I am not new to Defender security cameras and have been pleased in the past. It was time for soemthihg better so I thought these would be a good choice. I am no pleased with the "wireless" as they still need a power source. I did know this drawback going in so that's on me. Still would have prefered some alternative to a plug in system. Its ok for inside but not for outdoor use so much.
My biggest complaint and something I didnt know when I bought this system was that there is no option to block areas for motion sensing. In other models (including my old one) I was able to program the system to avoid detection motion in certain areas of the camera. This comes in handy when you live on a busy street or want to avoid that tree blowing in the upper right hand corner of the screen.
For this reason the cameras area almost worthless because there is absoluetly no way I can watch my front door and not detect the motion of the cars on the street.
This is beyond disappointing. I would return it, however I didnt set it up until after I had it for 30 days. I would look for another model if I could do it again.

Took me a while to figure out best place to put cameras so they would sync well. Once I figured it out works great. I had the Phoenix model for 6 years and loved. And I decided to upgrade. So much clearer and love the app. Phoenix still working so put inside in garage and workshop. I really love the new ones. Love love love

I purchased this wireless system a year ago and when I needed another 4-camera system this year I bought the same one despite warning from tech support that they might interfere each other. I took my chance because I did not find another similar system that beats the Defender’s. This system has an excellent receiver, impressive night vision cameras and great tech support. I am glad I purchased the second system because both works fine with no interference.
One negative aspect is the process of backing up videos to a flash drive which is a bit cumbersome because it uses the same USB port that is occupied by the mouse. It would be perfect if there is an extra USB port so there is no need to unplug the mouse for the flash drive.

Just finished the install and wow it worked out great. Had a similar wireless system with another company but they no longer offered this model and I didn't want to change to the battery wireless as its undependable. After lots of research of other companies I decided to pick Defender as the ratings were rather high and proved to be a good choice as its an awesome product. In addition, It was an easy install but would recommend that you don't rush the install put lots of thought to outlet locations as the wires are about 8 foot in length. After install take a couple of days before you fine tune stuff otherwise it will drive you nuts. What I also like about the structure of the cameras is its all plastic the old one I had was connected to a metal base and it rusted this is well constructed and obviously wont rust. That said, I would highly recommend this product I am a very meticulous person and spend lots of time on research before I purchase anything, buy it. Techie B

My experience with Defender so has been good. Wireless camera gives me freedom of mounting a camera anywhere as long as there is power plug available.
Power adapter for one of my camera died but Darrielle from defender support was very quick in sending me a replacement. Thanks Darrielle for quick turnaround.

I recently had a camera go out just before going on a trip Darrielle in customer support has been so helpful in quickly getting me a replacement, before my trip. Keeping me informed at each stage of getting the camera to me. It arrived in time for me to install it and have everything working before my trip.

I have also used their customer service for questions during the original setup. Couldn't have been easier and helpful.

Congratulations on a great customer service.

Customer service is excellent. They answer the phone and try to help the best they can I spent several minutes on the phone today with Mike trying to fix my system. He walked me through step by step procedures to try and fix the problem. My cameras are to sensitive and give numerous false motion emails Shadows continue to set them off and the sensitivity needs turned down to solve this problem. I get 75 false emails each night I hope Mike contacts me with a solution to the motion problem

I wanted to like this system, the cameras had good quality, but after a month of working great i have had nothing but problems with this system. Customer service works with you but problems keep reoccurring. 1st the camera keeps losing its signal , especially in cold or bad weather, then had problems with DVR. Both camera and DVR were replaced. (however anytime they send you a replacement YOU have to pay for shipping to send the old equipment back) Now my 2nd original camera is doing the same thing. I have moved the system to be close to the cameras doesn't make a difference. I cant be climbing up a ladder to re-pair the cameras every time they go out. What is the point of having a camera system if it doesn't pick up what going on at all hours. ALL OF THESE PROBLEMS HAVE OCCURRED IN LESS THAN 3 MONTHS. BUYER BEWARE!!!

Reached out to customer support again requesting refund for defective product and Defender told me since it was purchased through a 3rd party, i only had 30 days to return. WAY TO STICK BY YOUR PRODUCT. Luckily the big box store i purchased this item from is refunding me my money for this faulty product.

I am happy with my purchase. I do wish you didn't need to hook up to a monitor with set-up and that alerts were already set up to send to my phone and only needed to be adjusted instead of set up from scratch. The wireless capability is good and the video is very clear!

I was having a problem viewing cameras on my tablet. I contacted Defender via their website and posted my issues. Within minutes Darrielle contacted me via email with a solution. Everything is working now. Thanks Darrielle.

I purchased the the Defender series wireless cameras 2 months ago. I am pleased with being able to monitor the cameras on a PC and on a cell phone or tablet. The video quality is great with a very clear video during the day. The video at night still shows detailed images in low light conditions.

Bought it several months ago and didn't set it up other than just through the window of the house looking out and in the same room as the DVR. They all worked fine.

This weekend I mounted two cameras outside approximately 25 feet from where the DVR is located (and its a regular house with basic walls and doors and no items that may interrupt a wireless signal). One of the camera's live video signal immediately turned blue and the other wouldn't get signal back to the DVR. The one with the signal loss was literally outside the house and 3 feet away from the one inside the window that worked. I couldn't get either of the two outside ones to work properly. The two in the room with the DVR still worked properly.

Did a firmware upgrade to the DVR as per the websites instructions hoping that would resolve any problems and now nothing works, I can log into DVR and access all the adjustable functions but can't see, or pair cameras. The info window says cameras are offline??? Tried everything in support troubleshooting to pair cameras, even one that I placed 3 feet way from DVR and nothing works. Also can't find anything under support for "cameras offline". Will chat with support when they are open and see if they can help me.

I will update this review with an updated detailed, fair and honest review depending on the the support received to see if they can resolve the issues. I hope that they help me and can report back with positive results and a positive review and confirm or not if the company and support stands behind their product

I will also update the review and comment on the extended one year warranty which Defender says they give if you leave a review. I trust this will not be an issue.

Since the first day I installed the cameras the DVR would not record motion or sound a alarm. I have been in touch with the support department several times over the last few weeks. They had me try many things to resolve my problem, none of them worked! They told me it was a problem with the Defender HD app and they were working on it.

That was almost a month ago and I have not heard back from them since! It's like they just forgot about me I said they should send me a new DVR and they won't do that either.

I have almost given up on getting the Defender system to work properly.

TAKE MY ADVICE, DON'T BUY DEFENDER!

Information leads one to believe a monitor is not needed, however it is absolutely needed to operate the system effectively. I bought a 19in TV at walmart for $88 that works well. The quick set up info supplied in the box falls far short of whats needed to get every thing working. The support is put of Canada and that alone makes the difficulty of support tolerable. However the seems to be a lack of good information flow or training, as it took 5 days and three different support people before I got the problems with the DVR setup solved. Finally Daniel who was the last contact had all the knowledge necessary to solve the balance of the setup issues. The first 4 days where wasted trying to work with a DVR that needed its firmware updated, which involved them sending a email link for me to download onto a thumb drive to be plugged into the DVR to update it. No direct update! AT this point I'm not sure all problems with the DVR are resolved, but the set up is complete.
