NVR buying guide: channels, bandwidth, hard disks and PoE
An NVR (network video recorder) records IP cameras to a hard disk. Choose it by how many cameras it takes, how much video it can pull in at once, how much disk it holds, and how the cameras will get power. For picking the cameras themselves, see the Hikvision camera buying guide on Hikvision camera price in Nepal.
1. Count the channels, then check the bandwidth
The channel count is how many IP cameras the NVR records: 8 on the Hikvision DS-7108NI-Q1/M, 10 on the Tiandy TC-R3110, 16 on the DS-7616NI-K1 and DS-7616NI-K2, and 32 on the Tiandy TC-R3232. "Port" in these product names means channels, not network sockets. Leave a few spare, because adding a camera later is easy and replacing the recorder isn't.
Incoming bandwidth is the second limit, the total video the NVR can take in. Hikvision gives the DS-7108NI-Q1/M 60 Mbps (Hikvision) and the DS-7616NI-K1 160 Mbps (Hikvision), and Tiandy gives the TC-R3110 60 Mbps (Tiandy). Add up the bitrates your cameras are set to and keep the total under that figure. For example, eight cameras at 6 Mbps each come to 48 Mbps, which a 60 Mbps NVR handles. Sixteen at the same setting need 96 Mbps, which calls for the 160 Mbps DS-7616NI-K1.
2. Match the camera resolution
The NVR also limits how sharp the cameras can be. Hikvision rates the DS-7108NI-Q1/M for cameras of up to 6 MP, with full-channel recording at up to 4 MP (Hikvision), so it pairs best with 2MP to 4MP cameras. The DS-7616NI-K1 records up to 8 MP (4K) and has a 4K HDMI output for the monitor (Hikvision), and Hikvision's K2 datasheet lists 8 MP too (Hikvision), so choose the K1 or K2 for 4K cameras.
Playback has its own limit, which Hikvision calls decoding: how many cameras the NVR can show at full quality at the same time. The DS-7108NI-Q1/M manages 4 at 1080p or 2 at 4 MP (Hikvision), and the DS-7616NI-K1 6 at 1080p or 3 at 4 MP (Hikvision). It matters if you like to review several cameras side by side on the monitor. Hikvision lists H.265+ and H.265 on its NVR datasheets, and Tiandy lists H.265 for the TC-R3110 (Tiandy). H.265 stores the same picture in less space than the older H.264.
3. Hard disk bays and how many days you keep
The DS-7108NI-Q1/M takes one disk of up to 6 TB (Hikvision), the DS-7616NI-K1 one of up to 8 TB (Hikvision), and the Tiandy TC-R3110 one of up to 8 TB (Tiandy). The K2 has a second bay: Hikvision's datasheet for the DS-7616NI-K2/4G lists 2 SATA interfaces at up to 8 TB each (Hikvision), and the TC-R3232's name says 2HDD. Use a surveillance hard disk, made for recording all day; see internal hard disk price in Nepal.
To size the disk, multiply out the bitrate. Eight cameras recording nonstop at 3 Mbps write 8 × 3 × 86,400 ÷ 8 = 259,200 MB, about 259 GB a day. That's about 15 days on a 4TB disk, about 30 days on 8TB, and about 60 days with two 8TB disks in a two-bay NVR. Recording only on motion stretches it much further.
4. Power the cameras with a PoE switch
Hikvision's datasheets for the DS-7108NI-Q1/M and DS-7616NI-K1 list no PoE ports, only one network port (Hikvision, Hikvision), and Tiandy lists none for the TC-R3110. With these recorders, the cameras plug into a PoE switch, which powers them over the network cable, and the switch connects to the NVR and your router. Add up the cameras' maximum power from their spec sheets and keep it within the switch's PoE budget. See PoE switch price in Nepal.
For recording to carry on through a power cut, put the NVR, the PoE switch and the router on a UPS. The NVR itself draws little: Hikvision lists 10 W or less for the DS-7108NI-Q1/M (Hikvision), and the same for the DS-7616NI-K1 without a disk (Hikvision). See UPS price in Nepal.

NVR FAQ
What is the difference between an NVR and a DVR?
An NVR records IP cameras, which connect by network cable and usually take power over it from a PoE switch. A DVR records analog HD cameras on coaxial cable. If you're putting in a new system with IP cameras, you need an NVR.
What does "16-port" mean on an NVR?
It means 16 channels, so the NVR records up to 16 IP cameras. The Hikvision DS-7616NI-K1 has one network port, so its cameras connect through a PoE switch.
How much hard disk do I need for an NVR?
Work it out from your cameras' bitrate. Eight cameras recording nonstop at 3 Mbps fill about 259 GB a day, so a 4TB disk keeps about 15 days and an 8TB disk about 30. Motion-only recording lasts longer.
Which NVR brands do you sell?
Hikvision and Tiandy. Every price on this page is our current website price.
