Digital / IP Security cameras
A digital network video surveillance system offers you a number of improvements over traditional Close Circuit Television (CCTV) video systems, like superior image quality and a large variety of built-in superior features such as scheduling, motion detection, multiple streams and more.
The major disadvantage and possibly deciding factor is cost. We will try and weigh the Advantages here over the traditional Analogue cameras.
Advantages
- High resolution and pixel perfect image quality
- Adjustable picture quality
- No electrical noise problems (electric spike and electronic interference)
- Adjustable quality with multiple streams for PC or real-time mobile viewing (through the Internet)
- Record footage to a PC, DVR or on to an onboard memory card
- Rich features such as
- scheduling
- controlling the Infra-red night vision
- motion detection
- multiple streams for PC and mobile viewing and digital recording
- Wireless IP cameras gives you the freedom to install the camera anywhere without complex wiring.
Disadvantages
- More expensive than analogue cameras
- A network is required for wired cameras (hub, routers or ADSL modem with various ports).
- The optional Power over Ethernet feature reduces the number of cables to the camera, but requires a POE hub or POE injector.
Video compression
To save storage space, bandwidth and to speed video delivery up, especially over the internet, compression is used.
The most popular compression used is H.264 and H.265
H.265 is much more expensive to license than H.264, even through the quality is much better and bandwidth is lower. For cameras, it makes little sense to move from H.254 when the price to license H.265 it much higher.
Some resourceful manufacturers use a modified H.264 codec called H.264 plus.
Some resourceful manufacturers use a modified H.264 codec called H.264 plus.
H.264+ (H.264plus) requires special equipment to connect to the camera. It is not standard but is an option on some camera brands. It saves bandwidth by 50% or more, especially on still frames.
ONVIF
ONVIF
ONVIF cameras are compatible across all ONVIF security video products, such as recorders. Purchasing an ONVIF camera will provide peace of mind that it is compatible with any ONVIF recorder you may get now and in the future, irrespective of the brand.
ONVIF is an open industry forum that provides and promotes standardized interfaces for effective interoperability of IP-based physical security products.
ONVIF (Open Network Video Interface Forum) is a global and open industry forum with the goal of facilitating the development and use of a global open standard for the interface of physical IP-based security products. ONVIF creates a standard for how IP products within video surveillance and other physical security areas can communicate with each other. ONVIF is an organization started in 2008 by Axis Communications, Bosch Security Systems and Sony.
It was officially incorporated as a non-profit, 501(c)6 Delaware corporation on November 25, 2008. ONVIF membership is open to manufacturers, software developers, consultants, system integrators, end users and other interest groups that wish to participate in the activities of ONVIF. The ONVIF specification aims to achieve interoperability between network video products regardless of manufacturer.

ONVIF membership is open to manufacturers, software developers, consultants, system integrators, end users and other interest groups that wish to participate in the activities of ONVIF. The ONVIF specification aims to achieve interoperability between network video products regardless of manufacturer.
The cornerstones of ONVIF are:
- Standardization of communication between network video devices
- Interoperability between network video products regardless of manufacturer
- Open to all companies and organizations
ONVIF specifications
- Interoperability – products from various manufacturers can be used in the same systems and "speak the same language"
- Flexibility – end-users and integrators are not locked within proprietary solutions based on technology choices of individual manufacturers.
- Future-proof – standards ensure that there are interoperable products on the market, no matter what happens to individual companies.
- Quality – when a product conforms to a standard, the market knows what to expect from that product.
The ONVIF Core Specification aims to standardize the network interface (on the network layer) of network video products. It defines a network video communication framework based on relevant IETF and Web Services standards including security and IP configuration requirements.
The following areas are covered by the Core Specification version 1.0:
- IP configuration
- Device discovery
- Device management
- Media configuration
- Real time viewing
- Event handling
- PTZ camera control
- Video analytics
- Security
Building on ONVIF specifications, ONVIF profiles are technical specifications that ensure the interoperability of specific features between conformant devices.

Camera lenses
F-Stop
f/2.0 = Smaller Aperture, Less light reaches Image Sensor, Deeper Depth of Field (More of the picture is in focus) than f/1.8
f/2.2 = Smaller Aperture, Less light reaches Image Sensor (poorer night vision), Deeper Depth of Field than f/2.0 (More of the picture is in focus - very sharp image across entire image)
Common problems with cameras and solutions
Spider webs and bugs in front of the camera
The IR usually attracts spiders and bugs to the camera. You can disable the IR and use an external IR.
You can use a "clean and kill" insecticide spray for the glass and an external environment insecticide on the case, but regular cleaning will be required.
Glass reflection
While mounting the camera indoors may seem like a good option, the window glass causes poor focus, and reflections. It is best to buy an outside camera and mount the camera outside.
Foggy / condensation
Fog and condensation can occur inside the camera.
Cameras may come with small packets of silica gel. Use these silica gel packets inside the camera to absorb moister. You can use silica gel packets from any other product inside the camera to keep the camera condensation-free.
Lightning damage
Lightning can damage the camera and recording equipment.
Ground your equipment and camera case very well, and use surge protectors and POE / Network surge protectors.

Outdoor cameras IP rating
Outdoor cameras have an ingress protection (IP) rating.
This IP rating is not to be confused with Internet Protocol Cameras, which are digital network cameras.
This rating is an indication of how well the enclosure will protect the internal space and electronics against the following:
This rating is an indication of how well the enclosure will protect the internal space and electronics against the following:
- Solid foreign objects of small sizes and dust
- Water drops, splashes, jets or submersion
The IP rating consists of two numbers (xy) and is indicated as follows: IPxy
The first digit (x) indicates foreign object and dust protection as follows:
- 0 No protection
- 1 foreign objects 50mm diameter or greater
- 2 foreign objects 12.5mm diameter or greater
- 3 foreign objects 2.5mm diameter or greater
- 4 foreign objects1 mm diameter or greater
- 5 Dust protected
- 6 Dust tight
The second digit (y) indicates water and moister protection as follows:
- 0 No protection against water
- 1 Vertical water drops falling
- 2 Vertical water drops falling when tilted at 15degrees
- 3 Water spray at an angle of up to 60degrees on either side
- 4 Water splashing from any direction
- 5 Water jets from any direction
- 6 Powerful water jets directed at the subject
- 7 Ingress of water when submerged in water under standard pressure and time (temporary immersion in water)
- 8 Ingress of water when submerged in water under longer periods of time (continuous immersion in water)
- 9 Water at high pressure and temperature from any direction
Example of protection for an IP camera:
- IP65, dust-tight and can tolerate water jets from any direction
- IP66, dust-tight and can tolerate high pressure water jets from any direction
- IP67, dust-tight and can be submerged in water temporarily
