Will This Work? Hikvision Encoders + 128 Channel Recorder

Yes, once the signal is encoded it's able to be broadcast over a network. 

Main thing is to be mindful of the total bandwidth you're sending from A to B and that your medium is sized appropriately. 

The thing I would be mindful of is the performance of the 128 channel recorders. They're notoriously unreliable and troublesome.

Had an integrator use them in a large install and got thrown out after a year due to reliability and stability. You're better off stacking the 32s. 

If this is a large office complex expect they might already be using the 5 Ghz frequencies for a AC wifi system. Unless you can get them to lock out the frequency you want to use in the Nanobeam system you will have random outages when the 2 systems land on the same channel. You could become the IT department enemy real quick. 

Also keep in mind if you go to maximum thruput speed on the nanobeam you will be using multiple channels at 5 Ghz 

all the ubiquiti equipment has the RF scan function so you can see what channels are in use before going live.  I keep a spare unit in my truck to use as a RF scan. 

With that many cameras I would forget about the Hik front end that is notoriously cranky with that much usage. Look into enterprise VMS that supports some type of data redundancy. Expect service calls with your wireless link 

I agree on the front end suggestion. It will be a pain to manage with Hik's non existing VMS.

About two years ago when i was working with Hik products we had multiple problems using encoders on the 128 ch Nvr's. On 2 specific sites after they had been installed for a couple of weeks the NVRs became unstable. Things like random reboots and NVR freezing would happen. We were unable to resolve this problem.

I would suggest following UM2 advice of stacking 32 channel Hik NVRs. There are many advantages. 

1. No single point of failure.

2. Can utilise hikvision hot spare mode to have a redundent NVR in the system. This is actually a great feature.

3. Higher overall incoming bandwidth. If i remember correctly the 128 channel Hik has 400Mbps incoming. 4 x 32 channel would have a combined incoming bandwidth of 800Mbps or more depending on the exact model.

4. Can Just use TVI recorders instead of encoders. It will do a better job and be cheaper. Last time i tried you could actually pull channels from  Hik TVI DVR into a Hik NVR over the network as if it was an encoder.

Only draw backs are additional rack space required and it is not as easy for the enduser to reveiw footage. You would most likely need to install software on a PC somewhere to give the enduser a good experience.

On my Comparisons the multiple 32 channels with TVI DVR setup was actually cheaper than doing 128ch with encoders. Not sure if it is still the case though.

Its about reliability , Try using a vms from another computer with client capability's , stand alone HV 32 channel recorders , access the cameras and recorders from Hv software and vms . 

allows redundancy, and  reliability. 

any failures are stand alone and can be traced easily. 

Still have one unit for access if needed. 

Not taxing the system with one pipeline all the time so it takes a load off the system. 

we have tried both and hv has issues when multiple cameras are accessed from multiple channels or access pts. vms clients at a time. 

had to dumb down the hv camera to get to work all the time with out issues. 

Other issue is if you are recording hv cameras from multiple pts or clients you have to make sure to balance the bandwidth loads (fps)

The surges create drop outs and camera failures , drop off line , had to reboot the camera each time. to fix . 

example: if hv allows 30 fps max and you are recording from or accessing with regular intervals , from 2 different sources , You must have both units recording at a lower fps and the same . Both at 15 fps. Not sure why , but it worked after we lowered the fps draw s out of the cameras and allowed them to be set for same number . and the camera set for variable output s and motion detection . 

When we did constant with no motion it taxed the system and lost cameras from the vms's ( 3 diff., 4 diff sources ) had to experiment due to remote systems , Not accessible thru internet 

or you have failures inconsistently

Took a while to figure out what the problem was . and how to fix.

 That is an incorrect assumption my friend. Yes the encoder will encode the 16 cameras

for you BUT it will not spit out 16 IP address as you may be looking for it spits out ONE IP address.
