2 Precautions
2.1 Safe Usage Instructions
DANGER
Electric Shock Risk
Non-standard and improper power supplies may result in fire and electric shock.
You must confirm the camera power supply used that meets the Safety Extra Low
Voltage(SELV) and Limited Power Supply (LPS) requirements.
CAUTION
Invisible Radiation
This camera uses laser to work, improper use may damage the eye. Lasers are classified
as risk group 1 (low risk) according to EN 60825 which means that the product presents
no risk related to exposure limits under normal usage conditions. Eye safety is only
guaranteed when the camera is used properly
2.2 Power
The DCAM550-U series products can work with either USB power or external DC
power.
With USB power, the working distance will be limited by the USB host power ability.
Normally the USB2.0 host can supply up to 5V/500mA current. USB3.0 host can
supply up to 5V/900mA current. We strongly suggest to use external DC power if you
require far distance which more than 4 meters. The DC power can accept 11V~26V
power source. For higher than 26V or lower than 11V, the device shall not work well or
even be damaged.
The DCAM550-P series products can work with either Power over Ethernet or
external DC power.
For PoE power source, the PSE device shall apply the PoE+ standard (802.3at) or
above, lower than that may cause the product doesn’t work well or even be damaged.
The DC power can accept 11V~26V power source. For higher than 26V or lower than
11V, the device shall not work well or even be damaged.
Vzense doesn’t produce PoE injector, but we can purchase it from 3rd party and ship

to customer at original cost.
Below is the PoE+ injector available vendor list.

2.3 Usage
Don’t try to open the camera housing. Each camera has been calibrated at the factory
to achieve precise measurements. Touching internal components may damage the
camera and cause calibration data lost.
Incorrect plugging in and unplugging of the camera’s power cable can damage the
camera. To avoid switch-on surges damaging the camera, please plug in the power
cable into the camera’s 6-pin connector firstly before getting power supply.
Don’t try to change the position of the lens, may cause damage to the camera.
Do store the camera carefully when not in use, in original package the best.
2.4 Temperature
To avoid damaging the camera and to achieve best performance, please observe the
maximum and minimum housing temperatures in Section 3.1
