“I’d personally go with a security camera WITH alarms rather than alarm systems. These will all record and alert you to movement.”

“I suppose it would be nice to use the wireless security cameras with audio alarms, i.e: when a camera detects motion, not only it triggers email with camera details, but also siren sound and GSM text/phone composing.”

Security cameras with alarms, by sending real-time alerts and recording crucial snapshots or videos of invaders, offer superior protection for your property.

In this blog, you will figure out how wired and wireless security cameras with alarms work, what alert options are, best picks of security cameras with alarms and how to avoid false alarms.


How Security Cameras with Alarms Work

Security cameras with alarms, in light of different motion detection sensors equipped with them, can be divided into two types.

The first type of security cameras with built-in alarms relies on software-based motion sensors. They detect motion by comparing a sequence of frames and counting the number of different pixels.

When pixel changes between successive frames, the software inside home security cameras with alarms will count it as a motion event and set off the alarms.

Reolink RLC-410 surveillance camera with alarms belongs to this type. And its working process is showed in the following illustration.

The second type of IP security cameras with alarms is PIR (Passive infrared) movement sensor cameras that passively receive and detect infrared radiation from the surrounding.

Once a foreign body like a burglar trespasses, the PIR sensor would identify the differences of radiation and alarms ensue.
