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.
