M75362 ceiling cameras and M75692, M75761 compact cameras are connected to the popular 4-channel DVR Hikvision M75605, with the use of typical CCTV cable Camset/YAR M5995. The cable transmits the baseband video signals (via its RG59 component) and supplies power to cameras (via two 0.5 mm power wires). The power is distributed from the M1825 power supply unit via power supply distributor M1802. Good practice requires protection of low-current systems against overvoltages. This function is performed by the Video Surge Protector HDO-1F PRO (BNC) M17011. It is worth mentioning that modern CCTV DVRs make use of smartphones. The users can remotely configure the DVRs and view images from the cameras.
- know the differences between different types of analog cameras
- select the appropriate camera type to working conditions

- design power circuits for analog CCTV cameras
- select a suitable DVR and configure it appropriately to the needs
- calculate the necessary disk space depending on the recording parameters
- remotely configure DVRs, using available applications for Windows systems and smartphones
- classify TV modulators due to the type of the output signal
- distinguish the spectrum of analog PAL and digital DVB-T (COFDM) signals
- know the rules for determining the optimum output levels of selected active components of RF distribution systems (amplifiers, modulators)
- Select the suitable router and switch
- Mount the network devices in a RACK cabinet
- Install RJ-45 connectors
- Physically connect the network devices
- Configure the network
- Diagnose network failures
