Package of 4 Hikvision cameras comes with 4 cameras of 4 megapixel resolution and Wi-Fi. It includes a recorder with 4 outputs of 4 megapixel resolution, along with wires, power adapters, and installation items. Note: The cameras are Wi-Fi, but the difference is that it comes with a recorder that can install a hard disk of any capacity you need and for any time period you need, meaning you don’t need to install a memory card for limited storage like regular Wi-Fi cameras.
