2.3 Wiring and Installation
There are several ways to install the speed dome. The wall mounting is taken as an example below.
2.3.1 Wiring
The survey of the actual installation environment and planning the wiring is highly recommended
before the accurate deployment of the wire is implemented in order to provide a safe and steady
power supply and a reasonable wiring route.
Get familiar with the installation environment before deploying the wire, including the wiring
distance, surrounding, and electromagnetic interference and so on.
Please choose the cable with nominal voltage higher than the actual voltage, to ensure a
normal running in case of unsteady voltage.
To protect the power cable and the signal transmitting cable from human tampering, you
should pay attention to the protection and reinforcement of the cables.
When deploying the wire, please do not tighten the wire or make the wire loose.
The wiring of the speed dome should be performed by professionals.
2.3.2 Installing the Bracket
Before you start:

Installation Manual of HD-TVI Speed Dome

Wall mounting is applicable to the indoor/outdoor solid wall construction. The followings are the
mandatory precondition for wall mounting:
The wall must be thick enough to install the expansion screws.
Please make sure that the wall is strong enough to withstand more than 8 times the weight of
the dome and the mount.
Steps:
1. Check whether the type of the bracket and the number of accessories are right, as shown in the
figure below.
Figure 2-5 Wall Mount Bracket, Nuts and Flat Washers
2. Drill 4 screw holes in the wall according to the holes of the mount, and then insert M8
expansion screws (not supplied) into the mounting holes.
Figure 2-6 Drill Mounting Holes
3. Attach the wall mount to the wall by aligning the 4 screw holes of the mount with expansion
screws on the wall.
4. Secure the wall mount with 4 hex nuts and washers.
Figure 2-7 Secure the Mount
5. Install the speed dome to the mount. Please refer to Section 2.3.4 Installing the Speed Dome for
installation details.
Follow the same instructions described above for the short-arm wall mounting. For outdoor

Installation Manual of HD-TVI Speed Dome
12
applications, please adopt the water-proof measures. The short-arm wall mount is not
recommended for outdoor applications.
2.3.3 Set the DIP Switch
Set the DIP Set the address and baudrate for the analog speed dome. The default value of DIP
switch is shown below:
Address: 0
Baudrate:2400
Terminal Resistor: OFF
Please refer to the Section 2.2 DIP Switch Settings for DIP switch settings.
2.3.4 Installing the Speed Dome
The sketched of installing the speed dome are for reference only.
Steps:
1. Hang the safety rope to the speed dome and then hook to the mount as shown in Figure 2-8.

Appendix
Appendix 1 Lightning & Surge Protection
This product adopts TVS plate lightning protection technology to avoid damage caused by pulse
signal that is below 3000W, like instantaneous lighting stroke, surging, etc. According to the actual
outdoor situation, necessary protection measures must be taken, besides ensuring the electrical
safety.
The distance between signal transmission wires and High-voltage equipment or high-voltage
cable is at least 50m.
Outdoor wiring should better be routed under eaves as much as possible.
In the open field, wiring should be buried underground in sealed steel pipe, and the steel-pipe
should be one-point grounding. Overhead routing method is forbidden.
In strong thunderstorm area or high induction voltage areas (such as high-voltage transformer
substation), high power lightning protection apparatus and lightning conductor are necessary to
be added.
The design of lightning protection and grounding of the outdoor devices and cables should be
considered together with the lightning protection demand of buildings. It also must conform to
the related national standards and industrial standards.
The system should be equipotential grounded. The grounding equipment must conform to the
demands of system anti-jamming and electrical safety both and it must not appear short circuit
or mixed circuit with the zero conductor of strong grid. When the system is grounded alone, the
resistance should be no more than 4Ω. The sectional area of the grounding cable should be no
less than 25mm2. For grounding instructions, please refer to the Installation Manual of Speed
Dome.

The speed dome must be

Appendix 2 RS485 Bus Connection
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).
RS485 Bus Transmission Distance
When using 0.56mm (24AWG) twisted-pair line, according to different baudrate, the maximum
transmission distance theory table is shown as below:
Table A-1 Max. Distance of RS485 Transmission
Baudrate
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.
Connection Methods
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.

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

For such case, the best way is adding a RS485 distributor. This product can effectively change the

avoid those problems and improve the communication reliability. Show as figure 5.

Appendix 3 24VAC Wire Gauge & Transmission Distance
The following table describes the recommended Max. distance adopted for the certain wire gauge
when the loss rate of 24VAC voltage is less than 10%. For the AC driven device, the maximum
voltage loss rate is 10% allowable. 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 0.8000mm is required as
the minimum wire gauge.
