The cameras are the visible part of a system, but cable is what makes it reliable. A clean cable run means cameras that stay connected, wiring that is hard to cut and a home that does not look like a construction site. Houston-area homes add their own twists: hot attics, single-story houses on slab foundations and lots of brick. Here is how cable typically gets from the recorder to each camera.
Why Wired Cameras Need Planning
Most professional systems use PoE (Power over Ethernet). One network cable carries both data and power, so there is no need for an outlet at each camera. That makes the system more reliable but means every camera needs a continuous cable back to the recorder or a PoE switch. Planning those paths is the heart of the job. For the wired vs wireless decision itself, see our comparison.
Attic Runs: The Most Common Route
In many homes, cable runs from the recorder up into the attic, across the attic and down to each camera at the eaves or soffit. This keeps cable hidden and protected.
Practical points for attic work here: attics get extremely hot in summer, so installers often schedule attic work for cooler hours. Cable should be secured along framing rather than lying loose across insulation, and kept away from sharp edges and HVAC equipment. Low-pitch roofs near the eaves can make the last few feet the hardest part.
Single-Story Homes on Slab Foundations
Most homes in the region are built on concrete slabs, so there is no crawl space under the floor. Running cable under the house is not an option. Cable from a recorder in an interior closet usually goes up through the wall into the attic. If the closet wall is blocked by insulation, a fire block or a header, the installer may choose a different recorder location, such as a garage wall, to shorten and simplify runs.
Two-Story Homes
Second-floor cameras can be reached from the upper attic, but first-floor eaves under a second story may have no attic above them. Options include running cable inside the floor space between levels, through the garage ceiling, or along the exterior in a small paintable raceway.
Brick, Stone and Siding
Many homes here have brick exteriors. Drilling brick or mortar is routine with the right masonry bit; installers often drill through mortar joints because they are easier to patch. Every exterior hole should be sealed with an exterior-grade sealant so water and insects stay out. On siding, the camera is often mounted on a junction box that hides the connection and keeps it dry.
PoE Distance Limits
An Ethernet run is rated for about 100 meters (328 feet). That is plenty for most homes. Longer runs to a detached garage, gate or barn need a PoE switch partway, a PoE extender, or a fiber or wireless bridge between buildings. Our wireless IP camera service covers bridges for outbuildings.
Exterior Runs and Weatherproofing
When cable must run outside, it should be outdoor-rated, UV-resistant and secured in conduit or raceway where it is exposed. Connectors should sit inside a junction box or weatherproof cap, not hang in the open. Drip loops, a small downward curve before cable enters a hole, keep rain from running along the cable into the wall. For more on weather, see our guide to cameras in local weather.
Where to Put the Recorder
A good recorder spot has power, ventilation, a network connection to your router and is not obvious to an intruder. Interior closets, offices and climate-controlled utility rooms work well. Hot attics and unventilated cabinets shorten hard-drive life.
Choosing Cable
Use solid copper Cat5e or Cat6 rather than cheaper copper-clad aluminum, which can cause PoE problems over distance. Use outdoor or direct-burial cable for exposed or underground runs. Label both ends of each run so troubleshooting later is quick.
Frequently Asked Questions
How far can a PoE camera be from the recorder?
Standard Ethernet, including PoE, is rated for about 100 meters (328 feet) per cable run. For longer distances, a PoE switch or extender part-way along the run, or a fiber link between buildings, keeps the signal and power within spec.
Is Cat5e enough, or do I need Cat6?
Cat5e handles most IP cameras. Cat6 offers more headroom and is common in new installs. For exterior or buried runs, the jacket matters as much as the category: use outdoor-rated or direct-burial cable where it is exposed to sun and moisture.
Can cable be run without going into the attic?
Yes, though it is usually less tidy. Options include running along the exterior in paintable conduit or raceway, through a garage, or under eaves. In homes without accessible attic space, exterior routing is often the practical choice.
