About 2.4GHz Digital Wireless Signal

This innovative digital wireless solution integrates advanced Frequency Hopping Spread Spectrum (FHSS) technology. This technology greatly reduces the interference that comes from other devices using the same radio frequency (2.4GHz), e.g. WIFI, Bluetooth, cordless phone...etc. You can now experience improved wireless surveillance quality without flicker and noisy images. However, weaker signals (lag or still image) may be observed from time to time, depending on the environment where the system is installed. Complies with FCC part 15.247, ETSI (EN) 300 328; audio/video signals transmitted out up to about 500 foot (150 meters) line of sight can be supported. Line of sight installation though, is usually not a common practice. Factors affecting the transmission include microwave ovens or other high frequency electromagnetic waves. Reinforced concrete walls, large scale metal products, and metal furniture should not be located near the camera or the monitor unit. Do not place near water. Person walking by may cause unstable signal quality.

How to improve the wireless signal quality

If possible, remove obstacles in between the camera or the monitor that might reflect the signal. These could include furniture, cabinets, etc. If you feel the wireless signal is not good enough, place the monitor at a new angle, readjust its position to make an improvement, or simply move the camera closer to the monitor.

Why Image Compression?

In order to provide a private and interference free wireless service, this digital wireless solution works on a 2MB narrow hopping band. Different from traditional 2.4GHz analog signal, this digital wireless signal is compressed and presented as Motion JPEG (MJPEG) format. By digitizing and compressing the raw analog data, the bandwidth is used more efficiently and securely. Consequently, you might observe an indent image line if the signal is viewed on a larger display monitor or plasma TV.
