FNIRSI LPM-10A for CCTV Installers Malaysia – 7 Useful Network Testing Jobs
FNIRSI LPM-10A for CCTV Installers Malaysia – 7 Useful Network Testing Jobs
Modern CCTV installation is no longer only about connecting cameras to a DVR.
With IP cameras, PoE switches, NVR systems and Ethernet cabling, CCTV technicians increasingly need basic network troubleshooting capability.
The FNIRSI LPM-10A Network Cable Tester combines several useful network testing functions into one handheld instrument.
For CCTV installers in Malaysia, it can be useful during installation, commissioning and troubleshooting.
Here are seven practical jobs where the FNIRSI LPM-10A can help.
1. Check a Newly Terminated RJ45 Cable
One of the most common CCTV installation jobs is terminating Ethernet cables.
After installing the RJ45 connector, do not assume the cable is correct just because the wires appear properly arranged.
Test it.
The LPM-10A can help check the cable connection and identify abnormal wiring conditions.
This is especially useful when installing multiple IP cameras in one project.
Imagine terminating 30 camera cables.
Finding a bad termination before commissioning is much easier than troubleshooting it after all cameras have been installed.
2. Find Which Cable Belongs to an IP Camera
A CCTV cabinet may contain many similar Ethernet cables.
The labels may say:
CAM 01
CAM 02
CAM 03
But what happens when the labels are missing?
Or somebody changed the connections during previous maintenance?
The cable tracing function of the FNIRSI LPM-10A can help technicians identify the corresponding cable.
This becomes especially useful in existing CCTV systems where the original installer is no longer available.
Instead of guessing which cable belongs to a camera, trace it.
3. Check PoE for an Offline Camera
An IP camera suddenly goes offline.
A common reaction is:
“Camera rosak?”
Maybe.
But the camera is only one possible cause.
The problem could also involve:
PoE switch
Network cable
RJ45 connector
Switch port
Power supply
Network configuration
The LPM-10A includes PoE detection capability, allowing technicians to check whether PoE is present as part of the troubleshooting process.
This can help avoid replacing a camera before checking its network and power connection.
4. Measure the Network Cable Length
IP cameras are often installed far away from the network cabinet.
For example:
Car park
Guard house
Warehouse
Factory entrance
Loading bay
Building perimeter
Upper floor
The cable may travel through ceilings, conduits and cable trays, making its actual length difficult to estimate visually.
The cable length measurement function of the FNIRSI LPM-10A can provide useful information about the installed cable run.
This can support both installation checking and troubleshooting.
5. Find the Correct PoE Switch Port
Suppose you know which camera has a problem.
You know the cable.
But which port on the PoE switch is connected to it?
This becomes difficult when dealing with:
24-port switches
48-port switches
Multiple PoE switches
Poorly labelled installations
The port flashing function can assist technicians in identifying the associated switch port.
This reduces the need to unplug cables randomly.
That is particularly important when the CCTV system is still operating and other cameras should remain online.
6. Troubleshoot an Intermittent Camera Connection
Some CCTV problems are not complete failures.
The customer may report:
“Camera sometimes online, sometimes offline.”
Or:
“At night this camera always has a problem.”
Intermittent problems require more systematic troubleshooting.
Check:
RJ45 termination
Cable condition
PoE source
Switch port
Installed cable run
Camera connection
Network equipment
If the camera works normally using a short known-good cable beside the switch but becomes unstable at its installed location, the permanent cabling deserves closer investigation.
The LPM-10A gives technicians several functions for investigating that physical network path.
7. Troubleshoot an Existing CCTV Installation
This may be one of the strongest applications.
Installing a completely new system is relatively straightforward because you know:
Where every cable goes
Which switch port is being used
How the cables were installed
Which equipment was installed
Servicing somebody else's five-year-old CCTV installation is different.
You may find:
No drawings
Missing labels
Changed switch ports
Unused cables
Unknown cable routes
Different brands of equipment
Old and new cameras mixed together
In this situation, a multifunction network tester becomes much more valuable.
You can work through the system step by step.
Trace the cable.
Check the wiring.
Check the approximate cable length.
Check PoE.
Identify the switch port.
Then continue with network or camera troubleshooting.
Example: One Camera Is Offline
Suppose a factory has 32 IP cameras.
Only Camera 17 is offline.
The other 31 cameras are operating normally.
A practical troubleshooting sequence would be:
Step 1 – Inspect Camera 17 and its RJ45 connection
Check for physical damage, loose connection or moisture.
Step 2 – Check the cable
Investigate the Ethernet connection and termination.
Step 3 – Check PoE
Determine whether the expected PoE supply is present.
Step 4 – Trace the cable
Identify the corresponding cable inside the CCTV cabinet.
Step 5 – Identify the switch port
Locate the port associated with Camera 17.
Step 6 – Compare with a known-good connection
Where appropriate, use known-good equipment or connections to isolate the problem.
This is much more systematic than immediately ordering a new camera.
What If Eight Cameras Are Offline?
Now imagine Cameras 1–8 all go offline simultaneously.
The troubleshooting strategy should change.
Eight individual cables failing at exactly the same time is less likely than a shared problem.
Check common equipment such as:
PoE switch
Switch power supply
Network uplink
NVR/network connection
Shared electrical supply
The pattern of the failure matters.
One camera offline → investigate the individual connection.
Many cameras offline together → investigate shared infrastructure first.
A good technician does not only know how to use a tester.
A good technician knows where to test first.
FNIRSI LPM-10A vs Basic RJ45 Tester for CCTV
A basic RJ45 tester can still be useful.
If your main requirement is:
“Did I terminate this cable correctly?”
a simple tester may be enough.
But professional CCTV service work often involves additional questions:
Which cable belongs to this camera?
How long is the installed cable?
Is PoE present?
Which switch port is connected?
Where should I continue troubleshooting?
This is where a multifunction tester such as the FNIRSI LPM-10A becomes more useful.
Is the FNIRSI LPM-10A a CCTV Tester?
It is better described as a network cable testing and troubleshooting tool rather than a complete CCTV tester.
This distinction is important.
A dedicated CCTV tester may provide functions specifically designed for camera commissioning, depending on the model.
The LPM-10A instead focuses on the network cabling side of the installation.
For IP CCTV technicians, that can still be extremely useful because the Ethernet cable and PoE connection are critical parts of the system.
Who Is the FNIRSI LPM-10A Suitable For?
The LPM-10A can be considered by:
CCTV installers
Security system contractors
Network technicians
IT support teams
Building maintenance personnel
Structured cabling contractors
Factory maintenance teams
Field service technicians
It is particularly useful for technicians who regularly troubleshoot existing IP CCTV and network installations.
One Tester, Multiple Troubleshooting Steps
The main advantage of the FNIRSI LPM-10A for CCTV installers is not one individual feature.
It is the ability to perform several commonly required checks with one instrument:
Cable tracing
Wire-map checking
Cable length measurement
PoE detection
Switch-port identification
Network-related testing
For field service work, carrying fewer instruments while still covering common network problems can make troubleshooting more efficient.
