Camera, Speaker, and Coax Wiring in Indianapolis

Cameras, speakers, and TVs all share one weak point: the cable that feeds them. A camera on a loose connection loses its picture. A speaker on undersized wire sounds thin. A coax line split too many times delivers a fuzzy channel or a modem that keeps resetting. MaryComm Wiring handles camera, speaker, and coax wiring in Indianapolis, running the right cable to each device so the equipment can do its job.

Security Camera Wiring

Camera wiring starts with knowing the camera type:

  • •**IP cameras** connect over network cable and usually draw power through it as well, so one run handles both video and power.
  • •**Analog and HD-over-coax systems** use coaxial cable, often paired with a separate power line.

Matching the cable to the camera before anything is pulled avoids running the wrong line to every location.


Outdoor locations need extra care. Cable on the exterior should be rated for outdoor exposure and should enter the building through a sealed opening. A drip loop lets water run off at the low point instead of following the cable inside.

Security cameras, speakers, and coaxial lines each need a clean cable path to work the way they should. Camera, speaker, and coax wiring runs and connects the cable to each device, whether that is one camera over a door or a set of speakers across several rooms.

Cameras, Speakers, and Coax

Speaker Wiring

Speakers in a ceiling, on a patio, or across a dining area all need wire sized to the distance and rated for where it runs. Longer runs call for heavier wire, because thin wire over a long distance loses power before it reaches the speaker. Cable inside walls needs an in-wall rating.


Planning matters as much as the wire itself. Each speaker or zone is run back to the location of the amplifier or receiver. When the equipment supports it, rooms wired as separate zones can then be controlled independently.

Coax Wiring

Coaxial cable still carries cable TV, satellite signals, and many internet connections. Problems usually come from age and from splits. Every splitter divides the signal, and old fittings let interference in.


Coax work covers:

  • new runs to additional TV or modem locations
  • replacing worn connectors
  • cutting back unnecessary splits so the signal arriving at each outlet stays strong

Related Services

Cameras that run on the network depend on the equipment behind them, which is where network installation comes in: the switch that powers the cameras, the recorder, and the internet connection that lets you view footage remotely. For data and phone runs elsewhere in the building, see wiring installation and repair. Every service MaryComm Wiring offers appears on the MaryComm Wiring home page.

Frequently Asked Questions

  • What cable do security cameras use?

    IP cameras use Cat5e or Cat6 network cable, typically with Power over Ethernet so one cable carries both power and video. Analog and HD-over-coax cameras use RG59 coaxial cable, often in a siamese version that bundles a power pair alongside it. The camera system decides which cable gets run.

  • What gauge of speaker wire is needed?

    For most room-length runs, 16-gauge wire is common. Longer runs, or speakers with lower impedance, call for 14-gauge or heavier. Wire run inside walls should carry a CL2 or CL3 rating for in-wall use.

  • What is the difference between RG6 and RG59 coax?

    RG6 has a thicker center conductor and better shielding. It is the standard for cable TV, satellite, and cable internet modems. RG59 is thinner and is mainly used for analog security camera runs over shorter distances.

  • Why does the TV signal weaken after adding more outlets?

    Every split divides the signal, and a standard two-way splitter cuts roughly 3.5 dB from each output. Several splits in a row, along with old fittings, can push a weak signal below what a TV or modem needs. Reducing splits, replacing connectors, or adding a dedicated run usually restores it.

  • Can camera cable run along the outside of a building?

    Yes, provided the cable is rated for outdoor and UV exposure. Exterior runs are secured along the building, protected or placed in conduit where they could be damaged, and brought inside through a sealed entry with a drip loop.
