Angelica L.

Absolutely love our security system! Larry was great from the initial appointment and on installation day. He explained everything he was doing and made sure to walk us through how to use our system both from the monitor and from our phone app. We got a smoke detector, carbon monoxide detector, window and door sensors, plus two outdoor cameras. The video quality is amazing, we get updates anytime the camera senses movement and we can watch from our app. On the second day of having our system I forgot to disarm it when entering the house and it set off the alarm, we got a phone call immediately making sure we were ok... then they even sent us a card! Great customer service. So happy we went with them over the other security systems available. Also, it's pretty affordable.

Absolutely love it!!!

The work was completed in a timely manner, and they did an excellent job of keeping things tidy and cleaning up after themselves when done.

From start to finish, they were professional, punctual, and clearly took pride in their work. What really set them apart from the other four companies I got quotes from was their attention to detail -- they not only ran all the cabling cleanly, but also repaired and painted the drywall afterward, leaving everything spotless. My home posed some challenges since there's no traditional attic access, but they found a smart solution by cutting a discreet access point and installing a clean, removable panel that looks like part of the original design. They even went above and beyond by installing a drop-down TV mount in my living room since my fireplace mantel sits too high for comfortable viewing. The entire experience exceeded expectations, and I wouldn't hesitate to hire Trebor Tech again or recommend them to anyone looking for quality network or low-voltage work.

From my first phone…read morecall with Sally and Perry to the installation with Darren, John, and David, the experience could not have been more seamless. Initial Communication: Before settling on N & D for my home security system, I did tons of research, including research into all the big home security companies. Unlike other companies, N & D Security does not lock you into a long-term contract, nor did they try to upsell me on products and services that were beyond the scope of my needs. Rather, Perry readily identified what would likely make sense for my home, asked incisive and poignant questions about my home security needs, and carefully listened to and thoughtfully answered all my questions. He then diligently followed up with a recommended package for my home. Perry's attention to detail, follow-up communications, and responsiveness was impeccable. And I was all the more impressed given the fact that N & D is a small team that essentially operates as a family-owned business. Installation: The installation could not have been more seamless. John, Darren, and David arrived promptly. They installed the security system and had me up and running in little to no time. I was thoroughly impressed by the service--the N & D team went above and beyond anything I could have expected. For example, in addition to setting up my home security system, Darren helped set up our doorbell camera and even attempted to help install smart locks throughout my home. Upon the immediate completion of the installation, John carefully explained how the system operates, patiently answered all my questions, and even gave me his personal number in the event I had any additional questions. After Installation: After completing the installation, Perry checked in again to ensure that all our needs were handled and that our system was up and running. In addition, the N & D team was incredibly diligent in completing additional follow up work I had requested. In sum, if you are looking for a top-notch home security system, N & D is a no brainer. They are a pleasure to work with and I can genuinely say that choosing them for our home security needs was one of the easiest decisions I've made.

I strongly advise anyone considering working with Monica Escala to look elsewhere. My experience…read morewith her has been nothing short of a nightmare, and I feel obligated to share it to prevent others from going through the same. I hired Monica in December 2024 to install: 28 security cameras A sound intercom system with 18 speakers 5 access control pads integrated with the fire alarm system As for the security cameras, she agreed to install 28 after reviewing my architectural plans but only installed 16--and did so carelessly. Wires were left hanging, ceiling tiles were damaged with large holes, and I was never given access to the security system, while she retained full access and was apparently monitoring the premises without authorization. The cameras themselves were cheap, low-quality models from Amazon (under $50 each)--completely unsuitable for a commercial setting, despite charging me for a professional setup. I paid her the full contract amount for this portion, and she has yet to complete the job or give me access to recorded footage. Despite paying her half of the contract amount upfront, she never delivered or installed a single access control pad. Even worse, she had no clue how to connect them to the fire alarm system--something that should have been fundamental to her scope of work. I had to bring in my fire alarm vendor and general contractor to explain to her how to do her own job. Still, nothing got done. Regarding the sound intercom system, she was supposed to install 18 ceiling-mounted speakers. Instead, she purchased cheap desktop speakers (less than $30 each) from Amazon, dumped them on the floor, and suggested installing wall shelves to mount them near the ceiling--completely unprofessional and unusable for a public facility. Meanwhile, she continued demanding more money and delayed my entire project by over five months--from December 2024 to May 2025--causing serious disruption and financial loss. To make matters worse, she repeatedly entered the property without my knowledge or permission, even after I explicitly told her not to. She frequently asked the building's front desk for access, showing a complete lack of respect for boundaries and professionalism. Monica Escala has shown a complete lack of expertise, ethics, and professionalism. She overpromises, underdelivers, delays critical projects, uses substandard materials, and ignores basic contractual obligations. In my experience, this was nothing short of a scam.

Reisterstown Station

It's the week of getting house stuff done before I go on vacation. So my door has been drafty,…read morecreaky, and crooked for a while, but I finally decided to get it addressed. Right after putting in an inquiry on here, I got a message and then a phone call not long after that. I scheduled for the 2-4pm time frame for someone to come and give me a free estimate, and two guys showed up at 1:53pm. I was surprised, because I was told I would get a text, but I didn't. It didn't work in their system for some reason, I saw him try in front of me. But it was a pleasant surprise, I was available! Their names were Elmer and Kingston. They assessed the door, told me what they would have to do to fix it, gave me the honest price point, and asked me whether I wanted to hold off or have it done immediately. I decide to just get it done, and so I asked them to hold on for me to secure my cats so they wouldn't run outside. They literally had to take the door off of the hinges! They used that time to go grab tools and a patiently waited for me to let them know when my cats were secured. The job didn't take that long, I didn't actually time it.... Maybe about 40 minutes? They were efficient and really did their thing. So now, my door is fixed and I'm ready to go on vacation. They aren't the closest geographically, but they do serve the entire area. Would recommend if your door is having issues!
