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 DCAM560C 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 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 observe the
maximum and minimum housing temperatures in Section 3.1

3.5 Optical Specifications
3.5.1 Field of View
The field of view refers to the view angle of the ToF products. The TOF sensor’s aspect
ratio is 4:3, typically the horizontal field of view is larger than the vertical field of view.
The DFOV (see figure below) is the angle subtended by the diagonal of the camera
sensor onto the center of the lens.
The definition of HFOV and VFOV can be exchanged, i. e. we can rotate the camera
sensor to have larger FOV at vertical direction.
Typical FOV of DCAM560C Series is 69°*51°, we can do FOV customization if the
customer requires, and reasonable NRE fee shall be charged.
3.5.2 Wavelength of the VCSEL
All our product are based on VCSEL laser. We have variety choices according to the
lens FOV and wavelength. The laser FOV must match to the lens FOV, and the wider
FOV products need stronger power, therefore higher power consumption. Even with
higher power supplied, the laser power per angle of the wider FOV product may be
reduced, so normally the maximum distance of wider FOV products is shorter than
narrower FOV products.
As for the wavelength, we have 850nm and 940nm laser selection. Because of the
silicon process based ToF sensor, the ToF sensor’s QE of 850nm is much better than
it of 940nm. That means normally 850nm product can reach longer distance or the
same distance with lower power consumption;
But the 940nm wavelength has better performance under strong sunlight, especially
when the ambient light is stronger than 20K LUX.
Below are the laser choices we can provide, if you have other needs, please let us
know.
H69°, V51°--- 2W, 940nm
H110°, V85°--- 2W, 850nm

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

14
provide an air flow over the camera.
3.6.4 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.
Fig. 3.3: Origin of the Coordinate System
The origin of the coordinate system is defined as the below figure shows:
1. X coordinate is zero at the X direction axis line of the camera housing;
2. Y coordinate is 9.75mm offset from the Y direction axis line of the camera housing;
3. Z coordinate is zero offset at the front of the camera housing;
Meshlab and CloudCompare tools are recommended to analyze the point cloud data

15
saved by Vzense software or SDK method.

Hardware Trigger Function
Hardware trigger mode is available only when the camera works at slave mode, in
slave mode the camera will wait for the hardware trigger signal on Ext_Trigger.
The EXT_Trigger signal is to driver the MOSFET, External input trigger signal voltage
should range 3.3V-20V, driving current ability should be more than 5mA;
You can use input pin Ext_Trigger to send a hardware trigger signal to the camera. The
hardware trigger can be used to trigger the acquisition start. A hardware debouncer
circuit shall be considered on the EXT_Trigger line.
By default, the hardware trigger is rising edge activated, refer to below exposure

Exposure_timing Pin Description
This pin is an output indicates the whole exposure period of the camera. The internal
circuit of this pin with a pull-up resistor 430Ω.The pull up voltage is 5V. At low level,
the pull-down resistor is 100Ω.
By default, the polarity is low level activated, which means a low-level signal indicates
the exposure period. Please refer to below figure:
