Rated 4.3 out of 5 by 26 reviewers.
Rated 5 out of 5 by Great customer support I bought this product, on-line, and when it came in, I had some questions, because the instructions are lengthly, and sometimes not clear...Quality is fair, as far a color, but you can go in, and adjust the colors, picture to suit you. I called their 800 number, on 3 different occasions, and they WALKED me thru my issues, even waiting on the phone, while I reset my system, because I messed it up...How cool is that. Great customer care...wish more companies did this , and , they spoke ENGLISH.!!!! April 7, 2013
Rated 4 out of 5 by great value I purchased this system one month ago..I was not expecting much for the price but the value was excellent. Easy to install. Had a problem installing software but Michel at customer service was quick to assist in getting it up and running. Great experience.  January 10, 2014
Rated 4 out of 5 by SURPRISINGLY AMAZED I came across this 4 camera system by accident , The price was right ! The equipment arrivedI opened it being in the security business i was expecting some flimsey eqipment , but amazingly it was very decent . I was sent with no instructions but its novice friendly! Pretty much 2 wires that can only connect one way. I clamped them to line them up,ran the wire to the tv and aligned it. I installed it. then i went to set up the software and hit a wall . I called their customer service and Michel was outstanding. We got everything working.But i had to hold for 2 hours on the phone on hold to get there but the care and end result was excellent. But if the engineering and production departments can find a way to reduce the size of the hole needed to get the connectors and wire, get better setup instructions,and possibly a better swivel on the cameras, it would have gotten a 5 Star rating, Also Michel at customer service went above and beyond, but the 2 hour wait was very discouraging, also the night resolution could be better. It has my stamp of approval !!!! January 8, 2014
Rated 5 out of 5 by excellent product and service The system works great. Instructions were the best written I have seen. Due to having the wrong type of IP address needed to call for help. Michel was very knowledgeable and helpful. Got me up and running to my iphone in no time. Thanks Defender for a great product. December 20, 2013
Rated 5 out of 5 by Great system! As one who is not very tech-savvy, the 1-step remote viewing was easy to set up. I had to call the help line to figure out how to see the cameras remotely; however, Michel was extremely helpful and within minutes I was seeing the cameras remotely. There is so much this system allows me to do. December 9, 2013
