We know that security cameras play a vital role in detecting movement, recording video evidence, and catching criminals. However, their real power lies in crime prevention. In this article, we’ll explore the effectiveness of security cameras in deterring crime and how the right system—such as a covert outdoor security camera—can provide enhanced protection and peace of mind.

Do Security Cameras Deter Crime?
While no security system guarantees 100% deterrence, multiple studies and real-world data indicate that security cameras significantly reduce criminal activity. Whether through visible deterrence or providing valuable evidence when a crime occurs, security cameras are an essential tool for safeguarding your property.
When it comes to outdoor covert cameras, their discreet nature ensures that criminals are unaware they are being watched, providing a crucial layer of security without drawing attention to the surveillance setup.
The Case for Security Cameras
Research and Case Studies
- KTVB7 Study (Oregon): A survey of 86 convicted burglars revealed that most would avoid houses with visible security cameras or alarm systems. However, some viewed cameras as an indication of valuables inside. This suggests that visible cameras can be effective deterrents but must be part of a well-rounded security strategy.
Municipal Technical Advisory Service: A review of academic studies found that CCTV cameras significantly deter crime, especially when combined with other security measures like lighting. This highlights the effectiveness of covert outdoor security cameras as part of a broader security system.
- UNC Department of Criminal Justice & Criminology: A survey of 422 burglars showed that nearly 50% considered outdoor covert cameras and security systems to be major deterrents. Hidden surveillance cameras add an element of unpredictability, making it harder for criminals to bypass security.
According to the FBI Uniform Crime Reporting:some believe security cameras are too expensive to be worth the investment, even if they deter crime. However, wholesale security cameras are now more affordable than ever. For instance, the 5.0MP Tuya Smart WiFi/PoE Movable Dome IP Camera and Iufuture AI Smart Security Camera | 360° Auto-Tracking, Baby Monitor & Home Security are available at bulk prices as low as $20. Considering that the average property loss per burglary was $2,416 in 2017, investing in cost-effective, AI-powered surveillance can provide long-term security benefits at a fraction of the cost.
| Deterrence Measure Effectiveness | Overall % (rounded to nearest whole number) |
|---|---|
| Police nearby | 64% |
| Indications of alarms | 53% |
| Outdoor cameras | 50% |
| Outdoor lighting | 16% |
| Neighborhood watch | 13% |
| Security sign | 25% |
The Limitations of Security Camera Systems
While modern surveillance cameras can deter crime when functioning properly, multiple studies reveal significant limitations in their effectiveness:
1. Technical Failures Compromise Evidence
A Queen’s University study (2001-2003) documented 168 security camera failures that rendered footage unusable in court
Though smart home technology has advanced since 2003, equipment malfunctions remain a risk
2. Ineffective Crime Deterrence in Some Settings
Lincoln, Nebraska police reported zero criminal identifications from downtown bar district cameras
128 assaults occurred within 500 feet of operational cameras, showing no deterrence effect
3. Operational Limitations Impact Reliability
Urban Institute research found mixed results across cities:
✔ Reduced crime in Baltimore/Chicago business districts
✖ No impact in Washington D.C. or residential BaltimoreCommon surveillance system flaws:
Poor nighttime/weather visibility
Missed events due to incorrect camera panning
Incomplete incident coverage
Key Takeaways:
While security cameras remain valuable for property protection, their effectiveness depends on:
Regular system maintenance
Strategic camera placement
Supplemental alarm systems
Looking at those studies, more of them seem to prove that security cameras can deter burglars and crime. Except for the few inmates in the KTVB7 study that said security cameras can be a sign of a wealthy target, the consensus is that security cameras don’t encourage crime. We take that as a positive.
Besides that, the studies also show that when used with other security measures, you can boost the effectiveness of security cameras. The UNC research lists other things burglars deem effective as deterrents, such as:
- Alarm systems
- Outdoor lighting
- Security signs
Apart from that, our own experience in testing security cameras has shown us that security camera placement plays a crucial factor in keeping criminals at bay. So bottom line: It’s how you use your security cameras and other security equipment that deters burglars.

Signs and Systems
Just as two heads are better than one, a complete home security system with visible signs and alarms is better than just security cameras. A comprehensive security setup can make all the difference in deterring criminals. For a more complete security solution, consider pairing covert outdoor cameras with visible signage and alarms. Explore our B2B solutions for more information.
Visibility
While we don’t want to sound like a broken record, make sure that these security elements are visible to potential burglars, alerting them that your house isn’t worth the risk. Visible signs of security systems, including outdoor covert cameras, can significantly reduce the likelihood of a break-in. You can learn more about our covert outdoor cameras here.
Lights
Outdoor lighting, particularly motion-activated lighting, can literally shine a spotlight on criminals, increasing their visibility. Many cameras, like the IUFUTURE 1080P HD PoE CCTV cameras, come with built-in
Frequently Asked Questions
We’re not done yet! Here are the questions we get the most often about how security cameras, and other security elements, deter crime.
We’re not done yet! Here are the questions we get the most often about how security cameras, and other security elements, deter crime.
Burglars choose houses based on a number of factors such as the presence of:
- Cars in the driveway, especially if they’re luxury
- Big fences
- Overgrown bushes or trees
- Old or cheap window frames and doors.
They also consider the proximity to other homes, preferring more isolated homes to burgle. This data comes from a survey of 86 inmates for burglary at the Oregon Department of Corrections from local television station KTVB7.
Research from the University of North Carolina, Rutgers University, and the Urban Institute have found that CCTV cameras do deter crime.
Cameras are a good crime deterrent, as 60 percent of most burglars will choose another target if they find alarms or cameras, according to a study from the University of North Carolina’s Department of Criminal Justice & Criminology.
