KNOW BEFORE YOU GO
Does Customer have Broadband
– Is Broadband Cable or DSL
• If Cable it is likely that ISP provides a router most often
it is a wireless router. It is likely that the router
authenticates with ISP based upon its MAC address so
changing router may cause customer to lose ability to
connect to internet.
• Make sure customer has username and password
information to log into router. Often found on a sticker
on side of device.
KNOW BEFORE YOU GO (2)
If DSL does customer know PPoE authentication
information. ( From ISP and cannot be guessed)
– DSL often provides a Modem/Router where device
only has a single RJ-45 port.
– If Customer has login information for
Modem/Router user can add a switch.
– IF ISP does not allow user configuration of device
than device must be put into “Bridge” mode and a
second router must be added so configuration can
take place.
KNOW BEFORE YOU GO (3)
In case of DSL and Cable there must be an
open port for NVR/DVR/Camera to connect.
• YOU MUST have a PC with you to configure
router. This CANNOT be done via the
DVR/NVR.
• You must have enough Ethernet cables to
connect Devices simultaneously.
KNOW BEFORE YOU GO (4)
• Know in advance how many ports need to be
forwarded.
– Some Devices only require one port such as the
http port. Other devices require http and media
port. Others can require http, media/rtsp and
server ports.
– Know if ports can be changed on CCTV device or if
they are fixed.
– Know if Router supports External/Public ports to
be different from Internal/Private ports
Understand Basics Of Computer Addressing and Subnets
• TCP/IPv4 are still most common used.
– All address have been allocated but because of
heavy use of private subnets most ISPs are still
providing a v4 address.
• TCP/IPv6 provides enough address for every
star in the universe to have 100 address.
• Understand difference between a Public and
Private address.
Understand Basics Of Computer Addressing and Subnets (2)
• Private address such as 192.xxx.xxx.xxx or
10.xxx.xxx.xxx can only be seen by devices
who are part of the same network. Address of
this type can only be seen when user is part of
INTRAnet or LAN.
• Public address such as 68.88.xxx.xxx can be
seen from anywhere in the World (thus the
term World Wide Web) and are part of
INTERnet or WAN.
Understand Basics Of Computer Addressing and Subnets (3)
If Your IP camera has the IP address of 192.0.0.64
and you computer has the address of
192.168.1.101 you are not going to be able to
view a live image.
• Likewise if your DVR is plugged into the router
and has the address of 192.168.1.50 and your
laptop is connected via a wireless connection and
has the address of 192.168.2.100 you cannot see
the images from the DVR. It is not uncommon for
the wireless subnet to be different than the
wired.
DETERMINE IP ADDRESS OF COMPUTER
• With Command Box open type command
“IPCONFIG” which stands for IP configuration.
Fastest way is by using “Command Prompt”
– Windows XP go to START, click “run” type cmd or
command and press enter
– Widows 7/8 type “Command Prompt” into search
window
DETERMINE IP ADDRESS OF COMPUTER (2)
• Note that it shows that the wired Ethernet
connection shows “Media Disconnect”
– If you are using a wired connection and this
message is displayed check cable
– This message may also result if you are plugged
into a switch and no router is available
– If possible always use a wired Ethernet connection
as wireless can add variables (like a different IP
subnet than the wired connections) that must be
accounted for when troubleshooting
DETERMINE IP ADDRESS OF COMPUTER (3)
• Wireless connection shows TCP/IPv4 address of:
192.169.1.102 with a default gateway of
192.168.1.1
• Subnet mask will be 255.255.255.0 in 99% of the
cases when IP address is 192.xxx.xxx.xxx as it is
standard subnet mask for this subnet (Class C
type)
• The Gateway address is the address of the router
where the port forwarding must take place.
Warning!
• For port forward to work you must be using
router that is connected to the World Wide Web.
• Look for the WAN/Internet/Public address of
router and make sure it is not an 192.xxx.xxx.xxx
or 10.xxx.xxx.xxx address. If it has one of these
private address for its Internet address there is
another device on site doing the routing. You
may therefore need to forward the desired ports
in one router to the IP address of the second
router to which the CCTV device is connected and
then again in that router to the CCTV device.
Warning!
Configure Router (1)
• Open Browser (ie works more times than not
though you can use Google/Firefox etc.)
• In URL bar type http:// and the gateway
address. (in example it is 192.168.1.1)
Configure Router
• Most of the time a “challenge screen” will appear
requiring you to enter user name and password.
Some AT&T routers do not ask for username and
password until an attempt is made to make a change.
Configure Router (2)
• Where you go next can vary greatly. Some routers put port
forwarding under “Applications and Gaming”. Others under
Advanced Options/Pin Holes or Advanced Options/Port
Forwarding. Refer to Router user Manual
Configure Router (3)
• This shows using external (Public) ports that are different than
the Internal (Private) Port. User on local network does not
need to put :8008 at end of IP address in previous slide.
Configure Router (4)
• Some Routers have security features which will prevent
viewing of video from outside network. Linksys/Cisco for
instance require this change within Security Settings
Configure Router (5)
• The CCTV device to which you are forwarding
needs to have a static address. You cannot have
DHCP enabled on device.
• DHCP (Dynamic Host Communications Protocol)
means the device is “set to obtain IP address
automatically (computers are set this way by
default).
• Which address is assign to which device is
dependent which device boots faster. It is very
likely that device will a different address causing
ports to be forwarded to wrong device.
Trouble Shooting
• If you can connect to the DVR/NVR/IP Camera
across the network but do not get video than
one of the ports may not be forwarded
correctly.
• It may be necessary to reboot the device in
order for network changes (like changing the
RTSP port) to take affect
Trouble Shooting (2)
• If device can be seen locally but not remotely
port may be block by ISP or Cellular provider.
AT&T for instance frequently blocks ports
below 1000 and in some areas below 2000.
Making the RTSP port and HTTP port higher
than 2000 may resolve problem.
• Forwarding a port does not “open” that port
for remote viewing if ISP or Cellular company
blocks it on their side.
Verify Success
• To see if the port forward is successful attempt
to use the public address to see the CCTV
device.
– Sites such as www.canyouseeme.org
– www.whatismyip.com
– www.speedtest.net
– www.portforward.com
display the public address being broadcast.
Verify Success
• Sites like Can You See me Can also help test if
port is visible to outside world.
CONGRATULATIONS YOU HAVE DONE IT!!
• Remember if you are using WiFi at the site you
need to use the LAN or local address
• If your phone is on 3/4G you can view using the
Public address
• Call someone away from the site and have them
attempt to log in.
• Set up two log ins on customers phone one for
local and one for away.
• Remember that if http port other than 80 is
forwarded it must be tacked onto the end of the
public address: 76.11.151.30:8000
QUESTIONS?
• Do not waste time setting up a port forward it
should take 10 minutes or less if all information is
known.
• Consider paying an IT specialist if you are unsure
of situation
• Consider using a third party port forwarding
configuration software. (Portforward.com has
some manufactures integrated and for $30 they
will do it for you. HikVision is integrated).
• When in doubt, Reach out!
ADDITIONAL INFORMATION DDNS
• DDNS stands for Dynamic Domain Name
Service.
– For 99% of home owners and 80+% of businesses
the Public IP address they have is Dynamic, not
static, and changes on a regular basis. How long
you keep an Public address is know as the “lease
period” The length of the lease can usually be
obtained from the ISP. Some leases can be a few
hours long and others may last until such time as
the equipment is powered cycled even if that is
months.
ADDITIONAL INFORMATION DDNS (2)
• Many routers support services that will allow
a user to create a name that will be associated
with a changing Public IP address. Most (DLink
has their own server) use third part
servers such as No-IP.com or DYNDNS.org
which require users to go to those sites and
create user accounts which are then added to
the router configuration.
ADDITIONAL INFORMATION DDNS (3)
This router supports DynDNS.org which is free and TZO.com which cost ~$30/ year
Free is nice but since no one is making money uptime is not guaranteed.
ADDITIONAL INFORMATION DDNS (4)
Many CCTV manufactures have their own DDNS servers. Large companies like
HikVision usually have better uptime records than those that rely upon others.
ADDITIONAL INFORMATION DDNS (4)
• Create an account that is easy to remember
• Know correct path to find the server you
created like Hik-online.com/mydvr
• The username and password is information
used to create DDNS account is not the same
user name used to log into DVR Menu.
• Each IP camera can have a separate DDNS
account.
