Wireless camera with a 7-inch monitor using 2.4GHz wireless communication, capable of connecting up to 4 cameras and equipped with a recording function. - Brand: ELPA - Model: CMS-7001 - Type: Wireless Camera & Monitor - Screen Size: 7 inches - Wireless Communication: 2.4GHz - Recording Function: SD card compatible - Number of Cameras: Up to 4 connectable - Installation Distance: Up to 3 meters I intended to install this at home, but I ended up not using it, so it's a new, unused item. I did test the camera's operation, so it has been set up once. Please refrain from purchasing if you are concerned about storage by a non-professional. Thank you for viewing.
