ARE THESE 4K SECURITY SYSTEMS WIRELESS?
ARE THESE 4K SECURITY SYSTEMS WIRELESS?
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.
WHAT IS THE DIFFERENCE BETWEEN 4K (8 MEGAPIXEL) AND 2K (4 MEGAPIXEL)?
WHAT IS THE DIFFERENCE BETWEEN 4K (8 MEGAPIXEL) AND 2K (4 MEGAPIXEL)?
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.
