Preset Point Function
These cameras can be set to handle up to 64 preset positions. Any one position can be called up at any time. The
built-in image stabilizer compensates for vibrations and fluctuations caused by the camera's movement.
Alarm Input Function
These cameras can option with four alarm inputs. Alarm signals will activate the camera to automatic on preset point
corresponding to the alarm received.
SAFETY PRECAUTIONS
1. Select a proper location and use safe hoist for installing speed dome cameras.
2. Confirm that the hoist is capable of lifting to the installation position.
3. Proper protective measures must be provided in the hoist, for protecting engineering staffs.
4. Confirm that power supply is 24V AC. Ensure safety precautions for preventing electric shock.
PRECAUTIONS ON INSTALLATION
1. Basic requirements for installation
Follow local regulations about installation safety request.
Check out if accessories are complete. Optional accessories are required for different installation sites. Please contact your
local distributors for proper installation accessories, so that the camera could be installed safely without causing danger.
Check if the installation location is of sufficient height.
Check if the installation location is strong enough for supporting cameras. Make sure installation spots (ceiling or wall) is of
sufficient strength to support the camera and bracket without immediate danger of falling.
2. Cable standards
Coaxial cable for image signal:
Select proper cable length for your installation distance. Recommended spec. is as follows:
a. RG59/U:
b. RG61/U:
c. RG11/U:
3. RS485 Cable
Please comply with RS485 wiring standards and select proper RS485 cable. Improper cable may result in RS485
communication transmission error, which may cause speed dome cameras to react incorrectly. Please pay much attention to
this prior to installation.
When thinner or lower anti-interference RS485 cable is used for connecting the camera, the maximum transmission distance
may be shortened and vice versa.
Standard rule for RS485 transmission distance:
When using 20AWG (Belden 8760) Shielded Twisted Pair Cable, different control Baud Rate will have different
transmission distance performance, see table:
Baud rate
2400
4800
9600
4. Remove protection materials
Remove protection materials before supplying power to the camera, so as to prevent it from faulty operation or causing
mechanical errors.
