2.4 DIP Switch Setup

2.4.1 DIP Switch Location and Function

The corresponding functions between analog speed dome and HDCVI speed dome are different,
which will be separately introduced below.

2.4.1.1 Analog Speed Dome

It is to take ceiling mount speed dome for example. Open the transparent cover of the device and
you can see there are two DIP switches on the PTZ, which are used to set speed dome address,
baud rate and parity. The location of DIP switch is shown in Figure 2-2.

Figure 2-2

2.4.1.2 HDCVI Speed Dome

It is to take ceiling mount speed dome for example. Open the transparent cover of the device and
you can see there are two DIP switches on the PTZ, which are used to set speed dome address,
baud rate. The location of DIP switch is shown in Figure 2-3.
