does anyone make a high output multi port POE injector?

I have 4 cameras on one side of my driveway and 5 cameras on the other side with a netgear 8 port POE (GS108pp) switch on each side with their own home run to the main switch 230 feet away. one switch has a high output injector (Cudy POE400 90W Gigabit Ultra PoE++ Injector Adapter) powering a big hikvision speed dome. recently 2 cameras went off line so I pulled them down to test. they appeared be dead with no IP, till I hooked them up to another POE injector then they started working again. I bench tested them for a week with no problems so I am going to try and put the camera back using an injector and see what happens.

the other side has a brand new IPC-TPC124XB-AI-S2 1/2.7'' CMOS 4MP Thermal Network Mini Hybrid Bullet that worked for a week off the switch alone then suddenly died but as soon as I put in another POE injector it came back to life. both of the netgear switches with 130 watt POE are new. they are unmanaged so I don't think I can check the wattage to the camera on them. anyway if I have to keep adding injectors I have to put much larger ugly boxes on the columns at the gate so is there a good multi port POE injector?
 
In case you haven't done so already, I highly suggest register your 2 Netgear POE switches NOW to take advantage of their warranty, if they are "new" as you say.

Also, I would consider a high quality, properly chosen (based on camera power budgets) and applied POE switch to function as and take the place of a "multi port POE injector"......even more so since an 802.3af/at -compliant switch can furnish power in different modes depending on the device being powered. :cool:

where can I find the camera power requirements for each camera?

In the manufacturer's specs (PDF datasheet usually) for that camera.

For example, your IPC-TPC124XB-AI-S2, under "power" or "power consumption".

I think you are going to find that there are fewer and fewer multiport POE injector options as you move up the POE class. The 802.3bt (POE++) spec says that ports need to supply up to 90 watts of power (per port), so that would take a massive power supply for a multiport device.

POE Texas has some multiport POE++ injectors. I don't know anything about that company, but it is one of the few companies I found offering products. PoE Injectors

I've seen PoE Texas around for many years selling multi-port PoE injectors. They always looked legitimate to me, but I never bought anything from them because I never had a situation where it made sense to buy their multi-port injectors versus just getting a regular PoE+ switch or whatever.
 
I'd also spec with some headroom. Electronics don't like to be run at full tilt and it allows for the camera to draw more than stated under certain conditions.
