Other viewing options include picture-in-picture, full screen, quad screen, 9 channel view, digital zoom and sequence switching. Each recorded area is complete with time and date stamp so you can search by event and find recorded footage from each area you are monitoring.

Great very easy to use and setup

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.

DaveP November 30, 2015

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

EDWARD November 30, 2015

I bought this unit hoping that I would get better night vision. The unit did slightly better then the 75ft night vision camera. but did not go the full 100ft.

Syfynut78 November 30, 2015

This system, though you can only get it in 1TB or larger now, is overall good. It is not quite as easy to set up as stated, this is because the instructions are hard to read and the CD/DVD is worthless. Once you get past the set-up stage the cameras 75ft night vision is pretty good, and daytime clarity is very good also.

advwarz54 November 30, 2015

i have 8 of these babies and now my wife and i feel so much safer

mikbig1 November 30, 2015

Bought two cameras and installed a couple months ago. Decided to order two more. No problem, had them up and running in five minutes. I would definitely recommend this setup. Didn't need support this time but did the first time and support is great.

bluewrench November 30, 2015

Ive purchased several different brands of cameras and these are by far the best execpt the wireless range advertised is not right. I have reciver next to window and it bairly reaches 180 feet. Ive messured. Nothing in way of signal exept a wood wall. My lorex and security man cameras have that beat but the quality of the defender camera, picture, and wide view is by far better than any other even my other brands of wired cameras. Night vision is by far the best but would be nice if it were more spread out rathere than a spot light efect. Night vision is beter than advertised i think it reaches very far but not spread out. Id give it 5 stars if the wireless range was beter. Would be awesome if had a mic and would sound as good as the security man cameras then would be a perfect camera. :-)

Carolyn November 30, 2015

I added cameras to my system with on problem,very easy to configure.

jessbff November 30, 2015

We bought these to add to the DVR camera set that we bought

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.

jvar2992 November 30, 2015

this system is good but not great the picture has no hd witch all wireless systems now have....also my main camera has to be reset every now and then or else the video will freeze ,not good

Kenneth November 30, 2015

Advertising & specifications indicates a wireless range of 1000ft or 750ft or 400ft or 150ft. Seems more like 100ft wireless range. Installed 2 cameras one works off and on the other not at all. The cameras are located within 5 foot of each other looking different directions. The wired system works great, seems like Defender needs to get its act together on wireless. I have already had to tell a friend not to buy the Defender Wireless system.

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.

Mister G November 30, 2015

I purchased these cameras to expand my sentinel unit. The 800 cameras are much better than the 600 cameras I had with my old unit. Picture quality is very good.
