I have had no problems with mine. I was extremely pleased with the ease of the setup. I bought mine at BJs when they were on sale. The system also comes with a SD Card that will hold up to 55 hours of recording. The system does not record constantly. Only when something activates the sensors. It has several settings so you can adjust it to you liking. The best part about the wifi is if you want to move a camera just unplug it and move it to another position. The only downside is the camera has to be within 10 or 15 foot from an electrical outlet.
