Fixed Box Camera

Fixed Box Camera

Fixed Box camera is, with the exception of the pin hole camera, a camera in its simplest form. The classic box camera is shaped more or less like a box, hence the name. A box camera has a simple optical system, often only in the form of a simple meniscus lens. It usually lacks a focusing system (fixed-focus) as well as control of aperture and shutter speeds. This makes it suitable for daylight photography only. In the 1950s, box cameras with photographic flash were introduced, allowing indoor photos.

You can choose fixed cameras with:

A fixed camera is the best choice when a traditional camera design is preferred for deterrence. The viewing direction is set once the camera is mounted. There are several models with a varifocal lens and/or exchangeable lenses for increased flexibility.

Housings are also available for mounting the camera outdoors or in harsh environments.

Static Dome Camera

Static Dome Camera

Static domes are often vandal resistant and used for short-range with wide angle view surveillance purposes. Because the unit is fixed, the low light issues involved are similar to those of other standard cameras. In low light or zero lux conditions, fixed domes will require additional lighting. Typically, IR lighting provides the best, most practical and cost-effective solution.

If you are looking for a Static dome camera – sometimes referred to as “mini-dome” .You will even find some of the most compact and discreet fixed dome cameras on the market, measuring only 10 cm / 4" in diameter and 4 cm / 1.5" high.

There are several fixed dome models to choose from, including cameras that offer:

A fixed dome camera is a compact camera solution with a dome casing. You benefit from its discreet, non-obtrusive design, and also from the fact that it is difficult to see in which direction the camera is pointing. In addition, the camera’s dome casing design offers efficient protection against e.g. redirection and defocusing.

Static Bullet Camera

Static Bullet Camera

Bullet cameras are often used in surveillance systems, named because of its shape and size. Bullet cameras are small (2 to 2.5 inches long) and are limited to a fixed focal length lens. While bullet cameras are good for small spaces, the images may have slightly cut-off corners because the camera shape and design can interfere with the actions of the camera lens and filter. Bullet cameras are also called lipstick cameras.

Several accessories are available, including joystick for easy maneuvering and mounting kits for indoor and outdoor installations.

Thermal Camera

Thermal Camera

Thermal network cameras are a perfect complement to any professional IP-Surveillance system that needs to secure an area or a perimeter in complete darkness.

Thermal network cameras create images based on the heat that always radiates from any object, vehicle or person. This gives the cameras the power to see through complete darkness and deliver images that allow operators to detect and act on suspicious activity – 24 hours a day, seven days a week.

Reliable detection as a complement

Thermal cameras are excellent for detecting people, objects and incidents in darkness and other challenging conditions. Thermal cameras do not, however, deliver images that allow reliable identification – that is why thermal cameras and conventional cameras complement and support each other in a surveillance installation.

Thermal cameras do not require any additional light sources – conventional or IR – that consume energy, create shadows and reveal their locations. And, in contrast to conventional day-and-night cameras that depend on a certain amount of near-infrared light to function, thermal cameras deliver reliable surveillance images even in complete darkness.

Enhancing any professional IP-Surveillance system

Thermal cameras can handle many difficult weather conditions better than conventional cameras, e.g. allowing operators to see through smoke, haze and dust. Thermal cameras typically also provide better accuracy in intelligent video applications.

With affordable IP-based thermal network cameras from Axis, thermal imaging is a realistic option for enhancing any professional IP-Surveillance system.

CCTV DVR

CCTV DVR

A digital video recorder (DVR) is a device that records video without videotape to a hard drive-based digital storage medium. The term includes stand-alone set-top boxes and software for personal computers which enables video capture and playback to and from disk.

CCTV NVR

CCTV NVR

A Network Video Recorder or NVR is an internet protocol based device that sits on a network. Because they are IP based, Network Video Recorders can be managed remotely via a LAN or over the Internet giving greater flexibility. The basic function of an NVR is the simultaneous recording and remote access of live video streams from an IP Camera.

One of the trademarks of Network Video Recorders is their ease of use and installation in Windows or Linux environment. Typically, a Network Video Recorder will feature flexible recording and playback capability, an optional intuitive remote control unit, a user-friendly graphical user interface, Intelligent Motion Detection, and PTZ camera control.

Megapixel and HDTV Camera

Megapixel and HDTV Camera

Megapixel and HDTV technology enables network cameras to provide higher resolution of video images than analog CCTV, i.e. the ability to see details and to identify people and objects – a key consideration in video surveillance applications. With a megapixel or HDTV network camera, the resolution is at least three times better than an analog CCTV camera.

Combining megapixel/HDTV network cameras with a selection of non-megapixel network cameras that are optimized for other needs (such as powerful optical zoom, extreme light sensitivity or low cost) creates video surveillance installations that are effective, reliable and cost-efficient.

What do you need to see?

Megapixel and HDTV network cameras have an important role to play in video surveillance applications. They are obviously more suitable for some areas than for others. The determining factors are ultimately the requirements of the individual customer’s system. Once the specific objectives for each network camera in the surveillance application are set, the right type of camera can be selected for the best fit.

Naturally, the variation of requirements within video surveillance is enormous. The most fundamental question, however, is generally a choice between two different priorities:

General overview

In this case, the aim is to obtain a general overview of a scene. In a shopping mall, for instance, your primary goal of a camera installation may be to watch for the presence of people and view their movements not the identification of individuals. Or you may want to see whether a parking lot is full or has empty spaces, rather than identify individual cars or read license plates. For overview applications, sufficient resolution and coverage of a scene may be achieved with a single megapixel/HDTV network camera or a number of non-megapixel network cameras.

High detail

These are the really demanding situations where you need to be able to identify persons or objects in a scene. This could be point-of-sales monitoring where it is necessary to clearly see every item a customer is purchasing or situations where you need to be able to identify a face. High detail images can be achieved by installing a network camera with a telescopic lens or a lens with zoom capability to allow a closer view of the area of interest, or by placing the camera close to the area to be monitored. Using a megapixel or HDTV network camera in all such cases will provide even higher resolution images with more details than a non-megapixel network camera.

Pixels per foot – Best Practices

A conventional CCTV camera providing 4CIF resolution offers a resolution of 704x480 pixels (NTSC) or 704x576 pixels (PAL) after the signal has been digitized in a DVR or a video server, which corresponds to a maximum of 400,000 pixels.

In the surveillance industry, some best practices have emerged regarding the number of pixels required for certain applications. For an overview image, it is generally considered that 20 to 30 pixels are enough to represent one foot of a scene.

For applications that require detailed images, such as face identification, the demands can rise to as much as 150 pixels per foot. This means, for example, that you want to be able to strongly identify people passing through an area that is seven feet wide and seven feet high, the camera needs to provide a resolution of 1,050x1,050 pixels, which is slightly more than 1 megapixel.

To assess which network cameras you need (megapixel, HDTV and/or non-megapixel, including pan/tilt/zoom cameras) it is important not only to do the calculations as outlined, but also to survey the location to determine the number of interest areas, the size of these areas and whether they are located close to each other or spread far apart. Other considerations should also be taken into account; for example the availability of guards performing live monitoring, the need for light sensitivity, bandwidth and storage.

IP CCTV Surveillance System

What is a video encoder?

A video encoder (also referred to as video server) digitizes analog video signals and sends digital images directly over an IP network, such as a LAN, intranet or Internet. It essentially turns an analog video system into a network video system and enables users to view live images using a Web browser or a video management software on any local or remote computer on a network. It allows authorized viewers from different locations to simultaneously access images from the same analog camera, as well as network cameras if they are added to the system.

Benefits of network video surveillance

The digital, network video surveillance system provides a host of benefits and advanced functionalities that cannot be provided by an analog video surveillance system. The advantages include remote accessibility, high image quality, event management and intelligent video capabilities, easy integration possibilities and better scalability, flexibility and cost-effectiveness.

Remote accessibility

Remote accessibility

Network cameras and video encoders can be configured and accessed remotely, enabling multiple, authorized users to view live and recorded video at any time and from virtually any networked location in the world. This is advantageous if users would like a third-party company, such as a security firm, to also gain access to the video. In a traditional analog CCTV system, users would need to be at a specific, on-site monitoring location to view and manage video, and off-site video access would not be possible without such equipment as a video encoder or a network digital video recorder (DVR). A DVR is the digital replacement for the video cassette recorder.

High image quality

High image quality

In a video surveillance application, high image quality is essential to be able to clearly capture an incident in progress and identify persons or objects involved. With progressive scan and megapixel technologies, a network camera can deliver better image quality and higher resolution than an analog CCTV camera.

Image quality can also be more easily retained in a network video system than in an analog surveillance system. With analog systems today that use a DVR as the recording medium, many analog-to-digital conversions take place: first, analog signals are converted in the camera to digital and then back to analog for transportation; then the analog signals are digitized for recording. Captured images are degraded with every conversion between analog and digital formats and with the cabling distance. The further the analog video signals have to travel, the weaker they become.

In a fully digital IP-Surveillance system, images from a network camera are digitized once and they stay digital with no unnecessary conversions and no image degradation due to distance traveled over a network. In addition, digital images can be more easily stored and retrieved than in cases where analog video tapes are used.

Event management and intelligent video

Event management and intelligent video

There is often too much video recorded and lack of time to properly analyze them. Advanced network cameras and video encoders with built-in intelligence or analytics take care of this problem by reducing the amount of uninteresting recordings and enabling programmed responses. Such functionalities are not available in an analog system.

IP cameras and video encoders have built-in features such as video motion detection, audio detection alarm, active tampering alarm, I/O (input/output) connections, and alarm and event management functionalities. These features enable the network cameras and video encoders to constantly analyze inputs to detect an event and to automatically respond to an event with actions such as video recording and sending alarm notifications.

Event management functionalities can be configured using the network video product’s user interface or a video management software program. Users can define the alarms or events by setting the type of triggers to be used and when. Responses can also be configured (e.g., recording to one or multiple sites, whether local and/or off-site for security purposes; activation of external devices such as alarms, lights and doors; and sending notification messages to users).

Easy, future-proof integration

Easy, future-proof integration

Network video products based on open standards can be easily integrated with computer and Ethernet-based information systems, audio or security systems and other digital devices, in addition to video management and application software. For instance, video from a network camera can be integrated into a Point of Sales system or a building management system.

Scalability and flexibility

Scalability and flexibility

A network video system can grow with a user’s needs. IP-based systems provide a means for many network cameras and video encoders, as well as other types of applications, to share the same wired or wireless network for communicating data; so any number of network video products can be added to the system without significant or costly changes to the network infrastructure. This is not the case with an analog system. In an analog video system, a dedicated coaxial cable must run directly from each camera to a viewing/recording station. Separate audio cables must also be used if audio is required. Network video products can also be placed and networked from virtually any location, and the system can be as open or as closed as desired.

Cost-effectiveness

Cost-effectiveness

An IP-Surveillance system typically has a lower total cost of ownership than a traditional analog CCTV system. An IP network infrastructure is often already in place and used for other applications within an organization, so a network video application can piggyback off the existing infrastructure. IP-based networks and wireless options are also much less expensive alternatives than traditional coaxial and fiber cabling for an analog CCTV system. In addition, digital video streams can be routed around the world using a variety of interoperable infrastructure. Management and equipment costs are also lower since back-end applications and storage run on industry standard, open systems-based servers, not on proprietary hardware such as a DVR in the case of an analog CCTV system.

Furthermore, Power over Ethernet technology, which cannot be applied in an analog video system, can be used in a network video system. PoE enables networked devices to receive power from a PoE-enabled switch or mid-span through the same Ethernet cable that transports data (video). PoE provides substantial savings in installation costs and can increase the reliability of the system.
