    Agreed with the comments here. Very rude. Close your business and go back to school to learn how to interact with customers,.

The people that work here really care, the owner is very responsive, could not be happier with our choice! Highly recommend!

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.

    I had no idea what to search for or what to expect when contacting a private security business…read more This was my first time seeking out these services in order to more safely address/resolve a situation with a mentally unstable, aggressive, and often-drugged up individual. I spoke with Mike on the phone last week about my situation. He was professional and patient with my little worry-filled self. He followed up diligently to my questions / concerns and provided resources that were helpful for my situation. He worked w my uncertain timeline due to this particular unstable individual's unpredictability. The situation ended up resolving peacefully. I am grateful for Mike's support throughout it, and I highly recommend working w him for your security needs - whether as a little female like me fearful and needing help; or private security for dignitaries; or for organizations needing security for events. It was difficult to figure out what to search for with private security, but through this experience, I learned through a bit of research that Virginia's Department of Criminal Justice Services (DCJS) has a website where you can look up a business related to security and see the license info (and make sure they are legit too if you're working w one private individual). You can also read into what the differences in training are for each of the certifications. Mike has agents available who can serve as unarmed and armed security with arresting authority. (There might be more security services his business does, but this was mainly what I was needing so that's what we spoke on!)

    Mike was more than accommodating and helpful with my personal situation. Professional, polite, and…read moreextremely knowledgeable. He went above and beyond with thoroughness and I could tell that this came from a sincere desire to help others in need. I could not recommend more.
