Common questions
How many PoE cameras can it power?
It has 16 PoE ports and a 135W total PoE budget: ports 1-2 up to 90W each and ports 3-16 up to 30W each. Add up the power draw of your cameras and keep the total within 135W.
Are the PoE ports Gigabit?
No. The 16 PoE ports run at 10/100 Mbps. The two uplink ports (17-18) are combo ports, each either RJ-45 10/100/1000 Mbps or SFP 1000 Mbps. If every camera port needs Gigabit, see the DH-CS4228-24GT-375.
Can I use fibre for the uplink?
Yes. Each combo uplink can be used as an SFP 1000 Mbps optical port instead of the RJ-45 port.
Do I have to use the cloud app?
No. Dahua lists web management as well as app management, and cloud management goes through the DoLynk Care app.
How far can a PoE port reach?
Dahua says up to 250 m, with the bandwidth reduced to 10 Mbps at that distance.
Can it be rack mounted?
Yes. Dahua lists desktop mount and rack mount, in a sheet metal case.
