Fault checks: poE port on the recorder or switch not powering a camera
Fix a camera that stopped getting power over the network cable. This page covers the causes worth checking on surge protection device systems, what you can safely check yourself, and what an engineer does on the visit.
- Fault: poE port on the recorder or switch not powering a camera
- System in view: surge protection device system
- Priority: worth dealing with quickly rather than leaving over a weekend
Symptom
Camera has no power LED and does not appear on the network
Check first
Note whether the fault appeared after adding new equipment to the same switch
Likely cause
Individual PoE port failure
The behaviour people describe
Put plainly, the goal is that fix a camera that stopped getting power over the network cable.
- Camera has no power LED and does not appear on the network
- Camera works when plugged into a different port
The relevant hardware on surge protection device systems
A surge protection device system behaves differently from the rest, so the check order changes.
- Surge-protected socket strips
- Give individual device-level protection for equipment plugged directly into them.
- Earthing and bonding
- Ensures surge energy has a proper path away from equipment, which the protection devices depend on to work effectively.

The causes we check first
- Individual PoE port failure
- PoE ports carry higher current than standard data ports and fail one at a time far more often than the rest of the unit.
- Cable run exceeding supported length or quality
- Long or poor-quality cable runs cause voltage drop that starves the camera of usable power even though data still passes.
Why it matters more on a smallholding
- Separate outbuildings, stores and animal housing distributed across the holding
- That is the access route that needs to be covered reliably, which is why poE port on the recorder or switch not powering a camera there is worth fixing rather than living with.
- Camera coverage of field gates and vehicle access points
- These are the routes most likely to be used for removing equipment or livestock, and they see little natural observation compared with the house.
How we put it right
In terms of priority, it is worth dealing with quickly rather than leaving over a weekend.
- 1Re-terminate the cable run if length or connection quality is marginal
- 2Check total load on the switch's power budget across all ports
Try these first
Nothing below needs a screwdriver, a ladder or the cover off anything.
- 1Note whether the fault appeared after adding new equipment to the same switch
- 2Try the camera's lead in a different PoE port to see if the fault follows the port
A limit worth knowing before you spend anything
Protection devices themselves have a working life and typically need periodic replacement or testing after a significant surge event. Periodic testing of surge devices, particularly after any known significant surge event, and inspection of earthing where protection performance is in doubt.
On the ground in Peckham
Across the SE15 postcodes, side-return-extension density on terraces creates new ground-floor vulnerabilities, kitchen-extension PIR cover is part of every quote.
Preventing a repeat
Leave headroom in the PoE power budget when adding cameras, rather than loading a switch to its rated maximum from day one.
