by
Two-Way Audio Cameras Work

Two-way audio cameras do more than just record sound. They also allow you to communicate with people through the camera.

Security cameras with two-way audio have become increasingly popular, especially among smart camera users. I’ve also noticed growing demand for this feature. In fact, some potential customers specifically ask me whether the camera they’re about to purchase supports two-way communication.

In the past, adding two-way audio to a security camera system often required a manual setup using additional accessories, such as an external microphone and speaker. However, things are much simpler today. Many modern security cameras already have both a microphone and speaker built in, so you can listen and talk directly through the camera using your smartphone.

Hikvision Quick Pass—Easier Access Control for People and Vehicles—Everything You Need to Know

by
Hikvision Quick Pass

Traditionally, access control systems rely on credentials like access cards, fingerprints, and vehicle license plates to grant entry. While these methods are still widely used, they’re considered less secure in today’s AI-driven world.

Someone using an access card might not be the person it was originally issued to. Fingerprints can also be shared. I’ve even tested this myself by enrolling fingerprints from two different people, only to find that both could use them to gain access. The same goes for license plates. Someone could simply transfer a license plate to another vehicle, and the system might still recognize it as valid, allowing a stolen car to leave the building without raising any alarms.

Hikvision aims to reduce these risks with its Hikvision Quick Pass solution.

Installing Frigate NVR on Linux Ubuntu—My First Experience to Install Frigate on Ubuntu Using Docker Compose with Limited Technical Skills

by

Frigate is a virtual NVR that you can self-host on your own computer.
