1. During outdoor installation, it is strictly prohibited to aim the camera at the sun or luminous objects with strong light source. The supplementary provisions will cause image blur or halo.
2. Do not let the camera get wet or use it in wet places.
3. Do not use the camera when the temperature, humidity or power specifications are exceeded.

4. Connection mode: except (av220v).

(1) After the polarity of DC 12V power supply is clear, connect it.
(2) The formula for calculating the maximum cable length between the camera and the power cord.

Video cable:

a: 75 Ω coaxial cable is used.
b: The length of the same cable between the surveillance engineering camera and the monitor varies from manufacturer to manufacturer. If the maximum length is adopted, please verify the video quality before the final installation.

c: Precautions during wiring:

(1) Do not twist the same cable into a curve with a radius less than 10 times the cable diameter.
(2) Do not use the clip cable, even the round nail, otherwise it will cause error.
(3) Do not overstock or tighten the cable, otherwise the impedance of the cable will change and reduce the image quality.
For the judgment of image interference, please refer to the following table:

Interference phenomenon.
There is "snowflake" on the random signal-to-noise ratio image.
Longitudinal, oblique, herringbone or wavy stripes in a single interference image, namely "Reticulation".
The horizontal bar between black and white moving up and down in the power interference image, namely "black and white raceway".
The pulse interferes with irregular flicker, black-and-white pockmarks or "jumping" in the image.
Monitoring project: if the image has the phenomenon described in the above table, find the cause and take measures to avoid or compensate.
