Section 1 - Product Overview
Introduction
The D-Link DCH-B112A1 Door/Window Sensor is a wireless sensor that connects to a DCS-8330LH Smart Full HD Wi-Fi Camera
with built-in smart home hub, as well as other mydlink Smart DIY devices with built-in hub functionality. You can install any-
where you want to detect the opening or closing of a door or window. If the sensor is triggered, it will send push
notications to your mobile device which helps you keep tabs on your home while you are away. You can also set it up an au-
tomation rule to trigger other devices such as the DCS-W118 Wi-Fi Smart Plug. Perfect for turning on/o a lamp or more when
entering/exiting a room.

Wireless Installation Considerations
The DCH-B112A1 Door/Window Sensor connects to your network using a wireless connection from virtually anywhere within the
operating range of your mydlink Smart DIY hub device. Keep in mind that the number, thickness and location of walls, ceilings, or
other objects that the wireless signals must pass through may limit the range. Typical ranges vary depending on the types
of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to fol-
low these basic guidelines:
1. Keep the number of walls and ceilings between the product and other network devices to a minimum - each
wall or ceiling can reduce your device's range from 1 to 30 meters (3 to 90 feet). Position your devices so that the
number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. A wall that is 0.5 meters (1.5 feet) thick, at a 45-degree
angle appears to be almost 1 meter (3 feet) thick. At a 2-degree angle it looks over 14 meters (42 feet) thick!
Position devices so that the signal will travel straight through a wall or ceiling (instead of at an angle) for better
reception.
3. Building materials make a dierence. A solid metal door or aluminum studs may have a negative eect on
range. Try to position access points, wireless routers, and computers so that the signal passes through drywall or
open doorways. Materials and objects such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors,
le cabinets, brick, and concrete will degrade your wireless signal.
4. Keep your product away at least 1 to 2 meters (3 to 6 feet) from electrical devices or appliances that generate RF
noise.
