With the increasing concern over better protecting people and assets, security departments are required to provide a higher level of security than before: proactive prevention, better situational awareness, earlier detection, quicker identification and prompter action. Conducting well-planned surveillance, training security staff well and ensuring good communication between all related parties is essential. Video surveillance has also become essential. Now many organizations are continually reevaluating and enhancing their video surveillance to provide optimal daily security and operational efficiency.

If you are considering the enhancement of your analog video surveillance, upgrading your analog system with the latest IP technology will increase effectiveness and efficiency. A proper update plan avoids extra costs and unwanted problems, protecting your investment in the analog system. This paper provides guidelines for a successful upgrade and migration to a future-proof IP video surveillance system for Panasonic and non-Panasonic analog system users.

IP technology benefits

2.1 Market trend

Technology drives business success more than ever before. Open standard-based IP and High Definition (HD) video technologies definitely have had the greatest positive impact on video surveillance. Analog systems were good but IP systems are is the future. (The graph is created by Panasonic based on reliable information.)

2.2 Analog video surveillance
First, let’s examine the difference between analog and IP systems. The diagrams on the next page show typical analog systems. The indoor/outdoor analog cameras, analog monitors and Digital Video Recorders (DVRs) are connected to each other through an analog matrix switcher that switches video inputs to monitor outputs. Most DVRs for small systems have some switching functions as well as a recording function. Much coaxial cable is required to connect analog equipment. Analog video surveillance systems are simple, but they offer very limited functionality and expandability.

IP Video surveillance

IP system diagrams are similar to IP-based data networks such as corporate networks and the Internet. All equipment, such as indoor/outdoor IP cameras, is connected by Ethernet (LAN) cables. An IP Matrix Server or Video Management System (VMS) manages the whole system. IP video surveillance can be easily networked with other sites, mobile devices and other systems such as face recognition systems. In a small installation, most Network Video Recorders (NVRs) have some IP Matrix Server/VMS functions. The IP video surveillance systems are open, feature-rich, flexible, scalable and easy-to-use.

Analog, IP or composite solutions:

to identify the solution which is best suited to your requirements, you should:

  • define the areas of major safety concerns and detail what is to be monitored;
  • for each area that needs to be monitored define the detail of the images in question (image quality) and the level of lighting;
  • define the basic characteristics of the video cameras;
  • consider the advantages of a wired structure in regards to the traditional structure.

Thanks to high definition (HD et Full HD), a scene filmed in “recognition” mode can be zoomed to enable persons to be identified.


Guarding of property

Allowing an area to be open to the public while providing protection against theft in shops, car parks or enclosures.
The CCTV system facilitates live or delayed (when recording) monitoring of one or more areas of the building.

  • Enclosure, car park, sales area, etc.

Access monitoring

Monitoring access to buildings or premises outside opening hours can not only detect intrusions, but also trace incidents or malicious acts.
During periods when the building is in use, the CCTV system enables you to manage the opening of accesses by detecting the presence of a person near to an exit, or by working in conjunction with visitor access controls.

  • Recording access to a building

Event monitoring

When connected to other systems installed in a building or premises, the CCTV system can display the images from a camera associated with a specific event.

  • Intrusion: immediate verification and recording on detection of intrusion

  • Fire: verification of the presence of fire in the area concerned

  • Technical alarm: verification of a technical problem with the machinery


The main function of a camera is to film a scene live.

For example, it may be interesting to show customers in a shop that the premises are monitored by CCTV by visibly displaying the images on a screen connected directly to a camera. Besides being a deterrent, it allows shop workers to keep an eye on one or more scenes from a single location in the store.


Depending on the sensitivity of the scene to be visualized (or the type of building), it may also be necessary to save the images. This enables you to review the events that take place in order to better interpret them (in the case of shoplifting, for example).

Be careful not to fall into the trap of continuous recording: in addition to (relatively) quickly filling the hard drive, it also complicates the search for a specific event among the recordings.
Recordings should be programmed, as is relevant, focusing, for example, on access to the site during certain hours.

Visualizing and analyzing

Whether it is accessing the video channel for one or multiple recorders or accessing their recordings, it is possible to install dedicated video surveillance software at one or more locations (e.g. control station, police station, etc.).
Visualization can also be performed from a remote location using a smartphone or computer to enable monitoring at your leisure.



This is to monitor and record just a few areas (usually the main entrance, product display area and cash register). An effective solution is offered by CCTV kits, expandable up to 4 cameras. Simple and discreet, thanks to their compact size, they allow remote viewing.


This type of establishment necessitates the monitoring and video recording of numerous small and large areas, both internally and externally. The usual requirements for external areas are: surveillance of the stock loading/unloading area and car parks. The internal areas to be monitored are:

the product display areas, check out and warehouse. The solution is a bespoke design where all devices are monitored and controlled from a monitoring station.


This type of establishment necessitates the monitoring and video recording of various small and large areas, both internally and externally. The usual requirements for external areas are: surveillance of stock loading/ unloading areas, the sides of the building and parking lots. The internal areas to be monitored are: the warehouse and the loading/unloading area.

The solution is a bespoke design, where all devices are monitored and controlled from a local switchboard or a reception, with an operator present during the day. If necessary, it is possible to centralize the remote management of several sites.


When installing a simple CCTV system, we recommend that you follow the four steps below. If the installation has to meet stricter safety requirements, please contact your local Legrand sales office.

The figure opposite shows the relative size of a person (target) on the screen.

Step 1


Perform a study with your client using a map of the area to be monitored.

Step 2


The expected results should be agreed with the customer for each area to be monitored. In most cases, this will be one of the following objectives: identification, recognition, detection of intrusions.

For a description of the expected results, please refer to standard EN 50132-7, of which the following is an extract:

The size of an object/target on the monitor screen should have a relation to the operator task, for example: identification (facial identification), recognition (complete identification) or monitoring (overview).

If the target is a person and the CCTV system has an installed limiting resolution of better than 400 TV lines, the recommended minimum sizes of this target are:

a) for identification (facial identification), the target should represent not less than 120% of the image height.
b) for recognition (complete identification), the target should represent not less than 50% of the image height.
c) for monitoring (overview), the target should represent not less than 10% of the image height.

The figure opposite shows the relative size of a person (target) on the screen.

Step 3


The quantity of results expected determines the number of cameras required. For each camera, the most suitable installation position must be identified according to the following parameters: the size of the objects to be observed (expected results), the distance between them and the installation requirements for the camera (internal/external, wall/ceiling/flush-mounting, etc.).


Ensure that the cameras are used in accordance with the laws and regulations in force, both in terms of privacy and staff safety. The images, sounds, voices and names recorded are personal – and sometimes sensitive – data – which may also be protected by copyright or third party intellectual property rights.

Therefore, any person using the equipment must comply with the following:

– strict compliance with legislation regarding the protection of personal data;
– respect for data security obligations;
– respect for image and representation rights, as well as all requirements in terms of copyright and intellectual and industrial property rights. Legrand cannot be held responsible for any illegal use of its products by its customers.

Step 4


It is now possible to identify the necessary products for installation of the system: cameras, video recorders, screens, accessories.


Once all the information from the previous step has been gathered, it is possible to identify the most suitable compact cameras, using the simple user tables provided for this family of products. If compact cameras cannot be used due to the requirements of certain applications, high performance modular cameras are also available. For each one, it is possible to select the most suitable accessories (e.g. supports, housings, IR illuminators, lenses).


To be selected based on the number of cameras to be connected and the secondary functions provided.


To be selected based on display dimensions and available space.


As the cameras do not all offer the same “visualisation” function, it is important to carefully select an appropriate camera, taking into account the following points:


Waterproof products (IP 55 or IP 66) can be installed outdoors. If there is a risk of defacement, products must be vandal resistant (IK 10). Compact and modular cameras remain visible, while dome cameras, mini-cameras and hidden cameras facilitate covert surveillance.


How far is the scene to be filmed from the location where the camera is to be installed? What are the dimensions of the scene to be filmed? Are the dimensions fixed and precise (door or entrance)?
-> Fixed or adjustable focal length.
Are the dimensions variable (wide angle and zoom)?
-> Camera with zoom or high resolution camera (megapixels).
Is the scene wider than the camera’s field of view?
-> Motorized dome camera


Install the cameras at a height of 3 to 4 meters. The camera stand (housing, support, etc.) should enable it to be electrically insulated from the ground (to avoid ground loops). The camera must be connected to the power supply with strict regard for phase and neutral, as cameras connected to alternating current (230 V) use the network’s 50 Hz frequency for synchronization: if all the cameras are connected correctly, they will also be synchronized.

Performance of the lighting systems strongly depends on the type of surfaces illuminated (reflectance) and the spectrum of light generated. When choosing the type of camera, you should take into account the fact that color cameras require 10 times more light than black and white cameras. The amount of light on the scene to be observed should in practice be 10 times the minimum quantity of light required by the camera. The reference parameter to consider in order to choose the correct camera based on the available light is the “sensitivity” of the camera. The following table gives the brightness values for certain specific conditions.


Insofar as it is impossible to constantly monitor all installations, scenes should be recorded for later review. Digital video recorders complete a CCTV installation and must be chosen according to the following criteria:


The type and number of recorders are determined by the number of cameras for which images must be recorded. However, in cases where the number of installed cameras is expected to increase, we recommend that this upscaling be taken into account by choosing a recorder with a larger number of inputs. When the total number of cameras is greater than or equal to the capacity of a 16-input recorder (analog or IP), it is still possible to use one (or more) central management point(s) as long as the recorders are connected to the same network (local or remote).


Whether you want continuous or event-related recording, the duration of data retention and image quality determine the size of the storage medium (hard disk). Some recorders also offer the ability to add hard disks, while others do not.


The installation location of the recorder is an important factor to bear in mind: need to access the controls on the front (or vice versa), installation in a computer cabinet or housing, direct installation into a rack.


Analysis or verification of a scene may be performed:


The image from the camera is transmitted to a screen or to another remote video support.


The image is stored by the recorder for viewing on demand. However, it is possible to combine the two modes of use, i.e. a recorded scene can be displayed directly on the screen.


The screen is connected directly to the camera or the recorder.


Internet-based visualization via a PC or a smartphone.


The recorders allow simultaneous viewing of multiple video channels on one screen (windowing).


This function ensures the link between the above functions. You should select whether the installation will be analog or IP:


Via coaxial cable:

this is an easy to implement solution requiring no additional programming or products. The length of each connection is limited to 300 m.

Via twisted pair (FTP):

this can be integrated into the structure’s wiring and enables you to switch to an all-IP solution. Transmitters and receivers (baluns) must then be installed at each end of the connection. By using amplified transmitters and receivers, the length of the connection can be increased to 1200 m. The power supply to these units is typically 12 V and can be provided:

– Via an independent power supply for each camera, located close-by.

– Via a centralized power supply for multiple cameras. Connection to the above system can be achieved using composite cables integrating the coaxial cable and two power cables. Choosing twisted pair (PoA) for powering analog cameras enables migration to an IP or PoE solution when connecting to the same network (local or remote).


Via twisted pair (FTP):

enabling the installation of several other cameras if the IP installation has been correctly dimensioned. The power supply to these units is typically 12 V and can be provided:

– Via an independent power supply for each camera, located close-by.

– Via a centralized power supply for multiple cameras. Connection to the above system can be achieved using composite cables integrating the coaxial cable and two power cables.

– Via the network, if it is PoE (Power over Ethernet) compatible.


Advanced automatic path:

Similar to the single automatic path function, except that the movement follows a path which can be programmed in any direction.
For example, it can be programmed by saving a manual path from the control station.

Compact or all-in-one:

Camera supplied with lens and mechanism already affixed. The form of the mechanism allows for wall-mounting and it is usually equipped with protection to prevent rain water from entering.


Camera supplied with lens and mechanism already affixed. The format of the mechanism allows mounting on the ceiling or a suspension arm. The translucent dome masks the camera angle.

Fixed Focus:

Lens with fixed focal length and camera angle.

Focal length:

This value, measured in millimeters, is directly related to the angle of observation. A short focal length offers a wide-viewing angle, while a long focal length offers a telephoto effect with a smaller viewing angle.

Image quality:

An image is defined by its resolution. There are 6 formats (the values in brackets are in pixels):

QCIF (176 x 144)
CIF (352 x 288)
2CIF (704 x 288)
4CIF (704 x 576)
HalfD1/HD1 (360 x 576)
D1/fullD1 (720 x 576)
HD 720 (1 280 x 720)
HD 1 080 (1 920 x 1 080)
WD1/960H (960 x 576)
HD 720
HD 1080

Mini-camera :

The camera is supplied complete with lens and can easily be concealed because of its small size.

Modular camera:

Camera supplied without lens, so an appropriate lens can be affixed.

Motorised camera:

Camera capable of extremely fast movement. It can change position very quickly and follow the movements of any object/target.

PoA (Power over Analog):

Supplies power to an analog camera via a twisted pair cable. Requires the installation of balloons at the camera.

PoE (Power over Ethernet):

Supplies power to an IP camera via the network cable. Requires the installation of a PoE injector as power supply.

Recording quality:

The recording quality depends on the resolution of the recorded image and the number of images in one second of recording.

Resolution :

The resolution indicates the quality of the image reproduced. The quality of the image captured by a camera is defined by the number of vertical lines. The current industry standard regarding the resolution of CCTV cameras is 330 lines for color cameras and 380 lines for black and white cameras. The number of lines that a camera must produce to be termed a “high resolution” camera is not defined by any
standard. According to current manufacturing standards, a “high resolution” color camera generally provides more than 420 lines, while a “high resolution” black and white camera provides more than 480 lines.


This refers to the camera’s ability to reproduce a video signal with a particular brightness value, which is the minimum amount of light (measured in lux) necessary to obtain a video signal. The higher the sensitivity of the camera, the lower the quantity of light required to obtain a video signal. A high-sensitivity camera will also require less light to obtain a good video image. Be careful not to confuse the minimum required quantity of light (sensitivity) with the ambient lighting. Although these two values a re both measured in lux, the amount of light detected by the camera is that reflected by objects and not that coming from the ambient lighting.

Simple automatic path:

the motorized camera moves automatically along a programmable path that is repeated cyclically. The movement follows linear paths between predetermined intermediate points.

Types of screen connection:

The maximum resolution depends on the connection type.

Coaxial: 720 x 576,

VGA: 1024 x 768,

HDMI: 1920 x 1080


Lens which enables manual adjustment of the focal length. These lenses are designed to be light and compact and can be used in numerous situations. For example, if a 6 mm fixed lens is required, a 3.5-8 mm varifocal lens, adjusted to be fixed at 6 mm, could be used.


Lens which enables the physical characteristics of its focal length to be modified in order to cover a great distance. These lenses are classified according to their magnification (x6, x10, etc.). Manual and motorized versions are available on the market.
