SETUP PROCEDURE 

Installing the Polycom® HDX 4500 system was  straight forward. The Quick Start 
Guide clearly illustrated this simple procedure: 
 

 

Connect the control panel to the unit.  

 

 

Connect the RJ45-RJ45 cable to establish an Ethernet IP network connection 

 

 

 

 Connect mains power to the unit.   

 

System set up was also  convenient and trouble free.  The IP address,  IP Gateway, 
Subnet  mask  and  Gatekeeper  address  were  all  configured  by  the  control  panel 
through the on screen menus. 
 
  
Approximate set-up time: 

15 minutes 

 

 
Documentation quality: 

The  documentation  was  concise  and  easy  to  follow 
and  included:  Setup,  Quick  Start,  User‘s  and 
Administrator guides.

HARDWARE DESCRIPTION 

 

HDX 4500 System 

The HDX 4500 systems supplied for evaluation had a maximum call bandwidth of 
4 Mbit/s and included the 1080p (30fps) option.  
 
The CODEC offers several video resolutions including: 
 

 

SIF 

352 x 240 pixels 

 

CIF  

352 x 288 pixels 

 

2CIF 

704 x 288 pixels 

 

4CIF 

704 x 576 pixels 

 

High definition w720p   i.e. 1280 x 720  @ 60 frames per second 

 

High definition w1080p i.e. 1920 x 1080 @ 30 frames per second 

 

The  image  resolution  and  frame  rate  are  dependent  on  the  call  connection 
bandwidth  and  the  video  mode  (Motion  or  Sharpness),  the  default  setting  being 
Sharpness:
