TV lines are the number of horizontal lines that are in the image.
The more lines that are in the image the better the quality of the image.
A camera that has 700 TVL will have a clearer image then a camera that has 420 TVL.
CCTV resolution is calculated in vertical and horizontal pixel proportions and in
general, is limited by the capabilities of both the camera and the recorder that are
part of your CCTV surveillance system. For television specifications (which CCTV uses)
D1 resolution is the maximum resolution that can be captured and stored on high-end CCTV DVRs
(digital video recorders). D1 resolution is 720 x 576 pixels (PAL).
The lens size determines how large the image is, and how wide the field of view is for the camera.
The smaller the lens size, the smaller the image, but the wider the field of view.
The larger the lens size, the larger the image and the smaller the field of view. You would
use a camera with a smaller lens when you want to cover a large area such as a backyard or a
wall of merchandise. You would use a larger lens to cover a walkway up to a door when you need
to identify someone sooner, or to cover a register area where you need to see the transactions.
Varifocal lenses offer more flexibility, allowing the field of view to be adjusted manually,
so you can have a higher resolution image capture of a smaller area.
This is great if you are mounting the camera high up under an eave, or if you wish to narrow
the angle to fix on a door or pathway.
To configure motion detection:
First, go the DVR menu and click on 'Advanced', here the will find the Motion Detection (or MD) icon,
please click and enter this settings menu.
1) Under STATUS, select ON to enable motion detection for the desired channel.
Click NEXT PAGE for additional channels (8-channel models only).
2) Under SENSITIVITY, select 1, 2, 3, or 4.
The higher the number, the more sensitive the motion detection.
3) Under MD SETUP, click SETUP.
The red motion grid appears over the selected channel in full screen.
4) Click the blocks in the grid to enable/disable motion detection.
Red = motion detection enabled.
Clear/White = motion detection disabled.
5) Right-click anywhere on the screen to return to the Motion Detection menu.
6) Click APPLY. Click CLOSE in the confirmation window.
7) Click EXIT in all menus until all windows are closed.
01. You can disable the Motion Detection buzzer in the Alarm Setup menu.
02. The channel/Camera you wish to use Motion Detection on
must also be set to alarm in the schedule, otherwise that channel/Camera will
continually record by default.
Dynamic IP addresses constantly change, different addresses are sporadically allocated.
Static IP addresses are fixed and always stay the same..
Pan Tilt and Zoom cameras (PTZ) are specialised cameras which can rotate 360 degrees, zoom in and
out and move up and down. They can be controlled through the DVRs interface or via a dedicated controller
such as a 3D Controller Keyboard. Accessibility and control of the PTZ camera can also be
achieved via an internet enabled DVR, allowing for the cameras manipulation over the Internet.
RS-485 (a 2 wire connection) is the standard used for data transfer involving PTZ cameras, and as many
PTZ cameras can be connected to the DVR as its channels dictate.
First you will need to connect the DVR to a router via a network cable.
You will also need to have a computer connected to the same router,
preferably via a network cable, however wirelessly is OK for this purpose.
01. Identifying Your Computer Network
First you will need to find your LAN (local area network) details.
If however you already know these you can skip this part.
Alternatively if you are using another operating system such as Apple or Linux,
then please use their method for obtaining this information.
To identify the network settings, please follow the steps below:
Click the 'Start' or Windows button first.
A) Select Run (Windows XP only, skip this step for Vista/7)
B) Type in 'cmd' and press the < ENTER > key on your keyboard.
C) Type in 'ipconfig' and press the < ENTER > key on your keyboard.
D) You will need the 3 addresses below to use later so make a note of them.
02. Assigning an IP Address to the DVR
In the network setting of your DVR you will need to enter 2 of the addresses you collected
in the previous section.
However first it is advised to set the DVR to DHCP, so that the router locates and
automatically assigns an IP address to the DVR. After you have applied/saved this
setting you should exit the settings menu, at which point the DVR may reboot/cycle.
Once the DVR has completed a reboot/cycle you should revisit the DVRs network settings.
The 'Subnet Mask' and 'Default Gateway' addresses should now match those that you noted
If this is the case you are half way there so well done!
You should now make a note of the IP address that the DVR was assign, as this is the
address you will use to connect to it locally via Browsers and the CMS software.
* If however the details that were given to the DVR from the router whilst in DHCP mode,
did not match those previously notes then please continue with the section below.
Now you must switch from DHCP mode to Static, sometimes this option is not available so
just deactivate DHCP if this is the case. If the IP Address, Subnet Mask and Default
Gateway all stayed the same then simply save/apply and exit as this part is now complete.
If the addresses did change then you must manually enter them using the information you
noted. Again save/apply and exit for the change the take effect.
You should now be able to connect over your Local Area Network via Browsers or the
When motion detection is triggered, the system will extract a picture at
the time of triggering and send it to the corresponding mailbox.
