Question: Can you measure the length of the wire on the ac adapter and tell me how long it is?  Thanks.  It's not in the details/features.
Document: Easy fix, and within a 20 minute call to Defender had the promise of a new cord to be shipped to me.Video quality is.... average at best, enough to make out most details, but not spectacular. Night vision is quite clear and from a good distance. Sound quality is actually very good when using the 2 way communication. Monitor is a nice addition, but a very washed out screen.Features of the receiver are basic, but adequate.
Picture (color) and sound is good especially for the money. Not HD of course, but good enough to identify someone. The camera has an aluminum body and is very sturdy and well built. With the power cord for the camera, and the adapter cord, you have enough power cord to reach an outlet from the camera almost anywhere. I am guessing the combined length is about 14 feet. The camera found the receiver instantly and automatically.
After reading both positive and negative reviews, I decided to give this a product a try as it is easy to setup and doesn't need any IT knowledge like the IP camera does. I did a test by setting a first camera in the living and dining room which is 28 ft long from edge to edge and another camera at the basement which is about 35 ft away with a floor in-between. The first camera captured an outline of every object at day time, however, the details are all missing.
I think this could be resolved if the antennas on both camera and receiver were a little better, or perhaps provide a flexible length of coaxial cable so the antennas can be oriented in a different location.
If you want to be up and running in no time then this set is for you. I had it working in twenty minutes. Perfect for monitoring my driveway. Great picture, intercom and ease of use. Lots of cord length. I have no complaints.
Works fairly well, not perfect, but does the trick. The night vision is good enough to see things, but not so clear as to make out critical details. I have 2 cameras running and it works just fine for what I needed it to do.
Small area such as a bedroom about 150 to 200 sq ft2_You plan on having both receiver (the monitor) and the camera setup on the same floor3_You just want to capture the activity but not the details in a larger area4_You want a plug-n-play system
1. resolution not good.2. does not cover critical areas in detail3. does scan day to day traffic i n the area.4. my property was damaged and your system did not show the critical details for me to  pursuit legal action.
This is used and I didn't purchase this used. It has been out doorsAre you going to tell me what to say?
For the price this system has great features. I was surprised how well the night vision actually worked and the LCD control panel is very convenient.
Answer: Only 3 ft
