Who we are hiring

Sales and technicians — real Pro shop work

DIY Pro Security is the factory-direct parts storefront for cameras, recorders, PoE networking, access control, intercom, and Ajax smart alarms. TEK (Technology Experience Knowledge LLC) handles local installs from 10770B Montgomery Rd, Cincinnati, OH 45242. We need people who show up, learn the gear, and talk to customers like humans — not a corporate careers portal.

Field

Technician

Hang cameras, pull cable, terminate connectors, set up NVRs/DVRs, and help with access, intercom, and Ajax jobs across Greater Cincinnati.

  • Comfortable on ladders, attics, and commercial sites
  • Know (or willing to learn) connectors, polarity, PoE, and basic networking
  • Valid driver’s license; local travel during the day
  • Prior CCTV, low-voltage, or electrical experience is a plus

Office

Sales

Help homeowners and Pros pick the right kit — quotes, product questions, Pro account follow-up, and handoffs to TEK install.

  • Clear written English; comfortable with email and phone-style chat
  • Learn the catalog: IP vs AHD, PoE, access, Ajax, tools & kits
  • Match customers to parts without overselling
  • Part-time or full-time depending on fit

What a tech should know

Plain-English security gear — our industry

You do not need a degree. You do need to know what plugs into what, why power matters, and how to explain it to a normal person. Here is the short version of what we sell and install every day.

IP CCTV vs AHD

IP cameras talk over network cable (usually Cat5e/Cat6 with RJ45). They land on an NVR (network video recorder) and often get power from PoE (power over Ethernet) — one cable for data and power. AHD is analog HD over coax (BNC connectors) into a DVR, with separate DC power on most cameras.

Connectors & wire

RJ45 goes on Cat5e/Cat6 for IP cameras, switches, and NVRs. BNC goes on coax for AHD video. DC barrel (or screw terminal) is camera/power supply DC. HDMI is monitor out. Do not mix them — wrong connector = no picture, no power, or a melted mood.

AC vs DC voltage

AC (alternating current) is wall power — it flips direction many times a second. DC (direct current) flows one way — that is what most cameras, NVRs, and Ajax hubs want from a power supply. Plug AC into a DC-only device and you toast gear. Always match voltage, polarity, and AC/DC on the label.

PoE, networking & polarity

PoE switches/injectors send DC power down the Ethernet pairs so IP cameras do not need a brick at the camera. Learn basic IP addressing, uplink vs camera ports, and cable length limits. On DC barrel and screw terminals, polarity matters — reverse it and nothing works (or something smells weird).

Access, intercom & Ajax

We sell Akuvox-style access/intercom (doors, readers, indoor stations) and Ajax wireless smart alarms (hub, detectors, sirens, app). Installers need clean cable routes, solid mounts, and patient customer walkthroughs — not jargon.

Ohm basics & TEK install

Resistance (ohms) rises with thin/long wire — voltage drop makes cameras brown out at the far end. Use the right gauge and keep power runs sane. TEK install is Greater Cincinnati first; travel jobs get quoted separately.

10 questions

Required. Connectors, AC vs DC, PoE, NVR/DVR, networking, access, Ajax, polarity — and one silly “is it a band?” check.

1. Which connector belongs on Cat5e / Cat6 for IP cameras?
2. AHD camera video usually rides on coax with which connector?
3. What is the main difference between AC and DC voltage?
4. “Is it a band?” — which answer is right in our shop?
5. PoE vs AHD — which is true?
6. NVR vs DVR — quick pick:
7. Basic networking: an IP camera needs a path to the recorder. What usually provides that path?
8. Access control / intercom in our catalog is mainly about:
9. Ajax smart alarms are best described as:
10. Polarity & ohms — which is solid tech sense?
