Cannon Security Products has introduced a new way to discreetly identity who is at the door—the Digital Door Viewer.

The Cannon Digital Door Viewer can be installed on doors between 1.37-inches and 4.13-inches thick, and can be programmed to take photos or video, with a panoramic view of up to 165 degrees. . It contains a .3 megapixel camera with photo and video capability, and includes a motion detector for activating the camera. Photos and videos are automatically placed in folder labeled with the date and time of their capture and are stored on a Micro SD card (up to 32 GB).

The Digital Door Viewer also acts as a doorbell with seven different ring volumes and multiple ringtones. Settings can also be adjusted so that the LCD turns on immediately as the doorbell is pressed, or even whether a photo or video is captured upon the doorbell being rung.

The LCD display is 2.25-inches wide by 1.625-inches high and can be programmed with the current date and time. Users can choose between five brightness settings and adjust how long the screen stays lit when activated. It also has an infrared LED feature that provides a night vision effect for areas with low light.

The Digital Door Viewer comes in a silver finish and operates on a rechargeable 1500mAh lithium battery. It can be recharged using a supplied charger and an LED low-battery indicator lets users know when it's time to recharge. The Digital Door Viewer comes with a 90-day warranty and a suggested retail price of $279.99.
