wiring.
Make sure if the camera power adapter meets the camera operating voltage requirement
before powering up the device (The material and length of the power cable might influence
the device voltage).
Prevent the power cable from being trampled or pressed, especially the plug, power socket
and the junction extruded from the device.
We assume no liability or responsibility for all the fires or electrical shock caused by
improper handling or installation.
Environment
Do not aim the device at strong light to focus, such as lamp light and sun light.
Transport, use and store the device within the range of allowed humidity and temperature.
Keep the camera away from water or other liquid to avoid damages to the internal
components.
Keep sound ventilation to avoid heat accumulation.
Heavy stress, violent vibration or water splash are not allowed during transportation,
storage and installation.
Pack the device with standard factory packaging or the equivalent material when
transporting the device.
It is recommended to use the device together with lightning arrester to improve lightning
protection effect.
It is recommended to ground the device to enhance reliability.
It is recommended to use qualified video transmission cable to improve video quality. It is
recommended to use RG59 coaxial cable or higher standard.
Use standard components or accessories provided by manufacturer and make sure the
device is installed and maintained by professional engineers.

Important Safeguards and Warnings IV
The surface of the image sensor should not be exposed to laser beam radiation in an
environment where a laser beam device is used.
Do not provide two or more power supply sources for the device; otherwise it might
damage the device.
When the camera is in the condition of PoC power supply, do not connect any other device
between the camera and PoC transceiver including UTC, Balun, optical transceiver,
distributor and convertor and so on; otherwise, the device might get burned.

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.
Excellent low-light performance with IR or night vision technology.
Configuring devices easily with OSD menu.
Support switching between HD and SD outputs.

Maintenance 12
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.
