Wiring of the first camera
Andrew C.

I came to Daniel with the intent of purchasing a store box system (Lorex) and have him install it. He quickly impressed me with his knowledge of home security surveillance systems and highly recommended a system that he uses on his own home. In addition, he was able to show me the clarity of the footage even at night. I was immediately sold. Daniel was also very responsive and kept me updated every part of the step (even if he was running 5 min. late). As a home owner, I've learned that water is not my friend and Daniel shared the same view. He proactively pointed out areas where he thought would be a risk of water intrusion and mitigated that during the install. I will say that the NVR system is not for the technically challenged. It's very powerful in what it can do, which takes a lot of initial setup time. However, Daniel was able to help setup exactly what I needed. If he couldn't figure it out, we worked with the vendor to get the system completely dialed in. He did not stop until I was happy with my settings. I'm very satisfied with my install but most importantly feel much safer with "big brother" watching over. I would recommend Daniel to any of my friends and family.

Typical clean install

First of all I can't believe I considered doing this myself; the price Daniel came up with was worth it just not to spend a day in the attic. I spent a good amount of time finding an experienced installer willing to do a suite of POE security cameras on my house that I not only provided, but had strong opinions about as well as a few other network tidy up jobs. Daniel and DF Rack-n-Stack stood out in particular at first from the follow up questions; how tall is the house? what materials? what kind of access? as well as particular concern given to pest and moisture intrusion -- all of which are definitely something that should concern you if you're cutting holes in a perfectly good house. On install day Daniel showed up, attacked the problem, provided valuable insight, endless adjustments and some pretty decent company. I'm very happy I went with them and I'd recommend them to anyone.

See all

Holland Electric  - New GFCI Circuit Installation for Hot Tub Spa

Holland Electric did an amazing job installing my Ubiquiti UniFi network and running four shielded…read moreCat6A cables from my garage rack to the rooms, office, and ceiling access points. They also added a wired connection for my Mac mini so I could take full advantage of the NAS in my rack. What impressed me most was the cable routing. Getting cables from the garage up to the second-floor rooms and ceilings was no small job, but Holland managed it with only a couple of small drywall openings. The ceiling-mounted access points look clean and unobtrusive, and he avoided turning the house into a big construction project. Holland, the owner, is a Ubiquiti enthusiast and uses the system in his own home. He knows it inside and out, and that experience really showed. The results are fantastic: I'm getting around 1.2 Gbps over Wi-Fi on my iPhone and 9.4 Gbps over the wired network on my Mac mini. Accessing my NAS is incredibly fast now. Highly recommend Holland Electric if you're looking for someone who understands home networking and can handle a challenging cable installation with care!

His pricing was very transparent and he did a lot of leg work scoping out the project through photos and questions upfront which I really appreciated. He took time to explain to me the difference between outlet types needed given proximity to water which was very educational to me. He also immediately was able to identify the issue with some buzzing lights and explained that it was likely that the bulbs were incandescent not LED which was indeed the issue and I was able to fix it myself. Overall super happy with everything and would definitely recommend him to anyone and will definitely hire again for any more electrical work in future!

Xfinity kept telling me the "new" box was going to easily pump wifi through my whole house. It never worked and we had multiple dead spots in our house, where wifi never reached. We ended up trying several things, included a second network setup using Google Nest routers. That also didn't work great and we suffered for years. So finally got fed up, and I called BATH and told Ari what the issue was. He gave me a budget, which I bristled at, at first. Then he walked me through a likely fix, which involved a couple routers networked so that I had independent wifi running on both floors of the house but on the same network. The tech came by and was super nice, and walked me through what they were going to do. I was cautiously optimistic. When they were done? I almost cried at how well everything ran through my house. They even set me up so I had ethernet directly to my gaming PC, and direct into my TV and Xbox. I have not had a single issue since (beside Comcast caused outages), and have blazing fast wifi throughout the house (I pay for the gigaspeed Xfinity). I'm finally utilizing the speed as sold to me by Xfinity. Thanks so much BATH. I really appreciate it. I was super impressed with the emails, the invoices, techs being on time, and just the overall professionalism. It was worth the extra few bucks.

I came across First Reflection AV on Yelp as I was researching businesses that could not only…read moreconfigure an AV system but could do one with in-ceiling speakers and hidden wiring. I just purchased a single family home with an open floor plan and a living room area that wasn't huge, so having any kind of exposed wiring was not an option and I didn't want to devote any floor space to speakers or speaker stands. I am also an audiophile so a fully wireless setup was not going to work for me. To top it all off my house was newly renovated and the walls recently painted so I had concerns about how many holes would have to be punched into my ceilings and walls in order to wire up the whole system. Enter Ron and his associate Joel. Ron was super responsive and after an initial consultation he put together a thorough, itemized, estimate that included his recommendations on equipment including speakers, controller, cabling (cables do matter!) and ultimately an upgraded A/V receiver. It wasn't cheap, but it was fair and in line with expectations. As for my concerns about lots of extraneous holes? I didn't need to worry. Joel deftly ran a CAT cable from the router in my office on one side of the house underneath my house all the way to the living room on the other side of the house, drilling only one small hole in the office floor and making one opening in the living room wall. Joel then leveraged that opening to skillfully run speaker wire up the wall to the ceiling where he needed to make only two additional openings (one in the wall and one in the ceiling) to run ALL the wiring necessary for 5 speakers in the ceiling for 5.1 channel audio plus 2 more speakers across the room for two channel audio in the kitchen. Only three extraneous openings for 7 in-ceiling speakers? Oh did I mention it was done in just two days?! Remarkable! As Ron had promised, they fitted and screwed the drywall pieces back into place perfectly to make it super easy for the painters to mud, sand and paint over it. You can't even tell where those holes were now. Another promise Ron made was that this system would produce the best sound quality I had ever experienced and he was right. I even prefer it to movie theater sound and Ron hasn't even calibrated my system yet (I wanted to wait for my new couch and to put down my rug since I knew that would affect the calibration process). The sound is rich, full and balanced. Not too bright sounding and not at all boomy (boomy bass is NOT an indication of good quality sound). Do not hesitate to use First Reflection AV! The investment is so worthwhile and I am BEYOND happy with the final result. I've included pictures as well (holiday decorations, dog and all).

I knew the network hardware I wanted (Ubiquiti/Unifi) but needed a professional to run & terminate the wiring and install the hardware. I got quotes from 4 local companies and WizTec's was among the most competitive. They came to my home and walked the site with me, discussing my plans and offering excellent suggestions. I decided to purchase all of the networking hardware myself (rack, router, switch, cameras, UPS, etc.) while WizTec supplied the labor, wiring, and all of the termination hardware. As part of the project, I also asked them to clean up my existing coax runs and bring them back to the rack in case I ever need them in the future. After I selected WizTec, we exchanged numerous emails clarifying details about the project, recommending camera models and locations, AP locations, etc. They were extremely patient, answering all my questions and helping me to source the hardware for the project. When the install day came, they were on time and extremely respectful of my home. They worked very hard to get all of the camera runs within the walls of my house--one of the crew spent most of the day in our crawlspace pulling cable to the four corners of the house. They managed to install all of the cameras directly on the exterior walls without resorting to conduit, something I figured would be a challenge. They made minimal and very tidy cuts to our interior drywall in a few places, and repaired all of the cuts expertly (to be clear, WizTec replaced and secured the drywall pieces they cut--I had our sheetrock guy come behind them and finish the repair/resurfacing, and I'll paint it myself). They terminated all the runs cleanly and tested everything. Throughout the process they were extremely polite and communicative, checking in with me numerous times when they had questions about how I wanted something handled. It took them two days, but all of our cameras are installed, APs are live, and ethernet runs are in place. Everything comes back to a rack that is extremely tidy, with everything labeled and extra wiring on both ends of all the runs in case we need to move things in the future. I couldn't be happier with WizTec's work or the finished project.

He fully understood my situation and grasped the entire NVR ecosystem more fluently than all the others, and he has an excellent memory too! On top of that, I feel that Mike truly cares about his clients- he's not in the business only to make money, but rather to make a truly positive impact in his clients' lives. The actual installation went smoothly and it feels so much better knowing that my whole house is now covered both inside and out at every angle with 24/7 continuous surveillance. Having that peace of mind is priceless and I'm so thankful to Mike and the Suntech team for it!
