The system watches the hardware of a video surveillance network around the clock — switches, cameras, radars, servers and storage — and shows in one panel what works, what is degrading and what is down. The operator sees the problem and gets an alert before the call "the camera is not recording" arrives. It runs inside the closed network of the site: no internet access, and nothing is installed on the cameras or switches themselves.
Availability and uptime, the state and link speed of every port, traffic and CRC errors, VLANs, neighbouring devices, the MAC address table. The front panel is drawn with the real port layout, and configuration history is kept.
Whether the camera is reachable, whether the video stream is running and whether the management service answers. A dropped stream on a live camera is a separate alarm: "online but not recording".
CPU and memory load, disk usage, service state, RAID arrays and disk health via SMART — a warning about a disk before it fails.
Two independent states: the link to the device and the calibration deadline. An expired calibration means legally invalid measurements, so it is tracked separately.
The system polls the switches, collects their neighbours over CDP and LLDP and draws the links between devices. Nobody has to draw the diagram by hand or keep it up to date: the map is rebuilt on demand and shows how the network is actually wired, not how it was planned on paper.
✔ The practical gain: when a camera stops answering you can see which port of which switch it is plugged into — no walking to the rack to trace the cable.
Six kinds of checks, each on its own schedule. All of them are implemented inside the system, without third-party libraries — which is why it works on a network where nothing can be installed.
Plain monitoring answers one question: does the address respond. That is not enough on a real site — you must not raise a hundred alarms for one cause, nor wake the duty engineer over a single dropped packet.
A measuring device has not only a link but also a calibration deadline. Once it expires the device may work perfectly while its measurements are legally invalid. The system tracks this as a separate state.
A web panel with a section per equipment type. The map is built in and works without internet.
What the system deliberately does not do: mass writing of settings to production switches. Configuration is only read and kept in history, so monitoring cannot take the network down. Traffic flow analysis (NetFlow) is not there today: per-port traffic and errors are visible, but not the composition of the flows.
Monitoring keeps the infrastructure alive; the surveillance system provides live video and the archive; analytics turns the stream into events. Three parts of one delivery, each of which also works on its own.
