Wireless Installation Considerations
The D-Link Wireless Network Camera lets you access your network using a wireless connection from anywhere within the
operating range of your wireless network. However, 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 follow these basic
guidelines:
1. Minimize the number of walls and ceilings between your adapter and other network devices (such as your
Network Camera) - each wall or ceiling can reduce your adapter’s range from 3-90 feet (1-30 meters).
2. Be aware of the direct line between network devices. A wall that is 1.5 feet thick (.5 meters), at a 45-degree angle
appears to be almost 3 feet (1 meter) thick. At a 2-degree angle, it looks over 42 feet (14 meters) thick. Position
your 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 dierence. A solid metal door or aluminum studs may weaken the wireless signal. Try
to position your access points, wireless routers, and other networking devices where 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 at least 3-6 feet or 1-2 meters away from electrical devices or appliances that generate RF
noise.
5. If you are using 2.4GHz cordless phones or other radio frequency sources (such as microwave ovens), your
wireless connection may degrade dramatically or drop completely. Make sure your 2.4GHz phone base is as far
away from your wireless devices as possible. The base transmits a signal even if the phone in not in use.
