This document provides an overview of IP camera systems compared to analog systems. It discusses the differences in connections, image quality, and recorders between the two types. It then describes the various camera choices available, including bullet, dome, and covert cameras. Recorder options that support different numbers of cameras and resolutions are presented. An example setup is shown along with a wiring diagram. Additional equipment like switches, injectors, and cables are discussed. Things for buyers to know about IP systems like network configuration are covered. The conclusion states that IP camera systems provide superior image quality and will eventually replace analog systems.

3. What are the main differences
between an IP and Analogue system?
There are several major differences between IP and Analogue CCTV setups. In this slide we will look at a few of these
main differences.
1. Connection type; IP cameras use RJ45 connections and CAT 5/6 network cable, whereas an analogue system
would use BNC connections with RG59 cable. The key difference here is that the analogue system all wires back
to the DVR, the cameras must have a direct connection to the DVR. With an IP system, because it is using
network cable it doesn’t need a direct connection to a recorder. You could for example have all the cameras
wired into a network switch in the loft and have that connected to your home network. This gives you a lot
more flexibility in terms of setup.
2. The second major difference is the image quality. An analogue system is measured in TV lines and is not High
Definition or HD. IP cameras are digital and are HD, either 720p and 1080p. This means that IP cameras offer far
superior image quality.
3. The final difference is the recorder, with an analogue system you would use a Digital Video Recorder (DVR) but
with an IP system you would use a Network Video Recorder (NVR) The differences are minor but the key thing is
that the cameras do not need to be directly connected to the recorder, because the NVR can access your home
network the cameras could be plugged in anywhere.
4. What Camera choices are available?
Bullet Camera: Dome/Eyeball Camera:
We offer IP Cameras in 3 different forms; bullet, dome and covert/camouflage. Our bullet cameras come in 720p or
1080p variants, have 30m infrared night vision and vari-focal lenses. Our dome cameras come in 720p and 1080p
forms with wired or WiFi connections, they have fixed lenses and 15m night vision. Our camouflage cameras come as
a smoke detector or PIR sensor.
Camouflage Camera:
5. What Recorder options are there?
The main difference between the NVR’s are the number of cameras they can record and at what resolution. Here is a
table showing our 3 NVR’s and what resolution they can record at.
NVR Model 4 Cameras Res. 8 Camera Res. 16 Camera Res. 24 Camera Res.
4NVR 1080p D1 Resolution X X
8NVR 1080p 1080p 720p X
24NVR 1080p 1080p 1080p 1080p
6. Example Setup
In this example setup we are going to use a PoE (power over Ethernet) camera, a locally powered camera and
a camera powered using an injector.
To use a PoE camera you would need a PoE switch, these are quite expensive, we offer injectors as a solution
to this problem. The wiring diagram on the next slide will show you how everything wires together. The PoE
camera would have a Cat5/6 cable running straight back to the PoE switch, this cable would power the
camera and run the data feed. The locally powered camera would be connected to a mains power supply and
then send the data feed back to the switch, again via a Cat5/6 cable. The camera using the injector is basically
the same as the PoE camera except that there is a separate power supply at the switch. This means you can
run power and data down a single Cat5/6 cable without the need of a PoE switch. This is a cost effective way
of running less cables around your building.
Once you have all your cameras connected to the switch, you can see that there are 2 more network cables
running from the switch to your router and the NVR. The NVR could be connected directly to the switch or
connected to your router, this would depend on how you are setting things up. We would recommend having
the NVR connected to the switch and not the router, though sometimes this isn’t possible. Your router would
provide access to the internet and allow mobile access.
8. IP System Extras
We offer lots of an additional bits of kit to get your IP system setup perfectly.
We sell 5,8,16 and 24 port switches, allowing you to connect all your cameras up.
We also sell Injectors, these allow you to send power down the Cat 5/6 cable. This means you only have to run one
cable to your cameras. Injectors are a great and cheap way of effectively making your Camera Power over Ethernet
(PoE) normally PoE setups are a lot more expensive but with our little injectors you can do it a lot cheaper and a lot
more reliably!
Finally we have all different lengths of Cat 5/6 cable, pre-cut at 5m, 10m, 20m, 30m, 40m or 50m lengths or
100m/305m uncut drums with connector packs. Whatever the cable requirement, we have it!
9. Things you need to know before you
consider an IP System
An IP camera system can potentially be quite complicated. Our
support team are here to help you if you run into difficulties but
there are few things you should probably know about before you
buy.
Here are a few simple questions, if you can answer these then an IP
system would be fine for you:
Would you know how to find out the IP range of your network and
set a device IP address to one that would work on your network?
Do you understand how to log into your router?
Do you understand port forwarding?
10. Conclusion
High definition IP camera systems are definitely the future of CCTV.
The image quality is so far ahead of analogue systems that this is
inevitable. Right now we offer a relatively small range of cameras,
but as the technology improves we will be able to offer far more
choice. Eventually we will only sell IP systems, just like analogue
television systems the old technology will fade away and be
replaced by the new higher quality systems.
