Dear all networking aficionados
I am new to networking and I need to set up a link for 35 Km for CCTV surveillance of 32 IP cameras. I have been reading this forum for a couple of weeks and I would be grateful if you could, kindly, help me in .
I was thinking to buy NetMetal 5+Kenbotong 32.5 dbi (Dual polar) for each side. But, I am not sure if that would work. My questions are what is the difference between NetMetal and BaseBox and which one do you suggest? waht is the advantage of buying RB433AH and assembling devices myself? Also, is it possible that after buying these devices the link could not be established and I have to buy another set of devices? Lastly, can I learn how to install them by reading over the forum and some books in a couple of weeks or I have to hire someone?

I appreciate all your responses beforehand

Come on guys. No one has any opinion or advice?

Hello, i have never done this link like this before, but you need 100% freshnel zone.
How much bandwith do you need ?

Hello, i have never done this link like this before, but you need 100% freshnel zone.

So, you think it is very distant? Hopefully, except for the first 500 meters, the rest are agricultural lands and getting 100% fresnel zone is possible by moderate towers at both ends. Regarding the bandwidth the more is the better and I can see the cameras with more frame per seconds, but I would like to have a minimum of 50 Mbps. Any suggestions?

I think a new 802.11 ac link with 20Mhz channel bandwith should be ok.
I am not an expert but Mikrotik 30dBi new dish antenna should be ok with a Netbox 5

The signal strenght should be around -65dBm. But you know, this is just a theory, and in the wireless networking you really need 100% clear line of sight and fresnel zone.

Or there is a Jirous dish antenna like this:

I think if you need at least 50 Mbit/sec this kit would be ok.

As you can see Jirous and Mikrotik provide a box for the routerboards behind the antenna.

Hi, Thank you for your comment. Could you please let me know what is the difference between Netbox 5 and Netmetal 5? I assume since the price of Netmetal is higher, it is more strong and thus, more appropriate for me. Please correct me if I am wrong.
Aslo, Unfortunately in my country only Kenbotong dishes are available.

Netbox has a plastic enclosure, Netmetal has a metal enclosure. Netmetal also has sfp slot.
And they both have 3 vesrions - version with an additional pcie slot, high power version, triple chain version.
For this link best is to choose the high power version :
NetMetal Dual Chain Super High Power 2000mW (RB921UAGS-5SHPacD-NM)

I do not know Kenbotong, it is similar like other dishes, 32 dBi, so should be good for this distance.

Thank you for your comments. So I would go for NetMetal 2000mW. But as my last question, can someone tell me the advantages of buying RB433AH and assembling devices myself? what is this good for?

Let me share my situation. We have link which is 24 km. From hardware there is 2x RB433AH's and 2x30Dbi dishes.
I had little problems with strange disconnects, you can see it in my topic here. Little tuning and useful advices and link is stable now. I can get about 30-40 Mbps. At the moment, the best solution that i can recommend is 433AH. You can check other vendors for their solutions for 50+km but it's not cheap, ofc.

433AH is a strong device. Are you using 802.11 N ?

Thank you. But, since the price of 433AH is more than twice that of NetMetal, I would like to know the difference between them. what does 433AH does that NetMetal cant do? I prefer to know what I am paying for, before purchasing. So, in your experience why didnt you use NetMetal?

433AH is a strong device. Are you using 802.11 N ?

I have not yet bought the devices. I am still trying to figure out what to buy. So, I dont really get what you meant by 802.11 N ??
Also, would you please give more details on the word "strong". is 433AH suitable for longer distances or it provides more bandwidth compared to the NetMetal.

433AH is a good device, but is an old model now. The cost is high because you buy the board, then have to buy a wireless card, some box.
The advantages are that is has 3 slots, but they are minipci slots, as opposed to the new pcie slots. Also has 3 ethernet ports. For a long time it was a very good option because it has 680mhz processor, but the Netbox has newer and 720Mhz processor.
The bandwidth is very much dependant on what card you will install in the 433ah, but I don't think there are .ac cards on minipci form factor, just pcie. So bandwidth wise it cannot go as high as Netmetal.
So unless you need more than 1 wireless card and more ethernet ports you are far better of with the Netmetal (Netbox).

Just following what Tod said, at that time, 433AH was best buy. Reliable, strong, and mixed with powerfull cards and dish, you could achieve stable long distance links.
I really didnt look for netmetal and now im reading its specs...it looks pretty damn good for that money.
One thing that concerns me the most is this line in description of product from Mtik page:Suggested for High-Speed links on short distances (under 1km)

Sorry, i asked from TomosRider

How have you decided ?

Anyway i read about a 46 km link 3 years ago, and that was capable of 45/45 Mbit/sec TCP speed with DBii card and 34 dBi Ubiquiti Rocket dish and with 435G. The signal travelled across the sea.
