FAQ
Which is better, NVR or DVR?
For most modern setups, an NVR is considered the better long-term option. DVRs (Digital Video Recorders) work with analog cameras, making them more affordable but with limited video quality and flexibility. NVRs (Network Video Recorders) use IP cameras, which generally provide higher resolution, more smart features, and easier remote access.
Can I use an NVR without a router?
Yes. An NVR can work as a closed system by connecting directly to your IP cameras via Ethernet. However, without a router or Internet connection, you won't be able to access the footage remotely or receive alerts on your phone.
Does an NVR need a hard drive?
Yes. Most NVRs need a hard drive to store video recordings. Without one, you can still view live footage, but you won't be able to save or review past events. eufy's NVR security system comes with a pre-installed 2 TB hard drive and supports expansion up to 16 TB.
Will any camera work with an NVR?
No. NVRs typically work best with cameras from the same brand, especially if you want to use all the features. However, many NVRs support ONVIF-compliant IP cameras, which allows compatibility across different brands.
Do eufy NVR systems have monthly fees**?
No, eufy NVR systems don't come with monthly fees. Once you purchase the NVR and security cameras, recording is handled locally on the hard drive.
