### Image sensors (either **CCD** or **CMOS** sensor technology)
* frame rates
* resolution
* pixel size
* power consumption
* quantum efficiency
* FoV (Field of View)
### Sensor Interfaces
* MIPI CSI (1/2/3)
* FPD-Link
* GMSL
### Processor (SoC/DSP/FPGA, Signal processing engines)
* Intel Movidius
* NVIDIA Jetson SoMs
* NXP i.MX 8 Series Applications Processors
* Qualcomm APQ/QCS application processors
* Xilinx Zynq UltraSCALE+
* Arm RISC processor cores 
* Microchip
* Lattice Semiconductor, etc. 
### Camera interfaces
* USB 3.2
* CoaXPress 2.0
* Thunderbolt3
* DCAM
* CameraLink HS (Framegrabber)
* Gigabit Ethernet

### System Software

* Operating System: Linux rules the embedded world 
* Sensor drivers: clock frequencies, frame size, frame interval, signal transmission, stream controls, sensor power management and sensor control framework 
* OpenCV: computer vision library has become the most popular image processing platform 
* Algorithms
* AI and ML: providing intelligence at the edge

### Key performance and feature considerations
* HD / 4K Video Streaming: massive amount of data generated need to be transmitted to a remote location with minimal latency
* Video compression: MJPEG, MPEG-4, H.263, H.264, H.265, and H.265+
* Video streaming protocols
    * Real-Time Streaming Protocol (RTSP): ==low-latency streaming==
    * Real-time Transport Protocol (RTP)
    * RTP Control Protocol (RTCP)

* Small form-factor, low-power design
    * PoE for wired camera designs ensures that the camera is always powered and connected
        * 802.3af (PoE) can deliver 15.4 watts over Cat5 cables.
        * 802.3at (PoE+) can deliver up to 30 watts over Cat 5 cables with 25.5 watts available to devices.
* Cloud integration
    * Hardware for data storage and computing systems
    * Cloud offers an easy and affordable solution, enabling users to store and access the data anytime, anywhere
