2.What TCP/IP ports does PelcoNet use?

PelcoNet lets you select which base port to use. The default is 25000. This means PelcoNet will use TCP ports 25000-25001 and UDP ports 25002-25011 (12 ports total) for all video and control data. The ports must be open for PelcoNet to function properly.

3.Can I view PelcoNet over the Internet?

Yes. You will need a static IP address and enough bandwidth to view live video. Pelco recommends a minimum of 250 Kbps for medium image quality. Also check with your ISP to verify the correct TCP and UDP ports are open through any routers or firewalls through which you will connect. The base ports are adjustable in PelcoNet. For example, if you choose port 25000 (default), it will use TCP ports 25000-25001 and UDP ports 25002-25011 (12 ports total) for all communication: video and control.

4.How many connections does PelcoNet support? Can more than one receiver connect to a transmitter at the same time?

Yes. PelcoNet can support an unlimited number of simultaneous connections. To do so, all hubs, switches, and routers must support multicasting (IGMP), and PelcoNet must be configured to use multicasting. If the network hardware does not support this, then the maximum number of simulta- neous connections is five.

5.Can I enlarge the picture size in the browser?

Yes. You can select from two different image sizes in PelcoNet with the browser: 288 x 352 or 576 x 704.

6.What software does PelcoNet require?

PelcoNet works with Internet Explorer 5.0 or higher. An ActiveX plug-in is also required for Internet Explorer to get live video. All software is included.

7.Can I control other manufacturers’ equipment from the browser? Not at this time.

8.Can I record video with PelcoNet?

Yes. PelcoNet can record video to the hard drive of the viewing PC. The video is recorded in AVI format, which allows playback through either the browser or Windows Media Player.
