Use the Masking feature to block out a portion of the scene from an individual camera such as a cash register or safe while still seeing the activity around the masked area.

Each recorded area is complete with time and date stamp so you can search by event and easily find recorded footage from all channels.

    Your technician Michel went through this whole system and show me how to make everything work he was professional like you wouldn't believe I really want to thank him so much if there was one way I can still use hand I would but you guys have a fantastic check-in Michel

    rrawtry January 26, 2016

    Overall, the product is good quality and easy to setup. The problem comes in communicating with a computer and the lack of a comprehensive owners manual included. Stand alone with a monitor only and it's an awesome setup!

    George November 30, 2015

    Have tried for the last 1.5 months to get the iphone app to work and gave up. The camera resolution as far as viewing live is fair, but the quality of the recorded feeds are pathetic. The idea of a security system is to be able to refer to the recorded feeds for reference and on the highest settings for the best resolution this unit is a failure. Even an email to Defender themselves told me that is as good as it gets. Don't waste your money on this unit you will be disappointed.

    Jeannette November 30, 2015

    We bought the Defender 21152 for our mobile home community and are so happy we did. The installation process was so easy and the mobile installation was a breeze thanks to Daniela who walked me through it. Daniela was very patient and personable. I would recommend this product to anyone.

    frenchy November 30, 2015

    bought my defender pro system 16 channel a month ago and am very pleased with the overall quality and value! installation was simple and straight forward. I had a little technical glitches when trying to remote view but Michel at tech support walked me through my problem and solution with professionalism and enthusiasm! thanks Michel!

    Lobo2010 November 30, 2015

    This is my second unit that I purchased. They are made of high quality material that is almost vandal proof.

    Easy to install, configure and use.

    The clarity of the cameras is almost as good as the pictures on out television!! This includes the night vision.

    I had an opportunity to work with the support department, they are very knowledgeable, cooperative and concerned about the customers satisfaction.

    After looking at many products, I find that the Defender systems provide many extra features that others don't and, for the price, you are purchasing a high quality system!!

    Double T November 30, 2015

    I'm not scared or nor paranoid, but I believe every home & business should have a surveillance system. Already had to use the rewind & view feature to see what happened in a certain situation when I wasn't present to know the circumstances. I like the system other than the android app needs some improvement. I have to turn the DVR off then back on every day or two because it will not load on my phone app. I'm an amateur tech person but was able to get all cameras, DVR up & running. Overall great value for the money cause I did a lot of research before going with this system & brand.

    ChefTom November 30, 2015

    MICHEL WAS AMAZING!! We are very happy about the service, cameras, the ability to check on our home when we are away. We could have never gotten set up without his assistance. THANK YOU!!

    Lucky November 30, 2015

    Michel was excellent at helping me access my network for mobile viewing.

    Rev Jackie Jones November 30, 2015

    Customer service was great. the defender works good. even with windows 10.
    I have not been able to view for the internet yet. Still working on that.

    Junior Mc November 30, 2015

    My son and I just installed this new system and I sure like what I see so far. Very Happy

    RayRay November 30, 2015

    Bought this in May 2015 and has worked flawlessly. Easy installation took me just 4 hours to install and connect. As for remote viewing, took less than 5 minutes on an android device. Glad I chose this system!

    stephen November 30, 2015

    Great camera set, easy to set up and use, awesome customer service, the networking specialist, Michel, was extremely helpful!

    Intern November 30, 2015

    I purchased this system to monitor complex integrated manufacturing equipment so I could record and review the footage in case of a machine malfunction or p.l.c. error. The cameras work great in low light with color without switching to night vision which was a problem with a different Defender system I had purchase in the past. The cameras and DVR work great. I was disappointed with the PC software package that came with the system so I could patch the DVR into my network and view it remotely at another PC. I ended up dumping the software and hard wiring the second pc directly to the DVR running 125 ft of CAT-5 and VGA cable with a KVM switch.

    The computer mouse that came with the system and one of the eight cameras were defective. Defender quickly responded to my warranty issue and quickly replaced the defective items. I did not need all the cameras in this set but it was cheaper to buy this set than a smaller set.

    Overall, for the price, this is a good system, easily installed, and easy to use.

    Deer watcher November 30, 2015

    I have had this system for a few weeks and have found it very easy to use. The images are great and the equipment is of very good quality. I soft wired the cameras to study the viewing angles and am now hard wiring each camera in place. I can view all cameras from my IPad and IPhone. I highly recommend this system for any DIY installation
