Installing The Camera • Before you install the camera, carefully plan where and how it will be positioned and where you will route the cable that connects the camera to the power adapter. • Before starting permanent installation, verify the camera’s performance by observing the image on a monitor when camera is positioned in the same location / position where it will be permanently installed. 4.1 Installation Warnings • Aim the cameras to best optimize the viewing area: select a location for the camera that provides a clear view of the area you want to monitor, that is free from dust, and that is not in line-of-sight to a strong light source or direct sunlight. • Avoid installing the camera where there are thick walls or obstructions between the camera and the receiver. • Avoid installing in a location which requires the wireless signal to pass through cement, concrete, and metal structures. This will reduce the range of transmission. For details, see “Appendix C: Facts About Digital Wireless Cameras” on page 10. • Select a location for the camera that has an ambient temperature between 14°F~122°F (-10°C~50°C) • Not intended for submersion in water. For outdoor use, installation in a sheltered location is recommended. 4.2 To Install the Camera 1 Screw the antenna to the back of the camera. 2 Use the included mounting screws to mount the stand to the mounting surface: • Mark the position of the screw holes on the wall. • Drill holes and insert the drywall plugs (included) as needed. • Firmly attach the stand to the wall using the provided screws. 4 Installing The Camera 3 Screw the camera onto the head of the stand (1). Adjust the angle of the camera until the desired view is set. Tighten the thumbscrew to secure the camera position (2). 1 2 4 Connect the power cable from the camera to the power adapter. Plug the power adapter into a power outlet or surge protector. 5 Installing the Wireless Receiver 5.

Appendix B: About Digital Wireless Technology The Digital Wireless signal transmission type used by the Lorex LW2275 Series is also known as FHSS—Frequency Hopping Spread Spectrum. This type of signal results in a private, interference-free signal. The 2.4GHz (2.400-2.480GHz) band is divided into sections or paths of 2MHz per section, and each second, the transmission signal hops hundreds of times in a specified sequence within this frequency range. The overall bandwidth required for frequency hopping is much wider than 2MHz; however, because transmission occurs only on a small section of this bandwidth at any given time, the signal being transmitted does not suffer from greatly reduced signal degradation and also avoids paths blocked by other devices that act as sources of competing signals. The strength of the signal being transmitted is set to be from 13.5-16dBm, which is much higher than the analog transmission signal allowed by authorities around the globe. When an image is captured by the camera, it is instantly converted from an analog to a digital signal and is packaged into small packets. With each successful transmission via the 2 MHz paths discussed above, the packets of information containing images are delivered to the receiver and decoded into analog information. The information can then be displayed on devices that are connected to the wireless receiver (RX). A device pairing process is required to synchronize the transmitter (TX, Camera) and the receiver (RX). This allows the transmitter and receiver to be on the same frequency and use the same algorithm for frequency hopping. This ensures that only the paired transmitter and receiver can maintain communication signal by hopping to the same frequency paths at the exact same time. As a result, the chance that other devices within the same frequency range are on the same frequency, at the same time and in the same order is vastly reduced. Note that the pairing process is already done at the factory for products that ship within the same packaging. 9 Appendix C: Facts About Digital Wireless Cameras 9. Appendix C: Facts About Digital Wireless Cameras 9.1 Wired vs. Wireless Cameras A wired camera has a video cable that transmits the video signal from the camera to a recording or viewing device. A wireless camera does not use a video cable. Instead, it wirelessly transmits the video signal to a wireless receiver that is connected to your recording or viewing device. Although the typical digital wireless camera is priced slightly higher than a wired camera, wireless cameras can provide cost savings compared to standard wired setups. For example, wireless cameras do not require cabling to be run between the camera and the viewing / recording device, which reduces installation time and cost. 9.2 Does a wireless camera require power? Yes. Wireless cameras require two power sources: one connected to the camera, and the other to the receiver. 9.3 How far can a wireless camera transmit a video signal? In an open field (with line of sight), a typical wireless camera has a range between 250 to 450 feet. In a closed environment—such as an interior of a house—the wireless camera range is between 100 to 150 feet. The signal range varies depending on the type of building materials and/or objects the wireless signal must pass through. Cubical walls, drywall, glass, and windows generally do not degrade wireless signal strength. Brick, concrete floors, and walls degrade signal strength1. Trees that are in the line of sight of the wireless camera and receiver may impact signal strength. The signal range also depends on whether there are competing signals using the same frequency as the camera. For example, signals from cordless phones or routers may affect signal strength. Range Limiting Reflection The signal reflects back Scattering The signal scatters back into multiple new signals Refraction The signal bends as it travels through an object (i.e glass window) 1Source: Xirrus (2010).

Retrieved online at http://xirrus.gcsmarket.com/pdfs/Xirrus_Wi-Fi_Range.pdf 10 Diffraction Attenuation The signal changes direction as it passes around an object The signal strength weakens as it passes through an object Appendix C: Facts About Digital Wireless Cameras Signal Reduction Through Materials Signal strength decreases as it passes through different types of material. Try to position your wireless camera and receiver in a location where the signal does not pass through metal or concrete blocks, which can significantly reduce signal strength (as shown in the table below). Material Signal Reduction (%) Plaster & Wood 10 - 30% Brick 30 - 50% Concrete Cinder Blocks 50 - 70% Metal & Metal Cladding 70 - 90% NOTE: Signals that must pass through wet or moist materials (i.e. shrubs and trees) may be significantly reduced. The stronger the signal strength, the higher the video frame rate. The lower the signal strength, the lower the video frame rate. Full signal strength (high frame rate) Low signal strength (low frame rate) 9.4 Are digital wireless camera signals secure? Yes. Lorex digital wireless products feature a wireless transmission method called FHSS— Frequency Hopping Spread Spectrum. This type of signal is highly resistant to eavesdropping as it generates a channel hopping sequence using an algorithm generated by the receiver, which only the camera can follow through the "pairing" function. FHSS makes digital wireless signals secure, private, and interference free. 9.5 How many frames per second should I expect from a digital wireless camera? Current Lorex digital wireless cameras offer 10 - 30 FPS (Frames Per Second) performance. Actual frame rate depends mainly on signal strength and resolution (see the chart above). Most digital wireless cameras support one or both of the following resolutions: QVGA and VGA. QVGA produces video at up to 25-30 FPS at 320x240 resolution. VGA produces video at up to 10-12 FPS at 640x480 resolution. 9.6 How many wireless cameras can I install? It is recommended to install a maximum of 4 (four) wireless cameras per system. 11 Appendix D: Troubleshooting 10. Appendix D: Troubleshooting If you have problems with your system, there is often a quick and simple solution. Please try the following: 12 Problem Solution There is no picture from the camera • Make sure that the camera is plugged into a power outlet and that the power adapter is plugged in properly. • Move the camera closer to the receiver. There is no audio from the camera or there are problems with the audio • Make sure that the white audio connector on the receiver is connected to the correct audio input on your TV/DVR/VCR. • Make sure that your DVR/VCR is connected to speakers. • Make sure that the volume is turned on. • Make sure that there is sound within range of the camera microphone. • If the unit emits a loud screeching noise (feedback), move the camera or receiver farther apart. The picture is dropping • Move the camera closer to the receiver. • Try repositioning the camera, receiver, or both to improve the reception. The picture is or has become choppy • The picture may become choppy when experiencing a lower frame rate (e.g. 6 frames per second vs. a higher 12 frames per second). • Try moving the camera closer to the receiver. • Remove obstructions between the receiver and camera. • Try switching to QVGA mode. Resolution will be reduced, but video frame rate will increase. The picture appears fuzzy • When viewing on a large-screen TV or monitor (especially high-definition televisions), the picture might seem fuzzy as the camera is limited to VGA resolution (640x480 pixels), while the TV or monitor supports a much higher resolution. • For best performance, use with TV/monitor PIP (Picture in Picture) function. Check your TV/monitor product manual to see if this feature is available on your TV/monitor. The picture is white • "Washout" or "white wash" can occur when a strong light source is pointed at the camera lens. The camera lens is not harmed during a white wash. • Do not point your camera towards a bright light source. The picture is pixelated • You may be in QVGA mode. Try switching to VGA mode by pressing the QVGA button on the receiver. Appendix E: Frequently Asked Questions 11. Appendix E: Frequently Asked Questions Q: What is the maximum distance I can have between the camera and the receiver? A: Typically 450 feet (137m) with a clear line of sight in open space, or approximately 150 feet (46m) in a house. Walls, studs, furniture will interfere with the range of wireless transmission. Q: Why does my "wireless camera" have a power cable? A: The term "wireless" refers to the lack of a video cable between the camera and the receiver. The camera still requires a power source. Q: What does 'line-of-sight' mean? A: 'Line-of-sight' means that there are no obstructions between the camera and receiver. Obstructions include walls, buildings, trees, and certain electronic devices. Materials containing moisture (for example, wet leaves) may also act as an obstruction. Q: What is pairing? A: Pairing is an electronic handshake between digital wireless devices. Pairing allows the devices to communicate exclusively with each other. Q: Can digital wireless cameras be paired to more than one receiver? A: No. Digital wireless cameras can only be paired to one receiver. This is to prevent interception by 3rd parties, and prevents any other device from picking up the signal—this also means that you cannot pair one camera to multiple receivers. Q: How can I extend the wireless range? A: For details, see “Appendix F: Extending Wireless Signal Range” on page 14. 13 Appendix F: Extending Wireless Signal Range 12. Appendix F: Extending Wireless Signal Range DISCLAIMER: Certain accessories are not available in all markets. There are several ways to boost your wireless signal as well as options to help you extend the range of the wireless signal. Clear Line-of-Sight The digital wireless signal is virtually interference free. However, you should always ensure there is a clear line-of-sight between the camera and the receiver. Clear line of sight Receiver Obstacles There should be little to no obstacles obstructing the line-of-sight between the camera and the receiver. Solid objects, such as concrete and metal, may limit the range of the wireless signal. Extending Your Wireless Signal Even with a clear line-of-sight between your camera(s) and your receiver, you may experience a lower video frame rate simply due to the distance between your wireless devices. Accessory antennas are available that can help extend the range of your wireless signal. 14 Appendix F: Extending Wireless Signal Range 2.4 GHZ Directional Wireless Panel Antenna Use the 2.4GHz Directional Wireless Panel Antenna (model #: ACCANTD9) to focus a wireless signal onto one specific camera in order to increase range of transmission (clear line-of-sight between the camera and the antenna is required). A 20 ft. extension cable is included help with proper position of the antenna. Directional Wireless Panel Antenna 2.4 GHZ Omni-Directional Wireless Antenna Use the 2.4GHz Omni-Directional Wireless Antenna (model #: ACCANTO9) to extend the range and boost the signal of several wireless cameras. You should position the Omni-Directional Wireless Antenna in an elevated position to provide a clear line-of-sight to the cameras. A 20 ft. extension cable is included help position the antenna.
