12D-Link DCS-820L User Manual
Section 2: Installation
This D-Link camera can connect to your wireless network 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 camera and other network devices - each wall or ceiling can reduce your camera’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 camera 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 is not in use.
