Preface
The DVTel 9840 Series of Internet Protocol (IP) Pan-Tilt-Zoom (PTZ) Domes feature a
variety of PAL and NTSC models for both indoor and outdoor use.
The domes contain a built-in MPEG-4 encoder that converts analog video into one or two
MPEG-4 streams. The latter option is used to support viewing and recording at different
qualities (up to 4CIF, 30 ips NTSC or 25 ips PAL). The domes are powered using 24 VAC
current, delivered either through a Power over Ethernet (PoE) wiring accessory or directly.
PoE is not available for outdoor domes. Each dome also contains DIP switches for setting
the PTZ number, baud rate and protocol.
The DVTel Domes are designed to integrate seamlessly with Latitude NVMS. Most of the
devices’ configuration is typically performed through the Latitude AdminCenter.
Dome setup involves three principal tasks: encoder configuration, physical installation and
camera configuration.
The diagram below shows the dome’s dimensions, in millimeters.
