1.2 Description and Features
Vzense TOF RGBD Camera Module DCAM305 is a 3D camera module developed by
Vzense which uses TOF (Time of Flight) technology for face application scenarios or
short distance scenarios. It is packaged in a small form factor and can provide high-
precision depth information to be widely used for face-related applications such as
financial payment, access control, gates, smart lock, time attendance terminal, etc.
DCAM305 comeswith Vzense DepthCamera SDK, an opensource and cross platform
enabling suite including rappers, sample code and tools.
DCAM305 Features:
- TOF (Time of flight) Camera technology

- Time Attendance Terminal
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 DCAM305 camera can be powered by standard USB Micro USB.
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.
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

Storage temperature:
Storage humidity:
-20–50 °C
20–80%, relative
-30–70 °C
20–80 %, relative
Heat Dissipation
Users can provide sufficient heat dissipation, like mounting the camera on a substantial,
thermally conductive component that can act as a heat sink. Or a fan can be used to
provide an air flow over the camera.
3.5.4 Coordinate of the Camera System
There are two coordinate system need to be understood, one is camera coordinate
system (CCS), one is world coordinate system (WCS).
CCS: CCS describe the two-dimensional data; the origin of coordinates is the optic
center.
WCS: WCS describe the three-dimensional information.
The CCS data can switch to the WCS data using the camera internal parameters.
