Can You Install a PoE Security Camera System Yourself?

Yes, most people who are comfortable on a ladder and with a drill can install a PoE security camera system themselves. The electronic side is close to plug and play: cameras plug into the recorder and appear on screen. The effort is almost all physical, in routing Ethernet cable from the recorder to each camera, drilling through walls or soffits, and keeping water out of the connections.

What a PoE NVR kit is

PoE stands for Power over Ethernet. One network cable carries both power to the camera and video back from it, so there is no separate power adapter and no outlet needed at the camera.

A typical kit contains:

• An NVR (network video recorder). A box with a row of PoE ports on the back, one per camera, and a hard drive inside for recordings. Many kits ship with the drive installed, but not all, so check.
• Several cameras, usually bullet or turret style, each with a short pigtail ending in an Ethernet socket.
• Ethernet cables, normally one per camera, in a fixed length that varies by kit.
• A mouse and a power supply for the NVR. A monitor or TV is usually not included.

The NVR sends low-voltage power down the cable following the IEEE 802.3af or 802.3at PoE standards. That is why this is a job a homeowner can take on: you are not wiring anything to the mains. Our PoE security camera systems guide covers the kits themselves, and the broader home security camera systems guide also includes coax DVR kits.

What is truly plug and play

• Camera into the NVR. Plug a camera into a PoE port and it powers up and shows on screen, usually within a minute or two. With a same-brand kit there is no pairing step and no Wi-Fi password to enter.
• NVR into a monitor or TV. An HDMI cable gives you the live view and menus. The setup wizard asks for a password, the date and time, and how you want to record.
• NVR into your router. One Ethernet cable to the router lets you watch from a phone app when you are away. This step is optional. The system records with no internet at all, which we explain in do security cameras work without Wi-Fi.

Do this first, on a table, before anything goes on a wall. Plug every camera into the NVR with the supplied cables and confirm each one shows a picture. Finding a dead camera or a bad cable now takes five minutes. Finding it after the cable is through the attic takes an afternoon.

What is real work

Planning the routes

Each camera needs its own cable back to the NVR. On a single-story house the usual route is up into the attic, across to the eaves, and out through the soffit. Other routes run through a basement or crawlspace, or along the outside of the house in conduit. Decide where the NVR will live, then measure each run and add slack for corners and drops.

Drilling

A pre-made cable has a plug on each end, so the hole has to be wide enough for the plug to pass, roughly three quarters of an inch. If you cut the cable and fit the plug yourself after pulling it through, the hole only has to fit the cable. Before drilling, check both sides of the wall for wiring and pipes. Angle an exterior hole so it slopes down toward the outside, which keeps rain from running in.

Running the cable

This is the slow part: crawling the attic, fishing cable down wall cavities and clipping it neatly. A fish tape or a set of fiberglass push rods makes it much easier. Keep bends gentle and do not staple through the cable.

Choosing and terminating cable

Cat5e and Cat6 both carry PoE camera video without trouble. What matters more is the conductor: buy solid copper cable, not copper-clad aluminum (CCA). CCA has higher resistance, so it wastes power as heat and delivers less to the camera on long runs. For runs exposed to sunlight use outdoor-rated cable, and for underground runs use direct-burial cable. Our Cat 6 Ethernet cable guide lists pre-made and bulk options.

If you buy bulk cable you will fit the RJ45 plugs yourself with a crimping tool. Use the same wiring order, normally T568B, on both ends, and check every cable with a tester. Expect your first few plugs to fail.

Weatherproofing

The connection between the camera pigtail and the cable is the weak point of every outdoor install. Moisture in that joint corrodes the contacts, and a corroded connector is a common reason a camera drops offline months later. Use the waterproof coupling supplied with the camera, and where possible tuck the joint inside the soffit, the wall or a junction box. Leave a drip loop, a low dip in the cable before it enters the wall, so water runs off the bottom of the loop. Seal the hole with exterior silicone.

The cable length limit

The Ethernet standard allows up to 100 meters (328 feet) per run, from the NVR port to the camera. Almost every house fits inside that. For a longer run, such as a camera on a far outbuilding, you need a PoE extender or a PoE switch part-way along. Some brands offer an extended-range mode that trades speed for distance, but it varies by model, so treat 100 meters as the limit unless the manual says otherwise.

The cables supplied in kits are much shorter than that limit. Measure your routes before you buy, because a camera at the far corner of the house often needs a longer cable than the one in the box.

Tools you will need

• A drill with a long bit or a spade bit sized for your holes
• A ladder that reaches the eaves safely
• Fish tape or push rods
• A stud finder
• Exterior silicone sealant and cable clips
• A screwdriver and wall anchors suited to your siding
• For bulk cable: a crimping tool, RJ45 plugs and a cable tester

When to hire someone

Consider paying an installer when:

• The house has two or more stories and no attic access above the camera positions.
• The exterior is brick, stone or stucco, which needs masonry bits and more care.
• A run has to go underground to a gate or outbuilding.
• You are not comfortable working at height.
• You want the cable hidden inside finished walls with no visible runs.

Look for a low-voltage or security camera installer. Many will fit a system you have bought yourself. Rules for low-voltage wiring vary by location, so check whether any permit applies where you live.

The wireless NVR alternative

If the cabling puts you off, a wireless security camera system uses the same idea, a recorder with a set of matched cameras, but the cameras send video to the recorder over Wi-Fi. There is no Ethernet to run. Be clear on what “wireless” means, though: in most of these kits each camera still needs a power cable to an outlet. Only battery and solar models are fully wire-free.

The trade-off is reliability. A cable is not affected by walls, distance or interference, and a wireless link is. For one or two cameras, single Wi-Fi models from our outdoor security cameras guide are simpler still.
