1.1 General
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 like financial center, telecom site, supermarket, hotel,
government, school and factory.
1.2 Features
720p series support over 800 meter real-time transmission of video and control signal from
RG59 cable; for 1080p to 4k series, the distance is 500 meter.
Excellent low-light performance with IR or night vision technology.

Find the mounting template sticker from the accessory pack and stick it to the mountingStep 1 surface①
Drill screw holes (and the cable outlet hole if it needs to go through the mountingStep 2 surface) on the mounting surface as indicated on the mounting template, then insert
expansion bolts②from the accessory pack in the screw holes.
The disassembly way of model A is different from which of model B and model C.Step 3
For modelA, hold the pedestal③tightly and keep the device⑤upward, rotate the
fixing ring⑦counterclockwise until you can detach it from above, and then take off
the pedestal③.
For model B and model C, loosen the locking screw⑨with the supplied wrench⑧
and take the pedestal③off.
Adjust the location of the pedestal③according to cable outlet requirement (top out orStep 4 side out), then pull the cable out through mounting surface or the side cable tray. Align
the screw holes on the pedestal③to those on the mounting surface, then put in and
fasten the supplied self-tapping screws④to attach the device⑤to the mounting
surface.
Connect the camera to power source and the XVR device, and the live view screen willStep 5 be displayed.
The assembly and adjustment way of model A is different from which of model B andStep 6 model C.
For model A, put the fixing ring⑦back to hold the enclosure⑥, leave some
spaces enough for you to adjust the device⑤. Aim the lens to the ideal angle (see
Figure 3-3) and fasten the fixing ring⑦.

For model B and model C, put the enclosure⑥back on and adjust the locking
screw⑨to hold it, leave some spaces enough for you to adjust the device⑤. Aim
the lens to the ideal angle and adjust the focus until you get clear image (see
Figure 3-4) and fasten the locking screw⑨.

For model B and model C, it is easier to fit the enclosure⑥to the pedestal③if you put the
higher end in first and then the lower end.
For the models with vari-focal lens, you can adjust the zoom and focus through XVR
device.

Maintenance 13
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.
