This post will walk you through setting up a CCTV DVR for remote viewing on Mobile or PC.
Connect the cameras to your DVR using BNC connectors & provide the power supply to DVR.Connect a mouse to the USB port.To view the cameras the DVR can be connected to a monitor through the VGA output of DVR or to a TV through the Video out pin (you may need a BNC to RCA converter)
Connect the DVR to the Network Router (providing internet connection as well as LAN) using the RJ45 Ethernet cable.
For this demo I’m using BUSH PLUS DVR H-264 Model 9308 & a Linksys Router.
Right click on DVR screen to get the Menu list.
Click on Home & then click on Network tab.
For Net Link there are two options . Static IP & DHCP.
If you select Static IP ,you’ve to feed the IP address manually.
DHCP is Dynamic Host Configuration Protocol.Generally a Router is at the top of a Network & it assigns IP address to a device like DVR when connected to it.
Select this option DHCP.
Note down the IP Addresses.
Here the IP address of DVR is assigned as 192.168.1.108 & the Gateway address is 192.168.1.1 .
The Gateway address is the IP address of the Router.
To view DVR over Internet or Mobile you’ve to open two ports for the incoming traffic on your Router.
1) HTTP PORT &
2) MOBILE PORT.
At the bottom you can see HTTP port assigned as 80.This is the default port for webservice WWW.
Click on the arrow mark next to Netservice to know the Mobile port number.
Here the Mobile port number is shown as Mobile Monitor & port assigned is 34599
Now we shall see how to open these two ports 80 (HTTP) & 34599 (Mobile) inside Router’s settings.
This process is called Port Forwarding.
PORT FORWARDING SETUP ON ROUTER.
Open a web browser like Internet Explorer or Firefox.Type in the Gateway IP address 192.168.1.1
Following table is a list of some Routers with IP address ,Username & password.
In this demo we’re using a LinkSys Router. So type in the IP 192.168.1.1
User Name is admin & password is also admin
Setup Window of Router opens.
You can note that the Router IP address as well as Network IP address are displayed.
Click on Application & Gaming tab.
Click on Port Range Forwarding tab.
Enter any name under application , say , DVR . Under start , as well as End enter the HTTP port 80.
Select Protocol as Both. Under IP address enter the IP of DVR. Here it is 192.168.1.108.
Check mark the Enable.
Same way enter application name as DVR1 for the Mobile port enabling. Under Start & End enter 34599 .Protocol is Both & IP is the address of DVR.
Save the settings.
Now it’s time to check whether the Forwarded Ports can be seen from outside over Internet.
This website displays your current external IP address , along with a question “What Port ?”
Enter the HTTP port 80 & click on Check port button.
You should see a “Success : I can see your service on IP xxx.xxx.x.x on port 80 “.
Again check for the mobile port 34599 to see a success.
If you do not get a success , the port forwarding you’ve done is not correct.Again open the Router Setup & check the correct entries for port forwarding.Check whether the Enable box is checked.
Once you see Success on this site , you can go ahead with your Mobile installation.
For Windows 8 Mobiles install from the store an application called MEYEPRO
Under Devices feed in the device info like IP address ,Mobile port number (34599) , User Name of DVR (admin) & its password (blank).
Once you enter the correct details, you can view your cameras connected to DVR over the Windows Mobile.e
For ANDROID phones install VMEYEPRO
Enter the Device info as we did for the Windows phone for a mobile view of DVR.
Please note that here I’ve used Dynamic IP address ,which changes every time the router is switched off & On again.To get a Static IP address which is fixed & do not change , contact your Internet Service Provider & get the address for a monthly rent.
There is also another option.Get a DYNDNS account (which is also not free now,yearly $25).This account will keep track of your Dynamic address & provide you a static one.

How to view your CCTV DVR on Mobile
For availability of BUSH PLUS range of CCTV cameras & DVR s contact :
First thing you have to note is the Image Sensor of the camera(which is responsible for transforming light into electrical signals). 2 types are available in the market :
a) CMOS type (Complimentary Metal Oxide Semiconductor)
b) CCD type (Charged Couple Device)
CCD sensors are costlier compared to the CMOS counterpart.Image quality from a CCD sensor is far better than that from a CMOS.
CMOS cameras of image sensor size 1/4” are widely used commercially.Even though their image quality is limited ,they are very much cheaper & it is possible to produce smaller size cameras.They also consume little power.
CCD cameras with image sensor size 1/3” are available in the market with either Sony chip or Sharp chip.The quality of image produced by these cameras are superior .
You may make a note that the image sensor in a common mobile phone camera or a webcam is of size 1/6”.
So 1/3” is superior to 1/4” or 1/6”.
2.RESOLUTION
Next thing to consider is the Resolution of the camera which is defined by the number of horizontal TV lines (TVL).A normal television image is produced from 625 TVL.Todays LCDs are digitized & the picture is made up of pixels & not TVLs.The more pixel you have the better the image.
A camera capable of 300 to 400 TVL is a Low resolution camera. 400 to 500 TVL is Medium resolution.Above 500 TVL is high resolution.
A 1/3 ” Sony CCD camera has normally 420 TVL and that of a Cmos camera is 380 TVL.
Night vision cameras fitted with IR LEDs are also available,which is suitable for places with less lighting.
3. FPS Frames Per Second
Another feature to look into is the FPS of the camera.
A still photo is nothing but capturing a moment at a time,and a motion picture is capturing an extended moment of time.i.e., a video is a collection of pictures or frames taken at a given rate.You get an impression of motion video,when you see the pictures taken in rapid succession.
If the FPS of a camera is lower,then you see jerky picture or a picture with hiccups.DVD movies you see generally take 30 fps,which is the maximum frame rate possible.A human eye can register up to 30 fps only.
A camera with as low as 15 fps still can show you a good quality video.The smoothness of video suffers when fps is below 10.
A camera with Sony CCD of image sensor 1/3” , resolution 420 TVL & 20 FPS is considered the best quality camera with highest value for money.
DVR
A DVR is a digital video recorder (DVR) that records motion video in a digital format to a hard disk. This can include various models such as stand-alone, USB DVR ,capture board plugged inside PC. . Software enables personal computers to extract segments of video for playback from the hard disk.
Before making a choice of CCTV DVRs you need to look into some important details such as the resolution and quality that you want, the recording options, footage accessibility, audio recording options,ability to view footage on mobile phones,ability to be monitored over internet,capacity of Hard disk supported,types of output supported VGA/RCA,motion detection recording,etc..
Basic two types of DVRs:
Stand Alone DVRs (does not require a PC)
DVR Cards (require a PC)
DVR capture boards are available and are simplest to install in the PCI slot of your existing Desktop computer.A standalone DVR is like a set-top box with elegance & style.USB DVRs are also available,but not preferred because of poor resolution recording and no smoothness or real time recording.
DVR Digital Video Recorder receives the analog signals from the cameras and convert them to Digital (LCD monitors do the same function).So a DVR is going to limit the resolution of the recorded video to certain extent.
Even if a camera is capable of delivering more than 540 TVL of resolution, the DVR IS NOT GOING TO RECORD AT THE RATE ABOVE 540 TVL. So a camera with resolution more than 540 TVL is really not going to benefit the user.
