They are the newest system type and are capable of supporting video with 4K resolution (above 1080p).

Network IP Systems operate over standard CAT5/6 Ethernet cable.

Also called HD over coax, they are considered the industry standard for modern HD surveillance.

HD-CVI Systems operate over coaxial combo cable with BNC connections.

They are the most cost-effective type, but have a limited zoom resolution.

Traditional Analog CCTV Systems operate over combo RG59 / siamese cable.

See our dedicated page on choosing the right system for more details. Each operates over a separate type of cable and supports different types of camera technologies. There Are 3 Types of Security Cameras & Systems

Continue through our security camera buying guide to see all of our HD options. The best thing about HD cameras is that you can digitally zoom while keeping the quality largely intact, rather than looking a bit blurry or pixelated. The higher the megapixel count of the camera, the sharper the image. An 8MP camera produces up to 4K ultra HD video. 2MP resolution is equivalent to full HD 1080P. With modern technology, HD cameras and recorders are even cost comparative with traditional analog models.ġ megapixel (MP) resolution and above is considered high definition and is 720p. HD cameras offer at least 3-5 times better clarity than the standard analog cameras. High definition cameras deliver the video resolution you need to make out fine details like license plates and faces in your surveillance footage. If you are considering a new system or upgrading an old one, our comprehensive security camera system buying guide can show you what’s out there and where to start. Now that we know the difference between how NVR and DVR systems works, let’s look at what those differences mean in terms of pros and cons of each system.Security cameras are an essential investment in protecting your business, place of work, or personal property. After connecting to a smartphone or any other viewing device, you can easily access and view your video footage as needed.

Once the video is processed, both DVR and NVR systems work the same. From there, the recorder processes the video footage. Instead, the analog cameras stream raw video footage to recorders via coaxial cables. Unlike an NVR system, DVR systems work with analog cameras, which can’t process video footage. These systems are considered the older “legacy” option. They do so using either an ethernet cable or wirelessly via an existing WiFi network.ĭVR stands for Digital Video Recorder. IP cameras can actually capture and process video and audio data themselves. These systems work with an advanced type of camera, called IP cameras.

NVR systems record and store video footage directly from the network it lives on.
