No, Kantech EntraPass cannot be installed on recorders that were purchased prior to February 9, 2016 without the CSA option.
If a server was previously ordered with the CSA upgrade, you can obtain the installation and registration code from Kantech technical support or from the Kantech website registration.

When Kantech EntrapassWeb is installed alongside exacqVision Webservice software running on 3rd party (COTS – Commercial Off-the-Shelf) hardware, there will be a conflict on port 80. Port 80 is the port responsible for receiving and responding to http web requests. Both exacqVision Webservice and EntrapassWeb have are configured to use this port as default.
<br>
Anyone running Kantech EntrapassWeb and exacqVision Webservice on COTS hardware will be affected by this. Note that exacq-built machines that come with Kantech onboard have already been configured to eliminate this conflict. The IIS web service on an exacq-built machine is configured for port 81.
<br>
The solution is to change the port value for Microsoft’s IIS web server to port 81. To do this follow these steps.
4.Navigate down to Default Web Site
5. Click Bindings
6. Select the http entry
7. Click Edit
8. Change Port value to 81
9. Click OK
10. Start or Restart the IIS Web Site
11. Then close the IIS Manager
Now EntrapassWeb will respond to port 81.
