Setting up your viewing options for up to 8 cameras gives you the option to customize each area you wish to monitor.

Other viewing options include picture-in-picture, full screen, quad screen, 9 channel view, digital zoom and sequence switching.

    Much easier than older models to set up and use for networking

    JENKINS February 4, 2016

    I bought this dvr to replace one that was several years old and had gone bad. I was able to connect all of my existing cameras into the new dvr and was up and going very quickly. Very happy with the ease of the process.

    Happy guy February 2, 2016

    This is an impressive product for the price. Cameras have good resolution and the new ClearVu software was exactly what I was looking for.

    I encountered some difficulty in setting up my computer and my cell phone, however, after calling the technical support number and talking with Susan, the setup was successful with no problems. I would highly recommend your product and your technical support team

    This DVR is a great Product. Easy to connect. I really like the HDMI connection. It looks real sharp on my TV. The extended recording time versus my old one is a plus. I called Defender for help setting up the netviewer on my home computer and Mihel did a great job of helping me install a new program to get it done.

    I purchased this unit about 3 weeks ago and the function and picture/record quality is very good.  I have a macbook and I had to update my OS to use the playback software.  Best buy for the money a 1TB HD is included, can't beat this deal.

    Obsfest November 30, 2015

    Very happy with product features/functions.  I have two of the systems now and one of the hard drives failed on one my DVR's.  I contacted customer support and received  a replacement DVR under warranty.  Received the DVR quickly and was up and running again after just hooking up existing cables.  Very please with customer support and functions of this DVR system.  Would recommend this DVR PRO system with 8 cameras.

    MIke5 November 30, 2015

    I checked out other products this seems to be the best deal. I didn't give it 5 stars because this is a replacement DVR I had to buy. My first one stopped working after 1year 8months. Overall still pretty happy with it.

    tomcat20103 November 30, 2015

    I have now 3 of these dvrs.2 are 500gb and the other is 1tb.I am pleased with all 3 units.

    Herb November 30, 2015

    Well I bought the wireless system, however I wish I purchased the wired type of security system. I still had to run electric power to the camera's so I just would have been better off running camera cable. I have four camera's, backyard, 2 on the side and one in front of my home. They are clear and the night vision is good also. My problem is, all my camera's are within 45 ft. of my receiver's and two work as they should but one has a more than normal delay and the last one has a lot more delay and go off quite often from not getting the signal to the receiver. The two that have the delay are just across the garage, at each corner, from the receiver's. If I had purchased the wired system I don't think I would be having this problem. Example of the delay. My wife entering in our home from outside the garage and she is all the way in our home and she still showing on the camera outside.
    I'm not happy but I'm stuck with it. I had a wired system in a business and it was perfect. This one? Like I said, not happy. The neighbor is wanting to see it, but I'm embarrassed to show it with the camera delays.

    Naenae November 30, 2015

    I was given these cameras as a Christmas gift. Good viewing. Range not so good. Had to run wire to connect to a source of eleu, closer to the camera. Further away the wiring from the camera, no signal at all. Also, one camera just refused to work at all. No signal from the camera at all. Overall, I like the cameras and would recommend.

    DaveP November 30, 2015

    Excellent wireless camera. Very clear and easy to install and set up

    Dooman November 30, 2015

    I currently own a garage door business and we install camera systems through another company that cost 10 times what the defender unit cost and we receive the same results with the defender for a fraction of the cost. This unit is awesome and Sarah in cust. service is great.

    I purchased this system going on three months ago. I am not usually pleased with products I purchase for one reason or another. This Purchase is by far the best investment besides my retirement fund I made this year. Yes there are some shortcomings however the piece of mind vs. the shortcomings were well worth it. These were the issues I had

    1. I had to hire someone to install it so that cost more money. If you have the correct tools and skills you will save yourself some money.  Just keep in mind YOU are the one in the attic. remember dress for the job and have safety glasses and a Dust mask your going to need it. Or just pay someone!

    2. when it came to setting it up I was lost but the contractor who installed it programmed it and even programmed it to my cell phone.

    3. I haven't mastered all the features yet. I really like that I will be able to set the cameras to motion if I want and have pictures sent to my email while at work if they are set off. 

    4. Camera location and fields of view, make sure you overlap the camera angles if possible. I have a overhead car port which restricted me to where I could locate the cameras.

    5. I only went with six cameras when I should have went with 8 initially. I will have to add two more soon.

    Bottom Line Up Front!! How much is your valuables and Safety of your family worth to you!! and not necessarily in that order.

    go to the web site like the phone service prompts you to, and they really do get back to you quickly. I waited on the phone until I was just to frustrated and hung up, went to the defender site, left my info and a time to call, and Michel was calling me at the time I chose. within 20 mins I was up and running again. thanks again Michel.
