Recently, I hired N&D Security for a security system installation, and the experience exceeded my…read moreexpectations for several reasons beyond their excellent reviews. First, the company responded quickly and professionally with clear, factual information. More importantly, I left they genuinely prioritized the customer's interests. Unlike some larger companies such as ADT, they were willing to work with and upgrade my existing system rather than push for a completely new installation. As a result, I was able to reuse most of the existing wiring, which significantly reduced the overall project cost - nearly cutting some competing estimates in half. The positive first impression carried out throughout the entire project. Both, the technicians and the owner were polite, responsive, and professional from start to finish. There were no gimmicks, hidden cost, or surprises = just quality work delivered exactly as promised.

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.

Two months, no service turned off. We had moved to new place. We call back, we need proof. We did this already, but they say they don't have it but offer two months free hoping our buyer if home would want it. we say okay but if at the end of two months house hasn't sold, cancel. They did not and drafted out our account. We call back, same mess different day. We submit documentation and forward previous emails. Time went by, they tried to draft again but we removed auto draft. Sent bill with late fee. Get on phone again and here we are trying to cancel since September 2025, it's mid April 2026, still not cancelled and they refuse to give us the months back they drafted and saying they have no record of verifying our payoff of equipment or cancellation. So I will never recommend them ever because cancelling isn't option. Seeking legal action now. We have names of cancelling department, emails and proof of payoff. Do not use them.

This annoys us, as it goes off even when bugs fly by, and it's very loud. My husband called to see about the cost of setting up service to use the system and turn off the whistle noise, but as soon as we decided the cost was too high and said no, it was like a switch was flipped in the representative's customer service. My husband asked him if there was any way to get into the panel to turn the whistle off, and Jake (the representative on the phone) said--in the most condescending tone that really took me aback--"Well, no. That's what you pay for service for." Imagine the tone you'd use if you thought someone was the biggest idiot in the world, and you'd have his tone. I've worked in customer service, and it's something I care about. This guy, Jake? He doesn't have it. By the way, he had no interest in helping or staying on the phone to answer any questions. Once we said no to service, he was done. (My husband had even said we might consider activating at a later time. Definitely not, now.) He mumbled something about transferring to customer service, didn't say, "have a good day," or anything...just left. Anyway, still stuck with the annoying whistle. Great. This wasn't a particular location, just over the phone.
