No. As most of our 4K security systems have more than 4 cameras, if they were to be wireless there would likely be interference and lag issues. To ensure an interference free experience and give you the option not to use W-Fi, our 4K Security Systems are a wired connection between the cameras and DVR.
8 megapixel, also referred to as 4K resolution, is double the clarity of a 4 megapixel (2K resolution) security camera! By investing in 4K resolution, the amount of pixels in your image is doubled, which gives you superior detail and allows for a higher quality, undistorted zoom.
Yes. You can share your Defender Empower App access with up to 20 additional users. Each user must download the Defender Empowerment App and create their own account before sharing access.
Recording time varies depending on the size of the hard drive, the number of cameras you have connected, and your recording schedule. Once your NVR is full, older footage will be overwritten to ensure you never stop recording.
