One Cable. Two Jobs. That's How a PoE Camera Works.

You've probably spotted "PoE NVR System" on a Shopee listing and thought, "sounds complicated." Sounds like something you'd need an IT person for.

Here's the short answer: a PoE camera receives both electrical power and video data over a single Ethernet cable. One cable. That's it.

No separate power adapter is included with the camera. No complex wiring. For most Malaysian terrace houses and shophouses, the whole system can be set up in half a day without calling anyone.

This article covers:

• What PoE actually means and why it only needs one cable
• How the system works from camera to phone, step by step
• Exactly what you need to buy to get it running
• How PoE compares to WiFi cameras, honestly

What Is a PoE Camera and Why Does It Only Need One Cable?

A PoE camera is an IP security camera that receives power and transmits video over the same Ethernet cable.

PoE stands for Power over Ethernet. The same flat cable that connects your router to a TV box or printer can carry both a data signal and a small amount of electrical current simultaneously.

This solves a real problem with traditional CCTV cameras.

With older systems, every camera needed two separate connections at the mounting location: a power cable to a nearby wall socket, and a data cable to the recorder. If there was no socket near your porch or gate, you needed an electrician to add one.

PoE eliminates that entirely.

One cable runs from the NVR (the recorder unit) to each camera location. The NVR supplies power through that cable. The camera powers on, starts recording, and sends footage back through the same cable.

The wall socket stays at the NVR, not at each camera. This means you can mount cameras exactly where you need coverage: under eaves, at a gate, on a high corner of your shophouse exterior.

SriHome Malaysia PoE cameras support cable runs of up to 100 metres per camera, which is more than enough for virtually any Malaysian home or small business.

How a PoE Camera Works: Step by Step

Here is the full sequence from camera to your phone screen:

Step 1: Camera captures and encodes video. The camera lens captures live footage and converts it into a digital video stream.

Step 2: Ethernet cable carries power and data simultaneously. The cable running from the NVR to the camera does two things at once: it delivers low-voltage power to run the camera, and it carries the live video data back to the NVR. Think of it as a pipe with two lanes going in opposite directions.

Step 3: NVR supplies power to the camera through its built-in PoE ports. The NVR detects each camera plugged into its PoE ports and automatically supplies the correct power level. No manual configuration needed.

Step 4: NVR records footage to the hard drive locally. All video is stored on a hard drive installed inside the NVR. No internet connection is required for recording. Even if your broadband goes down, the cameras keep recording.

Step 5: View live or recorded footage on your phone or a monitor. Connect the NVR to your home router via Ethernet for remote phone access through the SriHome app. Or plug in any HDMI monitor or TV for on-site viewing without using your phone.

That's the complete chain: camera captures, cable carries, NVR records, you watch.

What Do You Need to Set Up a PoE System?

Five components. Here's exactly what each one does and what's included in a SriHome kit:

The hard drive is the item almost every first-time buyer forgets to budget for.

The NVR will not record without one installed. A 2TB desktop HDD gives you roughly 14–28 days of continuous footage across 4 cameras at 1080p before it starts overwriting the oldest recordings. A 4TB drive extends that to approximately 28–56 days.

Standard desktop HDDs are widely available in Malaysia at any electronics shop.

PoE Camera vs WiFi Camera: What's the Actual Difference?

The biggest difference is how the camera receives power, not how it sends video.

A WiFi camera is not fully wireless. It still needs a power adapter plugged into a wall socket near the camera location. It sends video wirelessly, but it needs a socket. If there's no socket at your preferred camera spot, you're still calling an electrician.

A PoE camera, by contrast, receives power through the Ethernet cable from the NVR. No socket at the camera. No adapter. Just the cable.

Here's the full comparison:

 

A note on reliability that international articles rarely mention: Malaysian buildings are predominantly concrete construction, including terrace houses and shophouses. WiFi signals attenuate more noticeably through concrete than through the timber-frame walls common in Western countries. This makes the reliability gap between PoE and WiFi more meaningful in a Malaysian context than overseas comparison guides suggest.

For permanent multi-camera installations in a landed home or shop, running cables once and forgetting them is less ongoing work than managing WiFi dropouts, app re-pairs, and range limitations.

That said, if cabling is genuinely not possible (you're renting, the ceiling is sealed, there's no practical route), a WiFi NVR is the smarter choice. Neither system has a subscription fee or cloud storage costs with SriHome.

Do You Need a Contractor to Set Up PoE Cameras?

No. And this is where most people are surprised.

PoE cameras receive low-voltage data power through the Ethernet cable. There is no electrical wiring involved. You are routing a data cable, not connecting to your building's electrical circuits. An electrician is not needed and not relevant to this task.

The installation job is running Cat5e or Cat6 cable from the NVR location to each camera mounting point.

What does that actually look like in a Malaysian terrace house?

The NVR sits at the ground floor, near your broadband router (it needs one Ethernet connection to the router for remote phone access). From there, you route a separate cable to each camera location.

Typical distances for a 2-storey terrace house:

• Front porch camera: 15–25 metres
• Rear garden or kitchen door: 20–30 metres
• Side gate: 25–35 metres

Every one of those runs is well within the 100-metre cable limit.

Cable is routed through existing ceiling cavities (common in Malaysian terrace houses), along skirting boards, or through a conduit pipe along the exterior wall. No drilling through structural walls required. No new power points needed.

A 4-camera setup typically takes 3–5 hours for a homeowner doing it for the first time.

One practical tip: seal the cable entry point into each outdoor camera with weatherproof silicone sealant after installation. Malaysia's humidity and tropical rain will eventually find an unsealed gap.

Once you know your cameras are going in, placement matters as much as the hardware. See our guide on where to install security cameras for room-by-room and outdoor placement recommendations for Malaysian homes and shops.

Is a PoE System Right for You?

Choose PoE NVR if:

• You own your property (or have the landlord's permission to route cables)
• You're installing 3 or more cameras permanently
• Cameras need to go at gates, outdoor corners, or locations without nearby power sockets
• You have a shophouse, factory, or SME premises that needs reliable 24/7 recording
• Long-term reliability matters more than the one-time effort of running cables

Choose WiFi NVR if:

• You're renting and cannot drill or route cables
• Your property has sealed concrete ceilings with no cable access
• You're setting up 1–2 cameras in accessible indoor locations
• Flexibility to move cameras around is more important than permanent coverage

One Cable Really Does Do It All

A PoE camera system is more straightforward than the name suggests.

One Ethernet cable per camera carries power from the NVR and transmits footage back to the NVR. No electrician. No cloud subscription. No subscription fees of any kind.

For most Malaysian terrace houses, cable runs stay well under 40 metres. A 4-camera setup is a realistic half-day project for a homeowner doing it for the first time.

If you want permanent, wired, reliable CCTV for your home or shop, a PoE NVR system is the right choice. If cabling isn't practical for your property, a WiFi NVR offers the same recording capability without the cabling.

Both options are available with zero hidden fees at SriHome.
