace your hardwired smoke detector, call a licensed electrician or local handyman to knock this project off your to-do list. If you have a battery-operated smoke detector, your local fire department can change the batteries or help you replace the detector—just make sure you call the non-emergency number.

In any case, do not let this project go unresolved, as it could turn into a huge safety issue.

No, wired systems are not obsolete. While many people assume that wireless systems are superior, wired alarms still have their advantages, including a stable connection that doesn’t rely on wireless signals, making them less susceptible to interference or hacking. They also don’t require battery replacements, reducing maintenance concerns. Wireless systems have improved in durability and signal strength, but for those prioritizing reliability and security, a wired system is still a great choice.
