Why Small Businesses Overpay for Security
Walk into an ADT or Vivint sales call as a business owner and you will hear “commercial-grade” pricing: $2,000+ equipment, $50-$100/month monitoring, 3-5 year contracts. For a 10-person office, a retail shop, or a small warehouse, that is overkill.
DIY home security systems work for most small businesses. They use the same sensors, cameras, and monitoring stations. The difference is you install them yourself and pay a fraction of the cost. Here are the 5 best options.
Quick Comparison
| System | Equipment | Monthly | Contract | Cameras | Best For |
|---|---|---|---|---|---|
| Abode | $150–$399 | $0–$20 | None | Yes (Cam 2) | Offices, retail with smart home needs |
| SimpliSafe | $199–$509 | $0–$28 | None | Yes (4 models) | Retail stores wanting video verification |
| Ring Alarm | $200–$330 | $10–$20 | None | Yes (extensive) | Businesses in Amazon ecosystem |
| Cove | $149–$399 | $15–$28 | None | No | Simple sensor-only alarm needs |
| Reolink + NVR | $300–$800 | $0 | None | Yes (only) | Warehouses needing cameras only |
1. Abode — Best Overall for Small Business
Why: Abode is the only system here with a genuinely free tier that includes app control, automation rules, and smart home integration. For a small business that wants sensors on doors and windows, a motion detector, and maybe a camera — without paying monthly — Abode is the clear pick.
Setup for a small office:
- Smart Security Kit ($150 on sale) — gateway, door sensor, motion sensor, key fob
- 3x extra Mini Door Sensors ($60) — cover additional entry points
- Abode Cam 2 ($25) — interior camera
- Keypad 2 ($70) — for employees to arm/disarm with individual codes
Total equipment: ~$305. Monthly: $0 (free tier) or $6 for Standard monitoring with professional dispatch.
The Keypad 2 supports unique codes per user, so you know which employee armed or disarmed. CUE automations let you auto-arm every night at closing time and auto-disarm before opening. HomeKit, Alexa, and Google support means you can integrate lights and locks.
3-year cost (with Standard monitoring): $305 + $216 = $521
2. SimpliSafe — Best for Retail Stores
Why: SimpliSafe’s video verification (Live Guard) is a standout for retail. When the alarm triggers, SimpliSafe agents can view camera feeds in real-time and confirm the break-in to police. This gets faster dispatch — verified alarms jump the queue.
Setup for a retail store:
- The Haven kit ($489) — base station, keypad, 4 entry sensors, 2 motion sensors, panic button
- SimpliCam ($99) — interior camera
- Outdoor Camera ($170) — covers the entrance
Total equipment: ~$758. Monthly: $28 (Interactive plan with video verification at $10 add-on).
The downside: SimpliSafe’s free tier has no monitoring at all — just local siren. For a business, you probably want professional monitoring. That $28/month adds up.
3-year cost (Interactive + Live Guard): $758 + $1,368 = $2,126
3. Ring Alarm — Best Camera Ecosystem
Why: If you need 4+ cameras covering a parking lot, entrance, stockroom, and office, Ring’s camera lineup is the deepest. Floodlight cams, stick-up cams, spotlight cams, doorbells — all in one app with one subscription.
Ring Protect Plus ($20/month) covers unlimited cameras at one location. That is a better deal than per-camera pricing once you pass 2 cameras.
The trade-off: Ring requires the $10–$20/month plan to unlock most features. Without it, cameras save nothing to the cloud, and the alarm has no monitoring. Ring also does not support HomeKit.
3-year cost (5-piece kit + 3 cameras + Protect Plus): ~$730 + $720 = $1,450
4. Cove — Cheapest Monitored Alarm
Why: If you only need door/window sensors and professional monitoring — no cameras — Cove is the cheapest monitored option. Equipment starts at $149, monitoring at $15/month.
Cove’s InstaText crash-and-smash protection dispatches even if someone destroys the panel. Cellular backup is included on all plans. The equipment is basic but functional.
The gap: zero cameras. For a business, this means no visual verification, no footage for insurance claims. You will need a separate camera system. See our best no-subscription cameras to pair with Cove.
3-year cost (basic kit + Basic plan): $199 + $540 = $739
5. Reolink NVR System — Best Camera-Only Setup
Why: Warehouses, workshops, and storage facilities often need cameras more than alarm sensors. A Reolink 4-camera PoE NVR kit ($350–$600) gives you 4K recording with zero monthly fees. All footage stored on the included hard drive.
No alarm system, no monitoring, no smart home. Just cameras that record 24/7. RTSP support means you can integrate with NAS or Blue Iris for advanced setups.
For businesses that also need intrusion detection, pair with a no-contract alarm system — Abode + Reolink is a strong combo under $500 total.
3-year cost (4-camera kit): ~$450 + $0 = $450
Commercial Systems vs DIY: The Real Cost Gap
| Approach | Equipment | 3-Year Monitoring | Total |
|---|---|---|---|
| ADT Commercial | $1,500–$3,000 | $2,160–$3,600 | $3,660–$6,600 |
| Vivint Business | $1,000–$2,500 | $1,800–$2,700 | $2,800–$5,200 |
| Abode DIY (Standard) | $305 | $216 | $521 |
| SimpliSafe DIY (Interactive) | $758 | $1,008 | $1,766 |
| Reolink cameras only | $450 | $0 | $450 |
The savings range from $1,000 to $6,000 over 3 years. For a small business, that is real money.
What About Insurance?
Most commercial property insurers offer 5–15% discounts for monitored alarm systems. DIY systems with professional monitoring (Abode Standard, SimpliSafe Interactive, Ring Protect Pro) qualify. Ask your insurer for their specific requirements — some need a certificate from the monitoring company. See our insurance discount guide for details.
Bottom Line
Best overall: Abode ($521 over 3 years, free tier available, unique codes per employee)
Best for retail: SimpliSafe ($2,126 over 3 years, but video verification gets faster police dispatch)
Best for cameras only: Reolink NVR ($450, zero monthly fees, 4K recording)
Commercial security pricing exists because businesses will pay it. You do not have to. A $300–$500 DIY setup protects a small business as well as a $3,000 commercial install. The sensors are the same. The monitoring stations are the same. The only difference is who screws the sensor onto the door.
