You might like to know that you’re buying the right equipment and getting it at a fair price. **WE SPECIALIZE IN HOME STEREO AND THEATRE SYSTEMS**There's a proven way to do that - good planning. With 20 years professional experience I know what to ask you whether you’re an avid enthusiast or a novice. I know what to look for in your home (i.e. infrastructure). And, we talk. After we're done planning, you've got one very solid solution. (And, this is what I love doing!) A manufacturer-authorized dealer, you pay no more for product bought through me than you would from a brick-and-mortar store. You benefit from my lack of overhead expense - mine is a home-office - by paying less for installation. You get my support after the sale so you don’t have to deal with frustrating tech-support lines. DH Audio and Home Theater offers wired and wireless speakers, TVs, home theaters, acoustic room treatments, equipment cabinets, and Wifi-Network systems.

"Dennis was very professional and comprehensive. He was prompt and paid attention to our individual needs. He made sure that everything was working properly and that we were comfortable using all the equipment. I would strongly recommend his services."

Smoke Detector Installers questions, answered by experts

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

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.

While security hubs can streamline the management of security cameras, the placement of cameras itself is often determined by factors like your property layout, security objectives, and areas of concern.

Grounding is a great first step to prevent electrical shock, but you can take it further with GFCI outlets and AFCIs (arc fault circuit interrupters). In particular, AFCIs help protect against the type of electrical arcs that cause fires, like if a mouse chews on a wire or your laptop starts overheating at the wall. These are required in some areas of your home.

Yes, a DIY security system can qualify for home insurance discounts, as long as it includes key features like cameras, motion detectors, or alarms that effectively deter break-ins. While insurers often lean towards professionally monitored systems, they generally value any proactive measures you take to boost your home’s security. Just make sure your system is properly installed, and keep your insurer in the loop about its features and any monitoring systems you’ve set up.
