Architecture and Terms

Our software is built on the standard LAMP (Linux, Apache, MYSQL, and PHP) architecture. The software has been designed to work on the latest LTS version of Ubuntu Linux. For networking purposes, there are 2 main components to the software application:

Application Server: This makes up the bulk of the application and consists of 3 primary components:

  • PHP web pages being served up by the Apache web server
  • MySQL Database
  • NodeJS messaging and control service

Media Server: This portion of the application handles all the communication with the cameras and video streams being served out to the client PCs. It also handles all the recording and clip creation.

From a physical or virtual server perspective, the entire server side software stack can be run on a single server. For applications requiring more than 50 cameras or consisting of different departments the software can be broken out and additional Media Servers can be added. These servers only run the Media Server portion of the VALT application.

Digital Wowza License

Only required for servers utilizing an electronic Wowza key. Servers with a physical Wowza key do not need access to the licensing servers.


This communication is required to verify valid Wowza Streaming licenses.

VALT Cloud

VALT Cloud is a hybrid solution that requires an on-premise server and a cloud server.

The cloud server is the Application Server. This hosts the website where users will access the application.

The on-premise server is a Media Server. This hosts the camera streams and recordings.


The on premise media server will establish a connection to the VALT AWS Private Cloud. All traffic will flow through this connection. This connection requires the following ports:

On-Premise Media Server to Cloud Application Server
Port Source Destination
UDP 500 On-Premise Media Server Cloud Application Server
UDP 4500 On-Premise Media Server Cloud Application Server
GRE On-Premise Media Server Cloud Application Server

VALT Cloud utilizes Let's Encrypt to provide SSL certificates. The On-Premise Media Server must be able to communicate with the following websites to request the certificate:

Let's Encrypt
Port Protocol Source Destination
TCP 443 HTTPS On Premise Media Server https://acme-v02.api.letsencrypt.org
TCP 443 HTTPS On Premise Media Server https://route53.amazonaws.com
