Introduction 1
1 Introduction
General1.1
This series of products comply with the HDCVI standard and support the transmission of video
and control signal over coaxial cable. They produce video signal with megapixel resolution and
require XVR device that comply with the HDCVI standard to achieve high speed, long distance,
and zero lag transmission of the signal. They are applicable to cover the high definition
monitoring needs for locations with low ambient light, including road, warehouse, underground
parking lot, bar, pipeline, and gas station.
Features1.2
720p series support over 800 meter real-time transmission of video and control signal from
RG59 cable; for 1080p and above, the distance is 500 meter.
Support adjusting zoom and focus on XVR with motorized varifocal lens (available on
select model).
Excellent low-light performance with IR or night vision technology.
Configuring devices easily with OSD menu.
Support switching between HD and SD outputs.

Maintenance 11
5 Maintenance
In order to maintain the image quality and proper functioning of the device, please read the
following maintenance instructions carefully and hold rigid adherence.
Disassembly and Desiccant Replacement
Carefully follow the instructions in the manual when performing any disassembly operation
about the device; otherwise, it might cause water leakage or poor image quality due to
unprofessional disassemble.
Please contact after-sale service for desiccant replacement if there is condensed fog found
on the lens after unpacking or when the desiccant turns green. (Not all models are included
with the desiccant).
Maintaining Lens and Mirror Surface
The lens and mirror surface are covered with antireflection coating, which could be
contaminated or damaged and result in lens scratches or haze image when being touched
with dust, grease, fingerprints and other similar substances.
Do not touch the image sensor directly (CCD or CMOS). Dust and dirt could be removed
with air blower, or you can wipe the lens gently with soft cloth that moistened with alcohol.
Maintaining Device Body
Device body can be cleaned with soft dry cloth, which can also be used to remove
stubborn stains when moistened with mild detergent.
To avoid possible damage on device body coating which could cause performance
decrease, do not use volatile solvent such as alcohol, benzene, diluent and so on to clean
the device body, nor can strong, abrasive detergent be used.
Maintaining Dome Cover
Dome cover is an optical component, do not touch or wipe the cover with your hands directly
during installation or operation. The following approaches can be used to deal with possible
contamination.
Removing Dust
Wipe gently with non-oil soft brush or use air blower.
Removing Grease or Fingerprints
Wipe the cover gently with soft cloth to make it day, then moisten oil-free soft cloth or lens
cleaning paper with alcohol or lens cleaner and wipe the cover gently. You may perform
repeatedly until the cover is clean.
