Answer the door from anywhere in your home - without having to actually open the door! The Samsung Video Door Phone lets you see who's ringing your doorbell, without you ever being seen. If you choose, you can also converse with the person at the door. It's the perfect way to distinguish expected visitors from pesky door-to-door solicitors. See Who's There Before You Answer - when your visitor presses the call button on the outdoor camera, a chime will ring and a black & white video image of the visitor will be displayed on the phone's 4" flat CRT screen. If you want to talk to your visitor, simply pick up the handset and begin speaking. The camera's built-in microphone will pick up your visitor's voice automatically. Even if your visitor knocks on the door instead of pressing the doorbell on the camera, you can still activate the system simply by pressing the "monitor" button on the video phone. You can also use this feature to investigate suspicious noises. The monitor will display what the camera sees for 20 seconds, so you can get a clear view of what's going on outside without compromising your safety. The camera, rated for .5 lux, uses infrared illuminators to see what's happening, even at night.
The Samsung SDV-410Y-R Video Door Phone Security System is a basic, easy-to-use video intercom system that is ideally suited to security-conscious business or home owners who want to know who is at the door. This system includes one four-inch flat CRT screen monitor with a built-in telephone-style speaker and microphone for two-way audio to a camera location, but will support up to three monitors per camera. With a smart design and single push-button operation, the SDV-410Y-R allows a remote door lock-release function. The camera with this system is simple to install and utilizes a 0.33-inch B/W (black-and-white) CCD (charge-coupled device) image sensor with a 3.7mm fixed lens and IR (infrared) LEDs (light emitting diodes). This unit provides a horizontal resolution of 420 TVL (TV lines), down to a minimum illumination of 0.5 Lux to infinity, and even 0 Lux within a limited range. The SDV-410Y-R's camera runs on 12-volts of DC power via its connecting cable through the monitor, and has an operating temperature of -20 to 50 degrees Celsius. Users should note that the CCD sensor may become permanently damaged if exposed to long hours of direct sunlight or halogen light, so the camera should not be mounted or pointed directly at the sun or other bright-light sources.
