How do you guys use this with IPcams which usually take 12V. This unit puts 48V through the cable... How/were is it regulated?

802.3af and 802.3at PoE devices have internal voltage regulators. They may require 12v when using a DC power adapter. But, if they're powered using a PoE switch or mid-span PoE injector, they recieve a higher voltage (usually 48v) on the Category cable, then step the voltage down internally to whatever is needed. 802.3xx PoE technology allows each device manufacturer to design their equipment as they need, simply taking the "bus" voltage then dropping it using an internal voltage regulator. The supply side of the circuit sends a constant voltage, independent of the component or its needs. 802.3af and 802.3at PoE devices have internal voltage regulators.

It is regulated. I think though you may have two things confused. A power supply DC fed camera does typically use 12v or 24v. The PoE standard (802.3af) is 48v. This is the same voltage used on phone lines. I don't know if that's a coincidence or not. Anyway, I have 2 of these PoE injectors and I'm using them to feed 3 IP cameras that use PoE and they work fine.

They sell models with different voltages. Keep searching WiFi-Soft LLC store. I see that they have 24V and 48V versions. Most cameras will regulate the voltage but to be sure verify with the camera mfg. Some POE cameras can take POE power AND 12VDC power. This gives you the option to use standard Ethernet and a separate 12VDC power supply.
1009236
any thing that says 802.3AF will be 48V, if it says POE you need to ask if its 802.3AF, if its not you need to know the voltage, most are 12 or 24 and some are 5, you can then you a power supply for the voltage you need for your camera, 802.3AF is an IEEE international standard

At the camera end you will need what is called a POE splitter. I have had good luck with the LevelOne POS-1002 PoE Splitter. You can get these on Amazon site as well.

The cameras I'm using are IEEE 802.3af Power over Ethernet 48vDC. Not sure if this is common or not. It's what I have.

Your IP cam needs to be able to handle multiple POE voltages. The poe injector does not do it by itself.

The label on the camera may say 12v / PoE. This means it uses 12 volt if powered from a local transformer, and 48v when powered via the Ethernet cable. Only Ubiquiti seems to use 24 volts via Ethernet cable for cameras. If the word PoE or 802.3af does not appear - then you need a splitter at the camera to extract the power from the ethernet cable for the camera, a passive splitter will work up to 75 ft, beyond that, you need an active splitter.

I have the 48V POE powering my Axis-M11 cameras - and all is well. The back of the camera states 44-57VDC. I think the POE spec states 44-57VDC.

1) Did you check to make sure you did not accidentally reverse the power/ground wires? 2) You said 18 channels - some cameras can consume a lot of power; Is your power supply adequately sized (plus some margin) to deliver power to all your cameras? To check this, I would unplug all cameras except for one. Then add in more cameras one by one. 3) Using a volt meter (and measuring resistance), did you check to make sure you do not accidentally have a short circuit somewhere? If your DVM shows 0, or something close to it, you might* have a short.

These do work with IP cameras although you have to be careful about how long your cable is. There will be a voltage drop over long distances.

The camera does not include the power supply, power adapter or the video/power cable. Both of my power supplies are for 4 cameras and have an input of 120-240v/1.5A and an output of 12v/2A, so presumably one camera could get by on a .5A supply like yours. See "Acelevel 60 Feet Video Power BNC RCA Cable for Q-See CCTV Security Cameras" for a clear picture of the ends needed for the power ends (red).

I had a similar need and decided to go with a different brand. The Q-See QS1018 12 Volt 12 AMP provides 1amp (default) or 2amp (they provide extra fuses) options per camera. Even so, I had 2 cameras that needed additional power due to IR counts and I was able to tie 2 power outputs together for 1 camera using homemade jumpers.

So you plug the master power into your standard outlet and insert the cat 5e cable from that power source into your router. Then pretty much do the same for the camera, plug its power source into a standard outlet and plug in the ethernet cord to that and then the other end goes into the camera. Its power over the ethernet cable. Just besure to not use any extension cords or surge protectors, as it messes up tge transmission. The instructions state bothpower sources have a surge protector in them. Definitely a DIY job, nothing fancy, very straightforward. All the best! Its a great unit!!

I use it on cameras that require 12V and it works just fine. No problems whatsoever! Definitely worth the purchase if you install multiple cameras.

Yes it uses 12VDC just like the other cameras. This particular camera has an extra connector for audio. The cord that comes with it has everything you need for this camera to work. You just connect the camera to your DVR system .

Don't know. It broke long before I explored any options. Just remembered. I have unswitched wiring in my cars (do it myself). So, the camera was always on 12V. But, I had to turn it on, before each trip.

Go to a Video service shop and they will run the cable for you. As for USB goes, you cannot.The video shop run my camera cable straight to the accessories fuse box, this way I don't need to use my 12V outlet.Also great camera.

I only bought the DVR. The cameras are generally 12V AC. This what I installed to this DVR. I personally would not buy the pictured cameras. They are overpriced for no reason. Good luck.

you have multiple options. One of which is start/stop recording based on the external power. The camera only takes 5v USB power, which comes from the plug converted from the 12V.

It uses a conventional DC power source used by most 12V security cams. Example - HQ-Cam CCTV Accessory-Power Adaptor 12V DC, 500mA ,UL Listed, Regulated, 110V AC

Hey Jennifer, you have to run a wire to that cam. You can use a batt but I would not recommend it. The proper way is to run a cable and a power wire. I hope this helps.

I believe the power supply is internal to the device, so it is very possible that it is 48v or higher.. I do know that you can set different ports to different voltages, I use it that way to power different kinds of devices. I have Access points and IP video cameras running off of this switch.

The camera has a pair of cables coming out the back. One is the BNC connector ending for video, the other is the power cable. The power is 12V, using the same sort of round power plug you'll see in many other small electronics before USB power was so common. In my setup I have these 100ft cables (came with the DVR I bought, but they are easy to find here on Amazon) that have a video line and a power line stuck together and two connectors on each end. The power side has a matching end that plugs into the power cable coming out of the back of the camera. On the far side I have an AC (Wall outlet) to 12V adapter that the other side of that cable plugs into. I have two of these, each has 4 plugs, so they run 4 cameras. Basically, you need: -The 12V wall adapter (with the right number of outputs for how many cameras you have) -Cables (Video+Power BNC and the correct power plug, and the right number of them) -DVR -Camera itself

The 12v input line is not regulated, thus it is limited by the power supply feeding the picopsu. I've used this in a number of setups that draw 20+ amps on the 12v line without a single problem years later. Now as for the 5v and 3.3v rails, that is another story.
