ADPRO FastTx
An ADPRO FastTx system consists of one or more Multi-Site Video Security Systems at remote
sites and a PC running the ADPRO VideoCentral software at a monitoring site. Connection is via
a TCP/IP based Ethernet network, dial-up, leased telephone lines or ISDN.
Function
Description
Video inputs
Model AFTX-10 = 10 video inputs, Model AFTX-20 = 20 video inputs,
1 volt p/p video input, 75 ohm or high impedance, selectable via menu.
Colour / Monochrome Operation
Colour or monochrome. Default operation is for colour. Individual channels can be
selected as monochrome (B&W).
Video output
1 BNC composite video output designed to drive a 75-ohm load.
Video standard
Either PAL or NTSC (switch selectable).
Colourburst lock range
PAL 4.433619 MHz ± 230 Hz
NTSC 3.579545 MHZ ± 179 Hz
Grey Scale Resolution
256.
Video Compression Engine
(VCE)
AFTX-10 = 1 VCE module
AFTX-20 = 2 VCE modules
Image compression is via customised H.263 compression algorithm resulting in an
average of 3 KB per images at CIF resolution picture quality 6 and 6KB per image
at 2 CIF resolution picture quality 7.
Video Display modes at video
output
Full screen spot or sequence monitoring.
Image transmission rate
Typical transmission rates (subject to amount of scene activity):
Ethernet: 25 images per second
ISDN: 128 kbps = 12.5 images per second
PSTN 33.6 kbps = 3 images per second
Alarm inputs
Model AFTX-10: 20 alarm contact sensing or logic level inputs.
Model AFTX-20: 30 alarm contact sensing or logic level inputs.
Programmable to trigger an alarm on contact opening or closure.
All inputs have impedance >1 K ohm and transient protection >20 KV.
Single End-of-Line (SEOL) or Dual End-of-Line (DEOL) tamper detection on each
input.
Screw terminal connectors.
Voltage input less than 0.8 V = logic low, 7 mA (maximum).
Voltage input between 3.5 V and 5.0 V = logic high.
Minimum alarm contact duration = 100 milliseconds
Activity Detect Zones
The maximum activity detection area is defined by the number of available
detection zones:
396 zones (22 wide x 18 high) using CIF PAL resolution (352 x 288 pixels)
330 zones (22 wide x 15 high) using CIF NTSC resolution (352 x 240 pixels)
A detection zone represents a screen area of 16 x 16 pixels.
