9.2 System Planning
Based on the survey above, you can get started with a comprehensive system design plan and select appropriate
cameras, back-end hardware and software for your customers now.
9.2.1 Camera Considerations

as day and night, resolution (Megapixel or VGA), cabling (PoE or wireless) and compression formats (MJPEG,
MPEG-4 or H.264) or other alternatives will also be main considerations for identifying an exact network camera.
9.2.2 Hardware Considerations
Computer
PC hardware requirements must be higher than 1.7GHz processor and 256MB memory. Free-bundled software
has to be run on Microsoft Windows 2000/XP/Vista.
PoE Switch/Wireless Access Point
PoE switches must be deployed if you are installing PoE-enabled cameras. For wireless connection, you need to
prepare a wireless access point.
NVR
You can have an NVR as a dedicated storage device so as to prevent surveillance video data from sharing the
storage space of PCs.
9.2.3 Software Considerations
Internet Browser
Internet Explorer 6.0 or above and Mozilla Firefox must be installed so as to view video images on PCs. For cellular
phone, 3GPP player is required.
Central Management Software
For a video surveillance system, viewing, recording, playing back, and managing videos are basic functionalities.
VIVOTEK offers reliable free-bundled 32-CH ST7501 central management software to meet your various
requirements.
Other Software
Besides central management software, many customers expect to have more advanced functions such as
intelligent analytics for a variety of applications. VIVOTEK has been working closely with numbers of well-known
softwarepartnersasourSIA(SoftwareIntegrationAlliance).Foranyspecicneed,youmaycheckoutourwebsite
