The first choice in a video surveillance system is to decide which types of cameras are right for your system. Should the cameras be analog or digital (IP)? The right choice depends on many factors. Let’s take a look at some of the advantages and disadvantages of each:
Analog vs. IP cameras: Analog cameras provide a simple BNC or UTP (CAT3+) video output which can be viewed on a monitor. IP cameras include an onboard encoder and web server which allows the camera to function as another device on the network.
Pros of Analog Cameras
- Lower cost – Without all of the built in options, intelligence, encoder, web server, etc., analog cameras generally are much cheaper
- Greater variety of cameras – Having been around for decades, there are a wide variety of camera designs available, from various mini covert cameras to a wide variety of sophisticated PTZ cameras. There is also more analog hardware available for custom applications.
- Compatibility – Analog is analog and a wide variety of cameras can exist within the same system.
- Familiarity – Owners and integrators and more familiar with analog cameras and the marketplace is flooded with analog equipment
- Flexibility – Any analog camera can be made into an IP camera with a video server
- Reliability – Standalone system that does not rely on network or internet where IP cameras can be affected.
Cons of Analog Cameras
- Lack of features – Analog cameras (except at the highest price points) lack many features that IP cameras offer, such as digital zoom.
- Wireless interference – Wireless transmission with analog cameras is unencrypted and can have more problems with interference.
- Long distances more difficult – The infrastructure required for a long distance analog camera can be difficult and expensive, and wireless is not secure.
Pros of IP Cameras
- Use of existing infrastructure – Utilizing a CAT5 network infrastructure that is already in place can save on installation time and costs.
- Remote access – IP cameras have more options for remote access than analog and can be accessed remotely with a DVR onsite.
- Better suited for wireless – IP cameras have encryption built in (digital wireless standards), and interference is rare.
- Intelligence – IP cameras have more intelligence built into the camera itself as opposed to the DVR. This provides the capability to operate as a standalone device and reduces workload on servers and processors.
- Hybrids – Some IP cameras offer network ports as well as a secondary analog port for use in systems that are not ready to convert to IP but may in the future.
- Higher Resolutions – IP cameras can achieve much higher resolutions than analog.
- Less cabling required – IP cameras can utilize POE standards for power and PTZ controls can utilize the same cable as well.
- Image quality – Progressive scanning (vs. interlaced scanning for analog cameras) provides a much clearer image especially during motion. *Not all IP cameras are using progressive scanning…
Cons of IP Cameras
- Higher cost – With all of the additional feature usually built into each camera, the cost can be much higher than analog, however the cost should continue to decrease.
- Network load – Higher bandwidth is required due to the higher resolutions and amount of information carried in the video signal. Depending on the size of the system, this can use a large portion of the available bandwidth in a network, and a separate network may need to be installed specifically for surveillance.
- Low light settings – IP cameras currently do not handle low lighting situations as well as good analog cameras.
- Lack of standards – Analog cameras are standardized on PAL and NTSC depending on your location. IP cameras can transmit video in a variety of ways, thus different manufacturer’s equipment and cameras will not always function together.
- Down time – If network or internet is down between locations, you will not have streaming or recording video. Contingency plans should be in place for backup recording.
The next question to answer is what type of video storage you would like to have. This will, of course, depend on the type of cameras installed. There are a wide variety of digital video recorders (DVR’s) and network video recorders (NVR’s) to choose from. DVR’s must be located in a central location for all cameras to cable back to, whereas NVR’s can reside anywhere on the network that the cameras are attached to. There are many factors when it comes to disk storage calculations for video storage.
