2 Installing exacqVision Software on Third-Party Clients and Servers

Server Requirements

Hardware Requirements

See the Exacq website at https://www.exacq.com/products/vms_requirements.html for current minimum hardware

requirements. Actual hardware requirements vary considerably based on each user’s application:

 CPU requirements increase greatly when hosting multiple concurrent web clients.

 The exacqVision server application requires a maximum of 4GB, although additional memory is required for the

operating system, web hosting, or any other server applications.

 The storage system is often the performance limitation because of the large amount of read and write

processes. Your storage system should be capable of sustained reads/writes at least twice the maximum data

rate from all cameras. Exacq highly recommends using RAID 5 or RAID 6 for all video storage to reduce the

likelihood of catastrophic failure.

 Enterprise-grade hard drives are highly recommended to handle constant video recording.

 The server operating system and exacqVision software should be installed on a dedicated, mirrored operating

system drive.

 Servers should always be UPS-powered to avoid data corruption during power failure.

Operating System Requirements

See the Exacq website for minimum operating system requirements. In addition:

 If automatic updating is enabled, your server might stop recording video when the operating-system restarts.

 Anti-virus programs should scan only the operating system and exacqVision software drives. Virus scanning

should be disabled on all video storage drives to avoid large decreases in drive performance.

 Port blocking is not recommended because many edge devices use multiple or dynamic port assignment.

MAC addressing requirements

exacqVision software is licensed based on MAC addressing. Servers with teamed NICs or other arrangements that

obscure the MAC require an additional USB-based NIC to provide a licensing MAC.

Networking

For the greatest system reliability and performance, the network administrator should observe the following best

practices:

 A dedicated VLAN and NIC port for all cameras.

 A dedicated VLAN and NIC port for storage networks (if used).

 A separate VLAN and NIC for all client connections.

 Cameras and servers should use fixed IP addresses. Clients can use DHCP.

 Camera-to-server network capacity should be twice to maximum video data rate.

 Server-to-thick-client network capacity should be 1.5 times the maximum total data rate of all simultaneously

viewed cameras.
