5 of 5 Quality Equipment Backed by Amazing Support! April 17, 2024
Reviewer: Mary B from Roseville, California  
Ordering a new security system was easy because I knew I was going to order from CCTV Camera Pros. I’d dealt with them years ago when setting up a much cheaper, simpler system. Over the years, I followed CCTV Camera Pros on their website and received regular email updates regarding new technology. I’m not remotely knowledgable about CCTV and the intricacies of the cameras, DVR’s, and NVR’s. Talking to Mike assured me that I could get exactly what was needed for my situation and feel comfortable using it. I knew I wanted complete coverage of the property, AI cameras, and an LPR camera. I sent Mike pictures and he showed me exactly where each camera should be placed for optimal coverage. Whenever I had questions regarding specifics of each camera or NVR set-up, the professionals at CCTV Camera Pros have always walked me through it with incredible patience and support. I’ve never felt like any question was a “dumb question”. These guys know what they’re talking about and they live and breathe this technology! I should also mention the care and speed of shipping. All equipment was packed well, arrived quickly, and was tracked throughout the shipment. I also found the return of some unused junction boxes to be smooth and easy. If you’re in need of quality cameras specific to your situation, CCTV Camera Pros provide the very best service and technical support I’ve ever experienced…..and they are a Veteran-owned company…..a definite plus!!

5 of 5 Top Rated Video Surveillance Products! March 26, 2024
Reviewer: CS from Newport News, VA  
CCTV Camera Pros will be my go-to for video surveillance and security peace of mind. I purchased a video system for my home December 2023. I had an opportunity to use and assess the customer service, reliability and functionality of the system. As of today, of writing this review, CCTV Camera Pros staff Mike, Greg and Carlos are amazing. You will be talking with real people and not waiting on the telephone for hours. The customer service response time is immediate feedback to resolve any issues or questions. Stop wasting time searching for weeks and months on google and YouTube for the best system. This is your one stop shop with experts in the field to meet your every need. Lastly, I had six incidents in the last two months of people who entered my video surveillance zone with 100% deterrence. Based on my experience with other companies such as Ring and Vivint; there’s no comparison regarding customer service dependability, remote access and playback speed. Stop procrastinating and invest with CCTV Camera Pros, you will not regret it!

5 of 5 Not only AMAZING equipment, but SUPERIOR long-term January 17, 2024
Reviewer: Carl S from Springfield, MA  
I needed affordable, modern-day advanced or AI Camera technology for a custom project that included License Plate Reading (LPR), Vehicle Detection, Face Recognition, Tripwire/Intrusion Zones, and Alarm Signal Output. I knew the technology existed and that integration was possible, but I didn't know where to find it until I found CCTV Camera Pros.

The Viewtron NVR AI system completely exceeded my expectations and in my opinion is well worth every penny.

The documentation, videos, and walkthroughs available directly from their website made setup and configuration and absolute breeze. While I didn't have any problems, I had some questions to clarify and was more than happy with their response time, clarity, and guidance.

As I moved to optimize my system, I needed some help and they did not hesitate to respond and help above and beyond what I would say you typically find these days from other companies. They CONTINUE to blow me away with how they do business and fully embrace the customer relationship. It is clear that the CCTV Camera Pros team take pride in what they do and *WANT* to teach people how to be better.

CCTV Camera Pros will continue to be my very first go-to for any new project!

5 of 5 Plug and Play Heaven July 13, 2023
Reviewer: Chrys R from Surfside, California  
I needed a new camera system for our parking garage that I could install myself. After many months of research, we pulled the trigger and bought a 4K 16 camera all-in-one system from CCTV Camera pros. The NAT option, so I could see the cameras remotely online, was what sold me, and it worked seamlessly. The picture quality is great. My title of plug and play is how I feel about how easy this system was to install for me. Shipping was fast and all the online info made this a great experience. I highly recommend this company!
