I figured if I didn't like it, what the heck,it was only $19!! I was pleasantly surprised at the quality of the camera and the video quality. The color is a bit over saturated, but looks good. The night vision is pretty good also. I can see my whole front yard at night and it is 30 by 25 feet. Not bad for under $20 with Prime shipping. I found that good quality coax made a significant improvement in picture quality and clarity. When I installed the camera I used some really cheap coax/power/audio cable that I bought on desertcart with the camera. It was a very thin 100ft cable, about as thin as 12 gauge wire. Not good for video! Picture quality was about what one would expect for a $19 camera, crappy! On a hunch that the coax was to blame, I tried some 75ohm RG6 quad shield coax that the Comcast cable installer left me about a year ago. He told me it was the best for video applications, that's why they use it. It cost me $22 for a 10 pak of the BNC connectors needed for the cable and camera. Already more than the price for the camera, and if I had to buy the cable it would have been probably twice the price paid for the camera. BUT!, the picture quality was much better! I used the original cheapo cable for the power feed only and didn't bother with the audio, but it is there if I need it in the future. So, I spent $19 for the camera and about $30 for the coax/connectors(if I would have had to buy the coax) There are video/power combo coax on desertcart and elsewhere, but be sure to buy the best you can find. If you want the best video quality your camera is capable of you must use quality coax! You could use an amplifier close to the camera, but crappy coax will still degrade the signal. If your coax run is more than about 120 feet, you will still need quality coax and an amplifier! Of course there is the wireless way to go. The same conditions apply to wireless transmitter/receivers, you must use quality components in the system to get a quality video picture. I have a $100 camera I put up about a year ago(with good coax), and now a $19 camera(with good coax) and the difference between the two is very hard to see. I'm happy with this bargain camera and plan on buying 2 more.....
