Chapter 1 Installation

1.1 Check Parts List

Prior to installation, unpack the dome unit and check whether it is in good condition and all parts and accessories are included by

referring to the packing list).

Note: The power supply for the speed dome is AC24V/3A or DC12V/3.3A.

1.2 Installation 

Note: The following installation instructions are applicable to both high speed dome and network speed dome models, including the

surface mounting method.

1. Install the dome mount. Please refer to the related sections from Chapter2 to Chapter7 for specific installation methods of

different mounts.

2. Open the bubble and remove the expand aple poly ethylene and protective sticker from the dome drive. And then replace the

bubble to the dome.

3. Install the surface mounting base.

 If the dome is installed to the wooden wall, directly use the self-tapping screws to secure the mounting base to the wall.
 If the dome is installed to the cement wall, drill three Φ5 mounting holes onto the wall according to the holes locations.

And then insert the cement screws into the holes and finally use self-tapping screws to secure the mounting base to the

wall.

Appendix 1 RS485 Bus Connection

1. General Property of RS485 Bus

According to RS485 industry bus standard, RS485 is a half-duplex communication bus which has 120Ω characteristic impendence, the

maximum load ability is 32 payloads (including controller device and controlled device).

2. RS485 Bus Transmission Distance

When using 0.56mm (24AWG) twisted-pair line, according to different baud rate, the max transmission distance theory table is shown

as below:

Baud Rate Max Distance

2400BPS 1800m

4800BPS 1200m

9600BPS 800m

The transmission distance will be decreased if we use the thinner cable, or use this product under the strong electromagnetic

interference situation, or there are lots of devices are added to the bus; on the contrary, the transmission distance will be increased.

3. Connection Method and Terminal Resistance

1) RS485 industry bus standard require daisy-chain connection method between any devices, both sides have to connect a 120Ω

terminal resistance (show as Diagram 1), the simplified connection method is shown as diagram 2, but the distance of “D”

should not be too long.

Diagram 1

Diagram 2

2) Connection of 120Ω terminal resistor

The 120Ω terminal resistor can be connected through the DIP switch on the communications board, as shown in Figure3. For a new

dome, the 120Ω matching resistor is defaulted as unconnected, switch on the eighth bit of SW2, it will be connected. Conversely,

switch off the eighth bit of SW2, it will be unconnected.

4 Inch Speed Dome Installation Manual V2.0.0

Figure 3

4. Problems in the Practical Application

Normally, users adopt star-shape connection method in construction, under this situation, the terminal resistors must be connected

between two farthest devices (as Figure 4, 1# and 15#), but this connection method is not satisfy the requirement of the RS485

industry standard so that it will lead to some problems such as signal reflection, anti-jamming ability decline when the devices are

faraway. At this time, the dome will be uncontrollable, or self-running, etc.

Figure 4

For such case, the best way is adding a RS485 distributor. This product can effectively change the star-shape connection to which

satisfies the requirement of RS485 industry standard, in order to avoid those problems and improve the communication reliability.

Show as figure 5.

Appendix 2 24VAC Wire Gauge & Transmission Distance

The following table has described the recommended max. distance adopted for the certain wire gauge when the 24VAC voltage loss

rate is less than 10%. For the AC driven device, the maximum voltage loss rate allowable is 10%. For example, for a device with the

rating power of 80VA which is installed at a distance of 35 feet (10m) away from the transformer, then the minimum wire gauge

required is 0.8000mm.
