Hi All,

we are looking at intergrating the CCTV systems in an out lying depot to stream to our main Centre control room. The problem is the distance is 1.33Km Direct line of site for the two control rooms. We are looking at what possibilities we have of streaming the video across. Neotel and cable will be too expensive so we are maybe looking at long range wifi. I believe you can get long range antennas to do this.

Can anyone tell me what is available and what laws and restrictions I would have to worry about?
 
The distance is not a problem for wifi there are many that do much longer links but how much bandwidth will you need?
 
Probably around 30 Cameras streaming 1080p HD Video. The connection will be crossing a road, but I am unsure if the Road belongs to my company or if it is a community road. How would I find out if I need a License?

Talk with ICASA. They manage the licenses. It depends on your frequencies/crossing boundaries.
 
Eish!!!
You only need a licence if you going to re-sell bandwith on your wifi link.
Crossing a road is also fine, fence, building, ect is also fine.

1,33km is not the problem.
The real question is the amount of data you looking to transfer.
Is it only a single camera, or is there more than one?
If you have multiple camera's, the best would be to install a DVR on the remote side and then only use the wifi to monitor.

First find out what the bandwidth requirements are for the CCTV stream. I would also go with just viewing a remote client from the monitoring room side rather than streaming all cameras. That way if the link fails, it will still continue recording on the remote side.

Options I would look at which are fairly inexpensive would be a Mikrotik dual N-Stream option which should give you more than sufficient bandwidth for remote viewing.

Other options would be Ubiquiti/Radwin depending on bandwidth requirements.
 
Hi all,

I worked out that we would need around 300Mbps bandwidth. There is a manned control room at the remote depot that we want to do away with. There are also PTZ cameras that will need to be controlled from the main Centre. The whole idea is to move control away from the remote depot and have the storage at the main centre with a fail over at the remote center to keep recordings. I am not sure if we would be able to pull recordings when just viewing.

Is the plan to view all cameras at the same time or focus on priority cameras only?
 
300mbps is not too bad the best bet is to go to a place like miro or scoop etc and have a chat with someone who deals with this on a daily basis. But what you are asking for is totally achievable with some or other wifi bridge.
 
For 300mbs I would only recommend a 17ghz 30cm dish link that can do full duplex. The ubiquiti and mikrotik ac kit is good for 100-200mbs but is not full duplex and it is still in the 5ghz spectrum.
 
Hi

I spoke to Scoop Distribution in Durban and they suggested I use the

Nanobeam NBE-519AC

Cost is not too much of a factor if it is once off I would like your guys opinion on this?
 
The Nanobeam NBE-519AC should do the trick, considering your alignment is up to scratch. -50/-50 and you're golden.
 
Agent_B would like lto know on what you settled with.
Am sitting with possibly a similar scenario.

AirFibre is full duplex so probably the cheapest FD kit you can buy. AirFibre X is half duplex so do not get confused.

They were talking about the ac kit....not airfibre.

Yup not correcting your post just making a suggestion to the thread as 17GHz is great but 5GHz in a park for example will be fine as the interference is manageable. Well should be.. 17Ghz price tag is steep and 5GHz AirFibre half of that.
