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 dierence. 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.
