Appendix Ⅱ: The Cleaning of Clear Down Cover
To obtain constant clear videos, user should clean the down
cover periodically.
Be cautious when cleaning. Hold the down cover ring only to
avoid direct touch to the acrylic down cover. The acid sweat
mark of fingerprint will corrode the coating of down cover and
scratch on down cover will cause vague images.
Use soft dry cloth or the substitute to clean the inner and outer
surfaces.
For hard contamination, use neutral detergent. Any cleanser
for high grade furniture is applicable.

Appendix Ⅲ: RS485 Bus Basic Knowledge
1. Characteristics of RS485 Bus
As specified by RS485 standards, RS485 Bus is of half-
duplexed data transmission cables with characteristic imped-
ance as 120 Ω. The maximum load capacity is 32 unit loads
(including main controller and controlled equipment).
2. Transmission distances of RS485 Bus
W hen user selects the 0.56mm (24AW G) twisted pair wires
as data transmission cable, the maximum theoretical transmit-
ting distances are as follows:
Baud Rate
Maximum Transmitting Distance
2400BPS
1800m
4800BPS
1200m
9600BPS
800m
If user selects thinner cables, or installs the dome in an envi-
ronment with strong electromagnetic interference, or connects
lots of equipment to the RS485 Bus, the maximum transmitting
distance will be decreased. To increase the maximum transmit-
ting distance, do the contrary.
3. Connection and termination resistor
The RS485 standards require a daisy-chain connection be-
tween the equipment. There must be termination resistors with
120¦ёimpedance at both ends of the connection (refer to Pic-
ture 40).
Please refer to Picture 41 for simple connection. “D”hould not
exceed 7m.
The connection of 120 Ω termination resistor:
The termination resistor is ready on the Protocol PCB. There
are two kinds of connection. Refer to the Protocol PCB jumper
setting form (refer to Picture 42,43).
1)
In the Picture it is the factory default connection. The jumper is
seated on Pin2&Pin3 and the termination resistor is not
connected.
2)
when connecting the 120 Ω temination resistor, user should
pull out the protocol PCB and plug the jumper on Pin1&Pin2.
Install the PCB back and the termination resistor is connected.

4. Problems in practical connection
In some circumstances user adopts a star configuration in
practical connection. The termination resistors must be con-
nected to the two equipment that are farthest away from each
other, such as equipment 1# and 15# in Picture 44. As the star
In such circumstances the factory recommends the usage of
DR-HB16 RS485 distributor. The distributor can change the
star configuration connection to the mode of connection stipu-
lated in the RS485 standards. The new connection achieves
reliable data transmission (refer to Picture 45).
configuration is not in conformity with the requirements of
RS485 standards, problems such as signal reflections, lower
anti-interference performance arise when the cables are long
in the connection. The reliability of control signals is decreased
with the phenomena that the dome does not respond to or just
responds at intervals to the controller, or does continuous
operation without stop ( refer to Picture 44).
