We wanted to add surveillance at the warehouse so we don’t have to go out there to check on things as often. We purchased an adt camera package and it has really helped cut down on our travel time. Simple but effective way to add surveillance to our storage warehouse."

FAQs for home security system service projects in Greenville, NH
The average cost of a home security system is about $700, ranging from $280 to $1,150. Costs to consider include equipment, surveillance fees, and other additional features. Cost factors that determine your system’s price include the type of security system, materials, labor, activation fees, monthly fees, and permits. Additional features and upgrades may include:
Video surveillance monitoring: $40–$65 per month
Smart home locks: $150
Smart home lighting: $15–$90
Smart smoke, fire, and carbon monoxide alarms: $35–$100
Smart thermostat: $130–$500
Yes, a home security system can be worth it for your peace of mind alone, but it can also save you up to 20% on your home insurance. The insurance savings will help defray the initial setup costs and subscription costs over time. Locations with higher crime rates also make home security systems a valuable investment, but it ultimately depends on your personal preferences and asset values.
With the popularity of DIY security cameras and video surveillance systems, it’s important to understand the benefits and potential drawbacks to decide if it’s the right choice for you. Advantages and disadvantages include:
Pros
Video footage readily available
Reduced home insurance
Save on labor costs by installing security cameras yourself
Wireless systems are easy to move and set up
Monitor from your smartphone
Avoid false alarms
Cons
Features may be vulnerable to hackers
No direct link to authorities
Risk of installing the system improperly, reducing its effectiveness
Whether a security system or security cameras is a better choice for you depends on your needs and preferred comfort level. A security system can cost more depending on the features you choose, but it’s a more proactive and protective approach to home security by alerting you and authorities of any emergencies. Using a security camera system is a more reactive approach because while you can monitor the camera footage, it does not alert the proper authorities for you.
Understanding the pros and cons of installing a home security system is the first step to deciding which one is right for you. A few of the advantages and disadvantages include:
Pros
Added security for your household
Reduced home insurance premiums
Many smart home integrations available
Security companies can monitor your home
Cons
Expensive setup costs
Subscription costs can add up quickly
Features may be vulnerable to hackers
Weak signal reduces the security of a wireless system
