This is my second unit. One of the channels went out after a year on the prior unit and I replaced it with this one. It works really well! The day recording is super clear and it's surprising how well the picture looks during the night. Set up is fairly simple and there's really no maintenance to it other than keeping the spiders off the cameras. Very happy with the unit. The signal to the cameras will penetrate brick and steel siding, but won't go through steel beams. That shouldn't be much of a surprise though. It works best with the antennae exposed and not inside a cabinet or desk.

One thing I need to warn you about is paying for the extended warranty through square trade. They wanted me to take the DVR unit and all the cameras to a shop and have it repaired. They said they would reimburse me for the repair. I wasn't about to pull down all the cameras but to appease Square Trade, I called around to every repair shop i could find and asked if they could repair the unit. They either told me they could not, or it was a replaceable item that isn't repairable. I went round and round with Square Trade and they finally told me to buy a new unit from Defender and they would re-reimburse me for the purchase after I send in the receipt. I haven't heard anything from Square Trade and will begin the process of bugging them until they either pay up or quit taking my calls. Their customer service and policy aren't worth the paper it's written on. Don't use them if you can keep from doing so. Defender gives you a full year warranty and after writing a review will extend the warranty another year. I didn't do that with the first unit I purchased. I'm not sure how it works? But they advertise it with a flyer shipped with the unit. Two years should be adequate. I spoke with Defender a few different times and they are great to work with.

If you made it this far, the camera system works great in our warehouse and office. Very happy with it!

This camera system gives great picture quality and does just what it says it will do

I have had this installed for two months in the Texas heat works like a champ!!! I love the wide periphial vision on this wireless camera!!!!

I just received this last night, I have some older wired cameras from Defender that still work great, but the quality on these wireless ones are amazing so clear and the colors are bright, I love the feature that you can zoom in if you pause the video. We had some people trying to get into cars lately and this is going to help tremendously to hopefully catch them. I am very excited to see how they work at night as my older cameras work good too. I am glad I found Defender I highly recommend you guys to everyone that is looking for cameras.

wish it came with the 69 page manual on how to update the system , and other features--but no complaints yet

I bought this on sept 1 and really like. I also have and wired setup with four cameras, which I bought 1 year ago and they are greeeaaatt.....

I bought this a few months ago and was not familiar with its set up, but customer service representative helped me in quick set up. Recently I noticed one of my cameras was not working and contacted defendant and Daniela, one of representatives from customer service helped me to fix this issue and she was very helpful, cordial and quick in resolving the issue.

Happy with my purchase. Easy to setup and use. Works perfectly for the needs I bought it for.

Set up two of these so far and work well. Manual is OK but I would suggest using videos from defenders website. Very well done and extremely informative. I was under impression that these systems could be monitored from your PC - NOT the case. I would suggest using a small monitor where you install the hard drive as it is easier to use than a cellphone.

So pleased with this cameras. Had packages going missing from my yard until I purchased these cameras. Great quality picture, easy set up!

I bought this system in july after one of the receivers of my 2 year old lorex system died and lorex could not replace it. I chose defender pro, given the broad distribution through walmart and amazon for easy refund/exchange and the company had generally positive reviews and the website is professional established.
Setup is relatively easy. Compared to my old lorex system, the box is smaller and comes with just 1 receiver (for all 4 cameras). Everything else is similar, even the cameras. The picture is much better since the defender pro is an hd vs my old 720p. There is no sound and no two way interaction. However, I do find the connection signal to be slightly weaker (i think it's a function of physics) and must have clear direct line of sight or max 1 barrier. On the other hand, there have been no interference with my 2.4G wifi. App interface is easy to use. I have not tried customer service so I don't have any comments. Overall, I'd recommend the product for regular residential use.

The shipment was very well packed. The setup and pairing the cameras was straight forward and easy. Picture quality both day and night is superb and shows details of each picture. Distant objects show up clearly. This is the third system I have worked with in the past 10 years and is by far the very best, the other companies just don't add up. Donna was very helpful in the selection of this system to meet my needs.

This system records and plays back videos very good. Very happy with this and the customer support team that answers the email questions I ask them.
