Closed-circuit television (CCTV) systems may seem more old-fashioned than cloud-based security cameras, but CCTV systems have several upsides.
For starters, they allow you to connect all your cameras to one device. CCTV systems also use cables to connect directly to the hard drive, often leading to shorter loading times than you would get with a DIY system that connects to Wi-Fi.
Perhaps best of all, CCTV systems are often less expensive than purchasing multiple DIY security cameras. Check out our five picks for best CCTV systems under $400.
