In a perfect world, answering the door would be completely safe, even at night. However, in this day and age, people have to be careful that a potential guest isn’t an attacker.
Cannon Security Products has introduced a neat way to see who is at the door, without placing a homeowner in jeopardy. The Digital Door Viewer can be installed on most doors and programmed to take photos or video of all visitors, even in low-light areas. It can be set to turn on when the doorbell rings, or with its motion detector, and it stores those images on a Micro SD card by date and time.
At almost $300, the camera is not cheap, but the added security could be well worth the price. You can view who is at the door on its LCD display from a safe location. Also, you can learn who is walking up to your door, whether it’s a delivery person, prankster or scoping the house with bad intentions.
