 RF-Link's
8-channel A/V module is the foremost design in the 5.8GHz RF transmission. It
is mainly used in the outdoor surveillance camera application, where the feature
of 8 RF channels available for manual selection is quite popular.
In
addition, the issue of interference commonly seen in 2.4 GHz home entertainment
market is also getting more and more wide-spreading in the surveillance industry.
When incorporate with high-gain antenna, the RF transmission could be
sent over 10,000 feet, this make AMW-5880 the best solution provided in OEM/ODM
specialty market.

Features
|
- Strong
immunity to interference generated by all devices
operating at 2.4 GHz, such as Cordless phone,
Microwave oven, 802.11b and g, and even 802.11a
using 5 GHz.
- Providing
8 RF channels for manual selection, it can be
increased to 16 RF channels upon request.

of penetrating thru. 3 concrete walls (MINIMUM
transmitting distance of 300 feet with clear line
of sight).
- FCC
& CE certified.
- EN
300 440 certified.
- Adjacent
channel interference is minimized.
- All
8 RF channels can be used simultaneously.
