System Overview

MicroPower Technologies has developed a unique proprietary power and wireless

technology called “TrustLinx™”, which enables the long-range wireless transmission of

digital video while using only 10% of the electrical energy that most common wireless IP

cameras consume. With this patented technology, the MicroPower wireless Video

cameras can remain fully operational for up to five days in complete darkness, utilizing

only the internal rechargeable batteries. This enables the camera to reliably operate 24

hours a day through most weather conditions, without any performance loss or need for

maintenance. Additionally, the TrustLinx radio technology does not conflict with other

wireless technologies such as traditional Wi-Fi (802.11b/a/c/n), while still retaining the

ability to reliably transmit high-quality digital video up to distances of 1/2 mile.

The patented TrustLinx technology eliminates the need for trenching and/or long cable

runs to remote outdoor cameras, significantly reducing installation time, labor costs,

and allowing cost effective remote video coverage in locations where surveillance was

never before possible.

In the 2.4 GHz ISM band, referring to the OSI 7 layer networking model, we use Layer 1

for the physical layer and Layer 2 for the data link layer. We do not use Layer 3

(network layer), Layer 4 (transport layer) or Layers 5-7. Therefore, we utilize the

physical radio and the data link that organizes the bits into packets. These packets are

not Wi-Fi, TCP/IP or any other topology. The hub receives the packets from the camera

and although the packets comply with the 802.11 Layer 2 data link format, the content

is proprietary. Because we are receiving camera data it is a one way stream from the

camera to the hub. We do not enable the transmit from the hub to the camera using

this radio, therefore the normal mode of operation and the only mode that can be

activated by the user is receive mode.

The MicroPower designed card is designated the Hub Controller Board, or HCB. It is also

a mini PCIe card. The HCB is controlled by an on-board microcontroller. The

microcontroller has direct access to a 915MHz radio transceiver. The operating

frequency of the radio is derived from a 48MHz crystal, and FSK modulation is

employed. The radio is coupled with a power amplifier and LNA to boost output power

to approximately 13dBm. Matching and filtering networks are employed to minimize

spurious noise and harmonics. One of multiple channels in the 909-921MHz ISM band

can be selected for operation. This allows the system to select a channel to avoid

interference with other devices operating in the band. The channel selection is

determined by software on the host computer and communicated with the HCBs

microcontroller using an internal USB interface.

Up to six (6) wireless cameras can be associated to a single video hub. The video hub is

the only data connection point to which the Video Management System (VMS) will

communicate and obtain the remote video streams. The standard TCP/IP data from the
