HD
Analog CCTV vs. IP Video Surveillance
IP cameras (commonly referred to as Network
cameras, or Megapixel cameras) feature an embedded video server that converts
images into a digital format inside of the camera. Because IP cameras are
embedded devices and do not need to output an analog signal, they are capable
of capturing far higher resolutions than traditional analog cameras.
IP cameras connect to a local network via a
single Ethernet cable, which transmits power, video and data to and from the
camera. Additionally, IP cameras have a unique IP address, and can be accessed
directly via the network – providing remote access and storage flexibility.
Without question, the primary benefits of IP
security cameras are resolution and image quality – allowing users to capture
forensic level detail, and to digitally zoom in on any image without losing
clarity. This results in more effective identification, and provides greater
accuracy for automated analysis, alarms and notifications.
Most common IP solutions range from 1.3
megapixel (1280 x 1024 pixels) to 5.0 megapixel (2592 x 1944 pixels), and some
manufacturers offer IP cameras that deliver 20+ megapixel resolutions. However,
the resolution and frame rate captured for a specific application are typically
limited by storage and bandwidth constraints, and higher megapixel models can
be cost prohibitive.
IP video surveillance solutions have
experienced a dramatic increase in popularity, driven by the capability to
capture higher-resolution megapixel video, an overall increase in adaption and
understanding of IP-based technologies, simplification and increasing
compatibility of IP security technology, and reductions in cost as demand (and
production volume) continues to grow.
Benefits of IP
·
Capable of higher
resolutions than traditional analog solutions
·
Transmit power, video
and data over single Ethernet cable
·
IP camera can operate
as a standalone network device, capable of functioning without a network video
recorder
Limitations of IP
·
Require a complex
network technical knowledge technical person to implements the system. Cannot
do any one. Need excellent infrastructure
·
Offer limited
transmission distance
·
Commonly experience
video latency in some situation
·
Require considerable
network bandwidth since ultra HD video data transmission.
·
Can be costly compared
to traditional analog and comparable Analog HD systems

The Advantages of HD Analog
HD Analog systems are capable of delivering up to 1080p HD video
– addressing the primary shortcoming of traditional analog solutions. 1080p (or
2.1 megapixel) cameras capture more than 4x the resolution of the most powerful
analog cameras – allowing users to effectively zoom in to view the level of
detail required for most common security applications.
Additionally, HD analog systems are capable of transmitting
video over standard coaxial cabling (new or existing) – dramatically reducing
the time, cost and complexity associated with a comparable IP solution. HD
cameras can transmit video up to 1600’ – over 5x the distance of an IP system,
and transmits with zero latency – a very common issue with most IP
installations.
HD Analog systems are as simple to install and maintain as
traditional analog solutions – not requiring the networking equipment and
knowledge associated with IP solutions. And because HD Analog lives off the
network, they don’t interfere with other network-related activities, or consume
valuable network bandwidth required by other devices.
There are no licensing or recurring fees associated with HD
Analog solutions, and all channels come completely enabled – for the life of
your product. Comparable IP solutions commonly require the purchase of a
license for every channel used, and a recurring annual fee to maintain that
license. This is an important consideration from a perspective of both
management complexity and total cost of ownership.
And importantly, HD technology has become increasingly
accessible. With the growing demand for higher definition video and the recent
emergence of more cost-effective technologies, the market price for HD Analog
solutions has reduced dramatically – almost to Analog levels. HD Analog
equipment is now available for less than half the price of a comparable IP
solution.
