I can't say enough about their tech support! Tim from support was so patient and more than willing to help. We have several CCTV systems and won't buy anything else, solely due to their support! Won't find anything else like it.

Purchased their 8 camera 4K bullet system and added 2 fisheyes. All hardwired. The equipment is super easy to hook up. Everything is literally plug and play. Picture quality is superb! The cameras show good detail and great color images even at night.

Called to inquire about a 24 camera system for our church and got exactly what we needed. The wide angle cameras helped us to cover the entire property. Installation was a breeze and everyone is always amazed by the exceptional image quality. Set it up to view on my phone within 15 minutes. Works flawlessly. Highly recommend for top quality and great support.

Bought a system from CCTV. Easy to install. After a few weeks realized I needed some extras cameras. I went back in to order more. The ones I click on and purchased were not compatible with my system. A live person from CCTV called and emailed about the problem. With their help we got the right cameras shipped. Most companies I have dealt with would have shipped the order even though it was the wrong item. I appreciate the customer service CCTV has provided. Would recommend to any and all in need of their product.

Recently ordered your top featured system and received it within a few days. I am so impressed with how technology has improved. With my past systems, I used to receive so many false positive motion notifications. I really love the new smart motion alerts since it focuses specifically on humans and vehicles. I will say it has been a huge time saver. Well done!

Excellent. Spent extra time explaining how each of our needs would be met by the system they put together for us. Extremely professional and understanding when we had to call once we received our items. Highly recommend them to others.
