on-off devices, such as stepper motors. In particularly, do not route power cord and network cable

with such devices in parallel because such devices have strong electro-magnetic radiation which is

easy to couple to the camera's transmission line.



Shelter grounds of all devices must be connected together and take single point grounding.

Multi-point grounding easily leads to voltage difference between devices which form circuits to

induce couple electro-magnetic interference.



Power supply for camera and that for PC must be from the same AC power distributor in order to

connect their shelter grounds and avoid multi-point grounding. High-power mechanical and

electrical equipment do not directly use this AC power.



Magnetic ring can be added to the power control cord of camera in order to absorb

electro-magnetic interference signals.



Please keep the suitable humidity and operate with wrist strap, anti-static clothes and shoes to

reduce ESD.

3.1.2.2 Heat Dissipation

Under the condition of a stable condition(temperature and humidity, air flow, installation location,

etc.)the camera will reach a temperature balance in 1 or 1.5 hours, which means that the cover

temperature will not rise any longer. It is important to ensure the cover temperature beyond 50℃ and

there is a temperature difference of 25℃ between inner main heat source and outside cover in this

balanced condition. When the cover temperature is under 50℃, the electronic chip inside will not suffer

damage.

Recommend several good methods of controlling the temperature：



Ambient temperature should be beyond 30℃, it is best to work in an air-conditioned environment.



Installed on the object with good thermal conductivity, such as large metal which is easy to

dissipate heat.



Ensure certain air flow to dissipate heat.
