Research I'm doing on home security/alarm systems in January 2025.

Much of the information in this section comes from ChatGPT.

• Size of Your Home: Larger homes may require more sensors, cameras, and equipment to cover all entry points.
• Specific Risks: Consider what you’re trying to protect—e.g., are you concerned about break-ins, fire, carbon monoxide, or flooding?
• Entry Points: Identify doors, windows, and other vulnerable areas that might need monitoring (e.g., basement, garage).
• Smart Home Integration: If you have a smart home or plan to add smart devices, choose a system that integrates with other smart technologies (e.g., thermostats, lights, voice assistants).

There are different types of security systems, each with its own benefits:

• Monitored Systems: Connected to a central monitoring station that alerts authorities if an alarm goes off.
  • Pros: Immediate response and professional monitoring.
  • Cons: Ongoing subscription fees.
• Unmonitored Systems: Alerts only you or designated contacts (via app or loud siren).
  • Pros: No monthly fees.
  • Cons: You are responsible for responding to alarms and contacting authorities if needed.
• DIY Systems: Self-installation systems, typically designed for easy setup and maintenance.
  • Pros: Low upfront costs and flexibility.
  • Cons: Might lack advanced features or professional monitoring.
• Professional Systems: Installed and monitored by a company.
  • Pros: Expertise in installation, ongoing monitoring, and service.
  • Cons: Higher costs due to installation fees and monitoring subscriptions.

• Control Panel: The central hub of the system, usually wall-mounted, from which you can manage settings, arm/disarm the system, and receive notifications.
• Sensors (Door/Window): Detect unauthorized entry. You’ll need them on all doors and windows that are accessible.
• Motion Detectors: Placed inside the home to detect movement after the system is armed.
• Cameras (Indoor/Outdoor): Surveillance cameras to identify suspects and provide evidence in case of a break-in. Some systems offer cloud storage for video footage.
• Smoke and Carbon Monoxide Detectors: Integrated into the system to detect environmental hazards.
• Panic Buttons: For alerting authorities in case of an emergency, without using the phone.
• Keypads and Remote Access: Ensure the system offers a keypad or mobile app for easy arming/disarming.

• Reputation and Reviews: Check online reviews, testimonials, and ratings from reputable sources (e.g., Consumer Reports). Word-of-mouth recommendations can be helpful.
• Monitoring Services: Compare response times, customer service, and support offered. Some companies offer 24/7 monitoring, while others only operate during business hours.
• Contract Terms: Many companies require a long-term contract for monitoring services (typically 2-3 years). Understand the terms, fees, and cancellation policies. Some companies offer no-contract options, often with higher upfront costs but more flexibility.
• Installation Costs: Installation fees can vary. Look for companies offering free installation or check if DIY options are available.
• Customer Support: Ensure the company offers reliable customer service via multiple channels (phone, email, chat).
• Technology: Look for systems that integrate with smart home devices (e.g., thermostats, lights, voice assistants).

• Upfront Costs: Includes equipment costs, installation fees, and possible upfront subscription charges. DIY systems often have lower upfront costs.
• Ongoing Monitoring Fees: Professional monitoring costs typically range from $10 to $60 per month, depending on the equipment you have and the extent of monitoring you want.
• Additional Fees: Watch for potential add-on costs for cameras, sensors, or advanced features.

Here are some well-known security system companies:

• ADT: One of the most popular and established names, offering professional monitoring, a range of equipment, and flexible contract options.
• Vivint: Known for smart home integration, Vivint offers professionally installed systems with home automation features, though it tends to be on the pricier side.
• SimpliSafe: A highly regarded DIY option with flexible monitoring plans. Easy to install and offers no long-term contracts.
• Frontpoint: Offers DIY security systems with monitoring options. Known for good customer service and high-quality equipment.

• Ring Allows self-monitoring without monthly fees; can arm/disarm remotely; can be expanded; has backup battery; works over Wifi with cell backup

• DIY Security Systems: (e.g., SimpliSafe, Ring, Abode) These are simpler to install and have fewer installation costs. However, they may lack advanced features or professional monitoring.
• Professional Installation: (e.g., ADT, Vivint, Frontpoint) These systems are more expensive but ensure correct installation with optimal coverage and configuration. Professional monitoring and ongoing support are often included.

• Backup Power: Ensure the system has a battery backup in case of a power outage.
• Cellular Backup: Keeps the alarm system active if your home phone line is cut.
• Home Automation: Some systems allow smart home control (e.g., thermostats, locks, lights).
• Smartphone App: Ensure the system lets you monitor, arm, and disarm remotely via an app.

• Homeowner’s Insurance Discounts: Many insurers offer discounts for homes with monitored security systems.
• Permit Requirements: Some cities or counties require a permit for monitored alarm systems. Check local regulations to avoid fines.

All commercial and residential alarm systems in Lexington MA must be registered with the Police Department. Use the registration form

Your choice will depend on your specific needs, budget, and whether you prefer professional installation and monitoring or the flexibility of a DIY system. Start by assessing the level of protection you want, then research companies and compare equipment to find the best fit for your home.

And this on Protecting your home from the Lexington town website.

• [Lex resident comment] These services are usually provided by small local businesses that help to maintain the security and safety of a home while you are away, either traveling or staying at another home. They offer a range of coverage from a simple on-call “key holder” to regular weekly walk-throughs, watering plants, (re)stocking refrigerators, etc.
  > All these businesses must be vetted and registered with the state police, and there are a limited number of options depending on your location. We use two services for our two homes, one in Lexington and one in Gloucester. They have been very helpful when a smoke alarm goes off (broken alarm sensor) or a when storm blows through and we want to be sure no serious damage has occured. They even spotted a frozen faucet for us once.
  > In Lexington, we use The HouseWatchers, but there is at least one other service if you google “house watch services lexington ma”.

I found a company online (Alarm System Store) that sold alarm components direct for DIYers. They were very helpful via their support chat and I ended up buying a new panel, keypads and some motion sensors from them. I also installed a plug-in device called Envisalink from Eyezon company. That device plugs into the alarm panel and home Ethernet and allows control via a phone app or web URL. It basically emulates another keypad in the system and as such it has control over all functions.

Installation was pretty straightforward, but I found some mistakes in the initial alarm wiring that I had to address. I also decided to use Eyezon (the company that made the plugin device) for their alarm monitoring service. The basic rate is $8.50/month. I added on their cellular communicator device as well in case the home network goes down. I think there's an additional $5/month charge to support that but it seemed worthwhile.

I'm sure there are newer options available and there's always SimpliSafe, but I thought using my hardwired motion detectors and door sensors was better than constantly changing batteries. So far, I'm happy with the setup.
