I purchased a Crenova® Waterproof 1280*720P HD ONVIF iCloud Webcam Mini Dome Security IP Cam IR Night Vision Camera Outdoor Indoor, from Amazon.com. The camera is simply mounted on the inside of my porch facing the door/mailbos and partially covers the driveway. After the installation I noted that my wife's small flag and wind chimes kept setting off the camera. I placed two "masks" over the offending things. Later we moved the flag. I have attempted to remove the masks without any success. I removed the camera, re-installed it...yet the "Mask" remains. Finally I sent Crenova an e-mail.... and they simply reimbursed me for the camera, my lucky day. I don't plan on taking the camera down... it works fine except for the "mask".... Just wondering if anyone else has ever experienced this. The camera is an IP Camera and I save the images/video's to my home PC.
