Your 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 by 1-30 meters  (3-90 feet).

2. Be aware of the direct line between network devices. A wall that is half a meter thick (1.5 feet), at a 45-degree 

angle appears to be almost 1 meter (3 feet) thick. At a 2-degree angle, it can appear over 14 meters (42 feet) 

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 difference. 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 (fish 

tanks), mirrors, file cabinets, brick, and concrete will degrade your wireless signal.

4. Keep your product at least or 1-2 meters (3-6 feet ) away from electrical devices or appliances that generate RF 

noise.

5. If you are using 2.4 GHz cordless phones or other radio frequency sources (such as microwave ovens), your 

wireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz 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.
