5 of 5 Great Product and Service June 20, 2024
Reviewer: Andy H from Philadelphia, PA  
I was looking for a camera to read/record license plates but wasn't really sure what to get. I found CCTV Pros online and the reviews were good so I checked them out.

Website contain LOTS of useful info, tech details, and videos that walked me through everything. Still it's a pretty big investment so I reached out with some specific questions. I got an immediate response from James who sent back annotated photos of my layout, explained how to set things up, and assured me that I had the right camera and that it would work with my set-up. I took the plunge. Because I was using a standalone camera networked directly to my PC (not to an NVR) things were a little trickier than I anticipated.

Again I reached out to James directly and he responded (patiently) to all of my questions. Long story short if not for the amazing customer service I received both before and after the sale I likely would not have this system now.

Really grateful for all the help - I've been up and running now for about a month and couldn't be more satisfied. Also nice bonus to support a vet-owned business!

5 of 5 A lot of features in Viewtron products May 29, 2024
Reviewer: Perry C from Norfolk, VA  
CCTV Camera Pros have an impressive line of NVRs and Cameras that integrate seamlessly. I have worked in IT for the past 20+ years and I like to tinker. I chose CCTV Camera Pros and their Viewtron line because I did not want a system that would be dependent on internet or cloud connectivity. This system is happy working standalone. That said, you can configure your network and NVR to allow remote login/management from the internet.

I have contacted their support several times for various things such as : "explain x,y,z feature", "how-do-I do or can I do something", "will this off-brand camera work", or "how can I reset my lost admin password?", "Is there a firmware upgrade". Their support staff are CCTV Camera Pros employees and everyone I have chatted with have been courteous and knowledgeable about their products. They've had the answers and walked me through whatever the issue was. I cannot ask for more! Their Viewtron cameras are well-built and awesome as well. They have a Viewtron for nearly every scene that you would want to surveil and have installed a variety of the different models. Currently I am running 10 cameras - (3) A4BZ, (3) A4D, (1) A8D Viewtron cameras and 3 off-brand POE IP cameras. The off-brand ONVIF compatible ones do not have the AI features of the viewtrons but many of the features of the NVR work with them including PTZ/Zoom/recording schedules etc. I can say that the off-brand ones are certainly not the same build quality or as feature rich as the Viewtron ones.

Overall, I am very pleased with the Viewtron NVR and Cameras, but I am delighted by the people that are a part of CCTV Camera Pros!

5 of 5 Excellent Product May 23, 2024
Reviewer: Joshua T from Columbia, New Jersey  
The LPR camera paired with the suggested NVR handled our needs perfectly. Yes, it costs more than a bargain system on amazon but you really do get what you pay for with this.

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 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!
