Wired vs. Wireless Alarm Cost

Alarm systems typically include a control panel, keypad, battery backup, window and door sensors, motion detector, and window decals, and yard signs.

Wired vs. Wireless Alarm Systems
  Wired Wireless
Cost $800 – $1,600 $200 – $2,000
  • Lower maintenance, and less expensive components

  • Can provide zone control - Upstairs / downstairs
  • Sensors don’t require batteries
  • More reliable in areas with bad cell service
  • Can convert to a self-monitored home security system that connects to 911.
  • Easy DIY install; no drilling or wiring
  • Ideal for new or small homes, renters, or historic buildings without existing wiring
  • Easy to install or more
  • Works during power outage
  • Connects with home automation systems
  • Control panel access via smart phone or website

Hardwired systems can have wireless sensors or cellular backup. Converting a hardwired system to wireless costs $50 to $170 for parts, plus fees for installation by a professional. Companies like Link Interactive, Brinks, and Xfinity will take over existing systems and provide monitoring.

Alarm System Activation Fees

Security system activation fees range from $0 to $300, with most homeowners spending $25 to $100 on average, depending on the security provider, alarm type, and plan selected. An activation fee is a one-time charge paid up front to activate your home security system.

Companies that don't have an activation fee may charge more per month. Hidden activation fees are found in the fine print of the contract.

Home Security Monitoring Cost

Home security monitoring costs $15 to $35 per month on average. Adding monitored security cameras costs $15 per month more, and smoke or carbon monoxide detectors add $2 to $6 per month. Monitoring services:

  • Automatically alert police, fire, medical response teams

  • Detect carbon monoxide, smoke, and natural gas leaks

  • Monitor power outages, flooding, and changes in temperature

Home security monitoring cost - chart

Home Security Monitoring Cost
Service Average Cost
Base Monitoring $15 – $35
Monitored Security Camera + $15
Monitored Smoke or Carbon Monoxide Detector + $2 – $6

Wired systems use landlines to communicate, while newer systems use cellular or broadband.

  • Landline – Cheaper, requires a telephone line. Currently being phased out. Landlines are less secure and easily compromised by cutting the line. Be sure the system includes a cellular backup. Landlines can be converted to broadband / cellular systems for $80 to $330 or redirected to another provider.

  • Broadband / Cellular – Offers the safest and fastest protection using an internet connection or cell service. However, backup power is required since power outages affect cellular and broadband systems with Wi-Fi sensors.

Home Security System Features

The extra features and fees vary depending on the security provider:

  • 24/7 Live Camera Recording – Security cameras and video doorbells with motion-triggered or continuous video recording (CVR) and cloud storage of 7 to 30 days

  • Remote Monitoring – 24/7 professional monitoring. If a sensor is triggered, the remote monitoring center will alert you of suspicious activity.

  • Smart Home Monitoring – Some companies offer plans to connect the security system to operate smart lights, smart locks, doorbells, and thermostats to automatically lock doors or adjust the home's temperature.

  • Smash Crash Protection – A burglar can’t smash the system to disable it.

  • Triggered Sensors – Smoke, carbon monoxide, extreme temperature, flood, motion, window, and door sensors can send automatic notifications when triggered.

  • Phone App – Control, monitor, and arm/disarm the system remotely from your phone.

  • Panic Button – Add an instant alarm activation in any room to bring 24/7 emergency help. Key fobs and wearables are also available.

  • Emergency Response Plan – Trained agents offer guidance during an emergency. You can also choose to contact authorities or a third party automatically.

  • Duress signal – You can enter a code when under duress to alert the monitoring center that you need help but are unable to be contacted.

Homeowners Insurance Discount for Security System

Having a security system lowers your homeowners insurance, with typical discounts between 5% and 20%. An alarm system lowers your insurance bill by $60 to $240 per year or $5 to $20 per month.

Plus, ADT covers up to $500 of your deductible if a burglary occurs while your ADT alarm is armed.

Who Installs Home Security Systems?

Independent alarm companies, electricians, and handymen install home security systems, depending on the type. Another option is to purchase the equipment and install it yourself.

Do You Need a Permit for a Home Security System?

It's legal to install your own security system without getting a home alarm permit. However, many local laws require an alarm permit for systems with remote monitoring or emergency service dispatch. Some companies refuse to install the system until a permit number is provided.

Is a Home Security System Tax Deductible?

A home security system is not tax-deductible unless you run a business from your home. If you install a whole-house security system that protects all the windows and doors, you can deduct the business portion of the expenses incurred to maintain and monitor the system.

Can Home Security Systems Be Hacked?

Get free estimates from home security companies near you.

Home security systems are hacked by jamming radio frequencies to block sensors, cutting landlines, or shutting off power. Security cameras are hacked through vulnerabilities in the camera, Wi-Fi router, or network switch. Most breaches are due to outdated firmware and default passwords and settings.

Hiring a Home Security Company

Before hiring a home security company, be sure to compare prices, read reviews, and read the contract in full. Ask providers to explain anything you don't understand in the contract. Also, check if the company is a member of known security associations and is licensed to do business in your state. Learn:

  • If contracts are required and how long they are for.

  • If the monthly fee becomes cheaper once the equipment is paid off and the contract is over.

  • If you can see the contract in full before becoming a customer.

  • If you’ll be provided with the details of every charge before you sign a contract.
