Security camera installation in Dearborn and Metro Detroit
HD and 4K camera systems for homes, storefronts, offices and warehouses, set up so you can check every camera from your phone.

A camera system is only useful if it covers the right spots, records clearly at night and is easy to check when something happens. Temark walks your property first, marks every entry, register, lot and blind corner, then designs a system around what you actually need to see.
We run the cable, mount and aim each camera, set up the recorder, and put the app on your phone before we leave. If you already have an older analog system, we can often reuse the existing wiring and upgrade the cameras and recorder.

How many cameras does a building really need?
Tap the mounting points to add or remove cameras and watch the coverage change. It is the same thinking we do on a walkthrough, minus the ladder.

Questions about security cameras
Straight answers about how we work. Call if yours is not here.
How many cameras do I need?
Most homes are well covered with 4 to 6 cameras: each door, the driveway and the backyard. Small businesses usually need 6 to 16 depending on entrances, registers, stock rooms and parking. We count with you on the walkthrough.
Can I watch the cameras from my phone?
Yes. Every system we install includes remote viewing on your phone and computer, and we set it up and show you how to use it before we leave.
Can you reuse my old camera wiring?
Often, yes. Many analog systems can be upgraded with new cameras and a new recorder over the existing coax, which saves on labor. We will tell you on the walkthrough whether that makes sense.
How long are recordings kept?
It depends on the number of cameras, resolution and hard drive size. Most of our systems keep 2 to 4 weeks of continuous recording, and we can size storage for longer if you need it.
