Depending on the scenario of the installation (Length of cable and outside temperatures) you may notice that IR cameras using POE power connections will have a higher temperature when IR has been activated for long periods of time. This is normal due to the design of most POE switches and IP cameras. We discussed the report with the manufacturer of the POE switch and they confirmed and stated that the power supply design of POE switches do tend to consume more on most scenarios.
In this report you can see that measurements taken from an amp meter shows higher Watt consumptions using POE.
Measurements from Standard POE switch: 0.12 Amp/115V/ 13.80 Watts
Measurements from Same POE switch with 1 IP Camera:0.19 Amp115V21.85 Watts
Measurements from 12VDC Power Supply:0.08 Amp/115V/ 9.20 Watts
Measurements from basic 12VDC Power Supply with same IP Camera:0.12 Amp/115V/ 13.80 Watts
Below are the final mathematical calculations of this scenario:
Consumption of 1 IP Camera on POE switch:.07 Amps (0.19-0.12)115 V/8.05 Watts
Consumption of 1 IP Camera on 12VDC Power Supply:.04 Amps (0.12-0.08)/115V/ 4.6 Watts
Please use measurements as a comparison because IP cameras and Plug-in power supplies may vary by brand and model.

Important Things to Notice:
Both "Router #1" and "Router #2" have TWO IP addresses; an Internal IP address and an External IP address.
There are TWO LANs (Local Area Networks).
There are TWO WANs (Wide Area Networks). If there is a LAN then there is an accompanying WAN.
Now that we have identified these things we can go on to learn how they affect us.
Network Address Translation
For the sake of readability, from now on I will refer to "Router #1" and "Router #2" as "R1" and "R2" respectively.
Every router does NAT (Network Address Translation), and has both an internal IP address and an external IP address. The external IP address is the one that connects that router to the WAN (Wide Area Network). Usually the WAN is the Internet. The internal IP address connects the router to the internal network. Our network here is a bit more complex than the basic network.
R1's external IP address connects R1 to the Internet, just like any other network. R1 also has an internal IP address which provides NAT to the internal LAN1 network below it. The only thing connected to LAN1 is the router R2. R2 connects to LAN1 with an external IP address. Notice that R2's external IP address does not connect to the internet, but to another private network. Another way to say that is, R2's WAN IP address is external to R2 but internal to R1. R2 then provides NAT to the LAN2 network below it. R2 provides NAT through its internal IP address. The computers then connect to LAN2 and receive data from R2.
Let's assign IP addresses to everything, and see how it would look.
Notice that the IP addresses that exist on LAN1 differ from the IP addresses on LAN2. The IP addresses that are on LAN1 are 192.168.1.1 and 192.168.1.5. The IP addresses that are on LAN2 are 10.0.0.1 and 10.0.0.15. Here is another diagram to help show the network divisions:
Configure Port Forwards
Okay enough idle chatter. Let's talk about how to forward ports through this network.
[Step 1]
We want to forward ports from the WAN of R1 to a computer connected to LAN2. To do this we need to forward the ports in R1 to R2's external IP address. In this example we would log into R1 and forward ports to 192.168.1.5.
Note: In order to connect to R1's web interface one will probably have to plug a computer directly into R1 and establish a connection on LAN1.
[Step 2]
The next step is to forward ports from R2 to the proper network device whether it be a computer, XBOX, or PS3. (The Proper network device is the device on which you run the program for which you are forwarding ports.) In our example we would log into R2, and then forward ports to 10.0.0.15.
Static IP Addresses
You have now set up port forwards in your double router network and everything is working without a hitch. That's great, but if you have not configured static IP addresses for the network devices for which you have forwarded ports then your port forwarding settings are just waiting to break. When your port forward settings stop working, the most likely cause is that the network device for with you have forwarded ports has obtained a different internal IP address than the internal IP address that it had when you originally configured your port forward settings. The result is that your ports are no longer forwarded to the correct IP address.
How do I stop my port forward settings from breaking?
Static IP addresses allow you to assign an IP address to a network device and ensure that its IP address does not change.
The network devices for which ports are being forwarded need to have a static IP address. If a device does not have a static IP address, then it has a dynamic IP address. Dynamic IP addresses can/will change. As stated earlier, if the IP address of a network device for which ports you've forwarded ports changes, the ports will not be forwarded to the correct place. So it is important to setup a static IP address on the network devices for which you intend to forward ports.
The same applies to R2 in our example. R2's external IP address should really be static. This is not too big of a problem if R2 is the only network device connected to LAN1. If R2 is the only device on LAN1, it is unlikely that its IP address will change. If you have other devices on LAN1, you really need to setup a static IP address on R2. You would make configurations for a static IP address in the WAN section of R2

You want to program an Unidentified Developer on to your MAC BOOK
It should not have to be a huge task to do this so this document describes how to enable installation of applications from sources other than the MAC APP STORE on MAC OS.
Background :
By default, Mac OS 10.8 only allows users to install applications from 'verified sources.'In effect, this means that users are unable to install most applications downloaded from the internet or stored on physical media without receiving the error message below:
Users can follow the directions below to prevent this error message from appearing in one of two ways:
•Changing Gatekeeper's settings—this is useful for users who download a lot of programs that are not from 'verified sources.'
•Manually allowing individual applications to launch—this is the best method for users who do not want to change the global setting to allow all applications to run.
For more information about this message, please visit Apple's KB article on the topic: http://support.apple.com/kb/HT5290.
Change Gatekeeper Settings:
1.Open the System Preferences. This can be done by either clicking on the System Preferences icon in the Dock or by going to Apple Menu > System Preferences.
2.Open the Security & Privacy pane by clicking Security & Privacy.
3.Make sure that the General tab is selected. Click the icon Click the lock to make changes.
4.Enter your username and password into the prompt that appears and click Unlock.
5.Under the section labeled Allow applications downloaded from:, select Anywhere. On the prompt that appears, click Allow From Anywhere.
6.Exit System Preferences by clicking the red button in the upper left of the window. You should now be able to install applications downloaded from the internet.
To Manually Launch Application:
1.While holding down the control key on your keyboard, click the application's icon once to make a dropdown menu appear.
2.Select Open from the menu. A new window will appear.
3.Click Open in that window to launch the application. You should only need to do this once per application, on the first launch. After that, you'll be able to launch the application any way you like.

WHY?
Well because there may be a problem in the ROUTER. If the Router does not have the same WAN information to match our computer than there is a slight issue that you would have to contact your ISP (Internet Service Provider).
and have them correct it.

Q>If you ensure your IP-CAM is using multicast, you must replace the WNAP-6305 with the WNAP-7300 to prevent broadcast storm.
--> AVS IP cam & NVR Pro use omnicast
Q> He keep connecting FSD-804PS to another FSD-804 PS up to 10 in a row(it is called daisy chain connection). What is the maximum number of FSD-804PS he can daisy chain?
--> Max 10
Q>Betwenn WNAP-6305 and 7300 , which one is better for surveillance purpose?
-->For surveillance, it’s better to use 5GHz AP to prevent much interference from 2.4GH equipments. The WNAP-7300 is 300Mbps wireless AP, which has more wireless bandwidth than the WNAP-6305 150Mbps wireless AP.
Q>What is the data rate (bandwidth) of WNAP-6305& 7300 in real world?
WNAP-6305 @ 4Km : 48Mbps.
WNAP-7300 @ 5Km : 88Mbps.
Q>DATA RATE of WNAP-6305 is 150Mbit in the spec and channel bandwidth is 20/40 from below picture.
I saw 20/40 in the menu and thought maximum data rate is 40Mbit, which is totally wrong.
-> To reach the 802.11n’s max. wireless speed, you need to double the channel width from 20MHz (802.11bg) to 40MHz (802.11n), then it will be able to extend the theoretical data rate up to 150Mbps. The 40MHz channel width is proposed in the 802.11n's standard.
In the other word, a wider channel can allow more data packet pass through than the narrow channel, that why in the theory of 802.11n, we can get the wireless speed up to 150Mbps with the 1T1R's design.
You can refer to the wiki for the detail description of wifi channel: http://en.wikipedia.org/wiki/List_of_WLAN_channels
