Does video surveillance make a home more secure? In general terms, yes. Theoretically, a thief could note a home's level of video surveillance, assume that there must be a number of high-value possessions inside to warrant this level of surveillance, and may redouble their efforts to break in. But this scenario is unlikely, and in most cases, video cameras will act as an effective deterrent to would-be thieves. Of course, not all forms of surveillance offer the same standard.
Dummies
It could be argued that even dummy cameras (or more accurately, camera housing without anything inside) affixed to the exterior of a dwelling at strategic, highly-visible spots would make a difference. But this difference is so minimal that it's barely worth the time it would take to install these dummies. And in any event, an experienced criminal could conceivably tell the difference.
Closed Loop
Basic security cameras operate on a closed-loop system, constantly recording their field of vision. This has limited value from a security standpoint. The images must be continually monitored for an immediate response to anything that seems out of place, with the footage sent to an onsite digital storage device (hard drive), where it will be regularly purged once the device reaches its storage capacity. This system may be able to provide law enforcement with an image of any thief after the fact, but this is about it—and is perhaps too little, too late.
Monitored Systems
A form of monitored security camera is the next step up, and this needn't be expensive. Motion-activated systems are perhaps more common than the (increasingly outdated) closed-loop system. Any type of monitoring usually requires a subscription fee, but this won't be exorbitant, since many of the system's key features are automated. What features does such a system need?
In Action
The system can be calibrated to detect specific threats. It won't continually record, but will activate once something of a predetermined size enters its monitoring field. For example, you can make sure that only something human-size activates the system, and not your family cat. This activation can send a push notification to an app installed on your phone. This creates a live link to the camera feed. You can see what's happening, and proceed accordingly—calling the authorities as needed. The system is monitored, but these duties are shared between you and a computer system.
Advanced, partially automated forms of video surveillance are more accessible than ever. It doesn't take much to considerably upgrade your home's security, thereby downgrading its appeal to a thief.
