Smart cameras
4 questions
What is a smart camera?
A smart camera combines image capture and image processing in the camera housing.
It can evaluate images itself and transfer results such as:
OK/NOK
position
measured value
code content
directly to the machine.
HIKROBOT, for example, offers smart cameras with integrated vision tools and communication protocols.
What is a vision sensor?
Vision sensor is a market term for compact camera-based sensors that are often simpler to configure and tailored to typical inspection tasks.
There is no hard universal technical boundary between “vision sensor” and “smart camera”.
Manufacturers use the terms differently.
What is the difference between a vision sensor and a smart camera?
Typically:
vision sensor
simpler to set up
more strongly pre-built functions
compact
sensor-like operation
smart camera
greater flexibility
more algorithms
more complex sequence control
often more capable communication
The boundaries are fluid. HIKROBOT explicitly describes its SC1000 series as combining vision functionality with sensor simplicity.
Can a smart camera communicate with a PLC?
Yes, provided the particular model supports the protocol required.
Possible interfaces are, for example:
digital I/O
TCP/IP
PROFINET
EtherNet/IP
Modbus TCP
Protocol support is product-specific.
