Serving Markham

Markham homeowners increasingly ask us for smart lighting and EV charger installations alongside standard repairs, while local businesses rely on us for ongoing commercial electrical maintenance. Our licensed electricians serve Markham with the same upfront pricing and code-compliant work as everywhere else in the GTA.

In Unionville and Berczy Village, where many homes were built from the 1990s onward, we see more EV charger installations, smart dimmer upgrades, and potlight retrofits than panel replacements. Cornell’s newer new-urbanist homes bring similar requests alongside the occasional builder-grade panel that needs upsizing for a renovation. Around Milliken and Markham’s tech and office corridors, commercial electrical maintenance and lighting retrofits are our most common calls.

Security Camera Installation in Markham: What to Expect

Unionville and Berczy Village homes from the 1990s onward often have some existing wiring infrastructure we can build on, so camera additions there are frequently upgrades or expansions to an existing system rather than a ground-up install. Cornell’s new-urbanist layout, with narrower lots and shared walkways, means camera placement has to account for a neighbour’s entrance being closer than usual — the same consideration as doorbell placement there, but it matters more with a wider-angle camera. Around Milliken and Markham’s tech and office corridor, most requests are for commercial systems covering office entrances, parking structures, and sometimes server rooms or equipment areas that need their own dedicated coverage.

Security Camera Installation in Markham

Overview

We provide security camera installation for homes and businesses throughout Markham, including Unionville, Milliken, Cornell, Berczy Village, and the rest of Markham.

A security camera system is only as reliable as the wiring and power behind it. We install and wire security camera systems for homes and businesses, including PoE (Power over Ethernet) IP cameras, traditional CCTV/DVR setups, and NVR recorder installations, running new low-voltage cable where none exists, installing dedicated circuits and PoE switches for camera power, and mounting cameras for solid coverage of entrances, driveways, and blind spots. Electrovoltage works with homeowners, retail and commercial property owners, and general contractors on new camera systems, expansions to existing setups, and rewiring jobs where cameras were originally installed with underrated or exposed cabling.

  • PoE & traditional CCTV/DVR wiring
  • Dedicated circuits for PoE switches & recorders
  • Camera mounting & coverage planning included

Why It Matters

Most security camera problems trace back to power and wiring, not the camera itself: a PoE switch that can’t supply enough wattage for the number of cameras connected, cable runs that weren’t rated for outdoor exposure and degrade within a season, or a DVR/NVR powered from a shared outlet that browns out when the system draws a startup surge. Camera placement also depends on where power and data can actually reach, so planning the electrical and low-voltage wiring alongside camera positions, rather than mounting cameras first and figuring out power after, is what determines whether the finished system actually covers what it’s meant to.

How Security Camera Installation Works

  1. 1

    Site walkthrough & coverage planning

    We review your property, identify entrances, driveways, and blind spots to cover, and plan camera positions against realistic cable and power routing.

  2. 2

    Power & PoE planning

    We size PoE switches and injectors or dedicated circuits for your camera count, and check panel capacity for the recorder and network equipment.

  3. 3

    Wiring installation

    We run new low-voltage or PoE cabling rated for indoor or outdoor use, or work with existing cabling where it’s in good condition.

  4. 4

    Mounting, testing & handover

    We mount cameras, connect and test every camera feed against the recorder or app, and confirm stable power before we leave.

What Affects the Cost

Unionville and Berczy Village jobs are often priced as system expansions rather than new installs, Cornell jobs sometimes need extra planning time for angle adjustments on narrower lots, and Milliken-area commercial jobs scale with the number of zones — entrances, parking, equipment areas — needing coverage.

Cost depends on the number of cameras and whether cabling is PoE or traditional CCTV, how much new low-voltage wiring needs to be run and how accessible that route is, whether a dedicated circuit is needed for the PoE switch or recorder, and whether the job includes an NVR/DVR setup or integrates with an existing recorder.

Frequently Asked Questions

I already have two cameras on my Unionville home — can you add more to the same system?
Usually, yes. Homes in that era in Unionville and Berczy Village often have a PoE switch or NVR with spare capacity, so adding cameras is often an expansion rather than starting over.
My townhouse in Cornell is close to my neighbour’s — how do you keep the camera from recording their door?
We plan the mounting angle specifically around that. Cornell’s narrower lots and shared walkways mean we’re more deliberate about field of view than on a typical detached lot.
Do you install PoE security cameras or only traditional CCTV?
We install both. For PoE (Power over Ethernet) IP camera systems we size and wire the PoE switch or injectors correctly, and for traditional CCTV/DVR setups we run the coax and power cabling needed for each camera.
Can you add cameras to a system that already exists?
Yes, we regularly extend existing camera systems, adding cameras to spare NVR or DVR channels, or upgrading the PoE switch if the existing one doesn’t have capacity for more cameras.
Do you run new wiring if my property has none?
Yes, we run new low-voltage or PoE cabling rated for indoor or outdoor use to wherever cameras need to go, including routing through finished walls, attics, or exterior siding.
Why do my cameras keep dropping offline or losing power?
This is usually a power issue: a PoE switch undersized for the number of cameras connected, or a DVR/NVR sharing a circuit that can’t supply a stable load. We size the power supply correctly for your camera count.
Do you install the NVR or DVR recorder as well as the cameras?
Yes, we install and wire the recorder, connect and test every camera feed, and confirm the system is accessible on your network or app before we finish.
How much does security camera installation cost?
Cost depends on your camera count, whether the system is PoE or traditional CCTV, how much new wiring needs to be run, and whether a dedicated circuit is needed. We provide a clear quote after reviewing your property.
