Where security installers buy
Security installers buy cameras, panels and cable from a security distributor that sells to the trade, and fill gaps from electrical and data suppliers.

Your counter list
The items security installers buy every week, from the van stock on our tools list. Ask each supplier for a price on these first; they decide which account saves you the most.
| Item | Why it is on the list |
|---|---|
| Cat6 cable and coax in boxes | Most jobs need a few runs |
| Connectors, jacks and keystones | Terminations and repairs |
| Low voltage brackets and wall plates | Every new device |
| Cable staples, ties and Velcro straps | Neat runs the customer can see |
| Junction boxes for cameras | Weatherproof mounts outside |
| Spare power supplies and fuses | Common service calls |
For the first order, price the starter kit too: fish tape, glow rods and a drill with long flex bits; cable stripper, crimper and punchdown tool; network cable tester; nonconductive voltage tester; digital multimeter; multi-position ladder; cordless drill and impact driver; low voltage brackets and a hole saw kit; laptop or tablet with the setup apps. Bigger purchases to price at a dealer or rental house: cable certifier or advanced tester; tone and probe kit; poe tester; extension ladder and a lift rental account; label maker.
Opening a trade account
Bring your business name, tax ID and license number, and a credit application if you want terms. The big-box programs are compared row by row on Home Depot Pro vs Lowe's Pro. For the tools themselves, the security and low voltage tools list has prices read on the makers' own sites (Fluke, Little Giant).
When supplier prices change
Update your security and low voltage price list the same week a supplier raises prices. In Koira, that price list is what your estimates are built from.
