USER'S GUIDE

1.1 Gentral:

Video modem «OKO», «OKO-M» is a compact device designed to digitize color of B/W photos

and video information obtained from 1-4 CCTV cameras and real time transmission using the following

channels:

Municipal public phone network over any distances;

With 3-wire cable up to 100 m;

With 4-wire twisted-pair cable up to 1200 m (Baud Rate 115 K) up to 10 km with slower rate

(Baud Rate down to 9600) using set of adaptors RS232 – RS485;

With GSM, GPS or radio channel and an external modem supporting СОМ port (RS232) and

the required communication channel;

With leased (physical) 2-wire line using a pair of external modems operating over the physical

lines.

Reception is effected on PC through COM port or, when using public phone network, through a

common fax-modem. Information is displayed on the PC display by means of supplied software;

simultaneously one can view 8 selected fragments, record wholly or partially a photo and video

information on PC hard disk.

Video modem «OKO-M» has a built-in 56 K fax-modem 56 К, whereas video modem «OKO» has

only a COM port for direct connection to PC or through an external modem.

In off-line video modem does not require persistent operator's connection. When either the built-in

motion detector or the external sensor comes into action, the video modem takes a snapshot and/or

records video clip to the buffer, followed by autodial to the user's preset phone number.

The program supports simultaneous application up to 16 video modems, i.e. establishing several

connections (if required number of COM ports or modems connected with PC and coming to PC

phone or other lines are available).

1.2 Basic operating modes



―lens‖ – virtual channel with magnified area of the original image



―strobe‖ – ―decimation‖ of video stream over time (temporal decimation)



―camera‖ – high resolution and/or absence of image compression



―waiting‖ – initiation of transmission when exceeding the set threshold for the parameter



―hiding‖– accumulation of video information without transmitting over the communication channel

1.3 Features



ITU-T H.263+ support



Built-in phone modem (only for «OKO-M» model)



Built-in time/real time clock



Autodial and password protected access



Adaptation to parameters of the image and communication channel



Automatic control of image quality (rate control)



Remote control over all the modes and parameters through the communication channel (each

video channel is controlled independently)



Electronic zoom, scissoring and centering of the transmitted image (Zoom/Cut/Pan)



"Behavior" programming: active and passive mode of connection establishment, including: at

changing parameters of image, at onset of scheduled event/time moment, by sensor alarm, in

case of communication disturbance.



Possibility of long-run off-line operation in case of unsuccessful attempt to establish

communication (when using one video channel it is possible to accumulate up to 700 snapshots

with resolution of 128 x 96 pixels, or 30 minutes video clip).
