Network video surveillance reconfiguring

[riahc3 0]

Hello

 

We plan to put 8 wifi (or PoE if the cost permits it) IP cameras in our network. I imagine that will take a hit on performance....

 

I plan to put a dedicated access point for it (wifi or PoE) but I still think 8 at 720p will saturate our network. Im looking for ones that are 802.11ac but I find very little so I imagine Ill have to go with 802.11n

 

Also, since we have to reduce bandwidth, Im stuck between subnetting my network or VLANing it. We will have our office on one side (default and/or tag 1) and our cameras (nondefault and/or tag 2). I say "default" because we have network equipment in remote locations and those should automatically use the default one since they cannot be configured.

 

Should I go with subnetting or VLANs? Will this reduce network congestion and allow better performance for the office?

 

Any other things I should take in account for? Im still looking for IP camera recommendations.

 

Thank you

Wireless cameras, in general, are not reliable, I'd go hardwired/PoE except for special circumstances(like outdoors long distance point-to-point link). 8 cams on a gigabit wired network should not be much of a performance hit, would consume maybe 30-50mbps depending on resolution/encoder settings.

 

VLANs/subnetting will not reduce congestion as you are still sharing the same transmission medium, its more about security/isolation but if you have a lot of devices then subnetting will reduce broadcast traffic.

It would be 8 cams and at a 720 resolution.

The bold part is what I had in mind For this is VLAN and subnetting the same?
