Fault checks: CCTV cameras consuming excessive network bandwidth
Stop CCTV traffic from overwhelming the wider network. This page covers the causes worth checking on wireless CCTV systems, what you can safely check yourself, and what an engineer does on the visit.
- Fault: cCTV cameras consuming excessive network bandwidth
- System in view: wireless CCTV system
- Priority: safe to handle as planned work
Symptom
General internet use slows noticeably when cameras are active
Check first
Note whether the slowdown correlates with motion-heavy periods or is constant throughout the day
Likely cause
Cameras set to unnecessarily high bitrate
Typical presentation
The underlying question is simple, stop CCTV traffic from overwhelming the wider network.
- General internet use slows noticeably when cameras are active
- Network monitoring shows cameras as the dominant traffic source
The relevant hardware on wireless CCTV systems
The reason this matters: a wireless CCTV system fails in a different order to other kit.
- NVR or cloud recording target
- Receives and stores the video the cameras transmit.
- Power supply at each camera position
- Cameras still need power, even without a data cable.

- Recording and offline camera fault diagnosis

Where the fault normally originates
- Cameras set to unnecessarily high bitrate
- Continuous recording at maximum resolution and frame rate generates far more data than most scenes actually require for identification purposes.
- Cameras sharing the same network as general office or household traffic
- Without separation, camera traffic and everyday internet use compete directly for the same available bandwidth.
Why it matters more on a home with frequent deliveries
- Any unlocked outbuilding used as a safe place
- That is the access route that needs to be covered reliably, which is why cCTV cameras consuming excessive network bandwidth there is worth fixing rather than living with.
- A parcel box or lockable store
- Removes the problem rather than recording it happening.
What the visit involves
Timing-wise: safe to handle as planned work.
- 1Switch cloud-connected cameras to event-based upload where continuous upload is not actually required
- 2Enable variable bitrate encoding where supported to reduce output during quiet periods
Before you pay anybody
Nothing below needs a screwdriver, a ladder or the cover off anything.
- 1Note whether the slowdown correlates with motion-heavy periods or is constant throughout the day
- 2Check each camera's current resolution, frame rate and bitrate setting against what the application actually needs
A limit worth knowing before you spend anything
Cameras still need a power source at each position unless battery-powered, so it is not entirely cable-free. Wi-Fi signal strength and camera connectivity checked at each service visit, particularly after any changes to the router or network layout.
On the ground in Tunstall
Across the ME9 postcodes, quiet residential streets that border open countryside south of Sittingbourne, perimeter detection on the field-side elevations is the most-asked-for upgrade.
Preventing a repeat
Size camera settings and network segmentation together at install rather than accepting factory defaults, which are usually set for maximum quality rather than sensible bandwidth use.
