Estimate an equipment and installation range based on system type and number of devices.
Use this estimator to turn a device count into a rough one-time budget. Pick the system type, enter how many devices you expect (door and window sensors, motion detectors, cameras, keypads, sirens), and add a one-time amount for the hub or control panel and any activation or installation fee. The calculator multiplies the quantity by a low and a high per-device cost, adds the fixed amount, and shows a range.
Formula: low total = quantity x low unit cost + fixed amount; high total = quantity x high unit cost + fixed amount. The per-device ranges built into the system types are illustrative and deliberately wide. You can overwrite the low and high values with prices from real quotes.
Worked example (illustrative): 10 devices at 25 to 80 dollars each, plus 150 dollars for a hub and setup, gives a low total of 10 x 25 + 150 = 400 dollars and a high total of 10 x 80 + 150 = 950 dollars.
Limits: The result covers one-time costs only. It leaves out monthly monitoring, cellular or internet fees, permit costs and any equipment you will add later. Add those with the contract cost calculator before comparing providers.

How much a home security system costs in 2026: equipment, installation, monthly monitoring and contract terms, with illustrative ranges and a simple way to add them up.
Getting Started and Using It
How renters and apartment dwellers can add home security without damaging walls or breaking a lease: wireless kits, door devices, cameras, permissions and costs.
Pricing and Comparison
Home size, number of entry points, system type, monitoring features, cameras, contract length and location all change what a security system costs. Here is how each factor works.
