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 absolute
specification of voltage and current.
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 model can work via 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 supply PoE+ injector as a standard product, but we can purchase it
from 3rd party and ship it to customer at original cost if needed.
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 power connector firstly before getting power source on.
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 read the
maximum and minimum housing temperatures in Section 3.1
We suggest to mount the camera on a thermally conductive material frame, for
example metal frame which can help on heat dissipation.
