SURVEILLANCE CAMERAS

The key question is whether to opt for analog cameras or IP cameras. Images from quality IP cameras are even sharper than those from analog cameras, but at a slightly higher cost. In most cases, analog cameras are easily sufficient for a variety of uses.

About analog cameras:

Installations with black and white analog cameras are less common than was previously the case. They have been overshadowed by the greater resolution provided by colour cameras. However, it is clear that colour cameras need more light when providing images that can be used at night. It is therefore recommended to select day/night cameras for locations with poor lighting. These cameras switch over to black and white when light levels are reduced, thus making it possible to obtain clear images despite poor lighting conditions. Using cameras with integrated infrared lights (infrared LEDs) is another option available today. LEDs make it possible to obtain clear images even in poor lighting conditions. Analog cameras are used with a coaxial cable. UTP cables can also be used (for IP cameras) if quality converters (signal converters) are added to each end of the cable.

About digital cameras:

IP cameras provide superb images. They have integrated technology required for long-distance zooms. Specific parts of images can also be selected and then enlarged using the appropriate software. This technology is most frequently used to identify car registration plates or even a single person in a crowd. The sharpness and clarity of an image depends on the number of pixels. If image precision is important, the best results are obtained by using fibre optic connections. IP cameras are subject to software licences that must be procured by the end-user..

About digital recording systems:

The digital recording systems have a similar price to the former 24-hour time-lapse recorders. Nowadays, for €750 you can buy a digital recording system with four cameras and a storage capacity of between +- 300 to 500 GB. They have a recording speed of 100 PPS (picture per second) divided by the number of cameras used. The images can be viewed on-site or can be recovered via the Internet from any location. As IP cameras become increasingly popular, with a view to avoiding having to make laborious changes to all analog cameras, the market is making provisions for hybrid recording systems. Hybrid systems include recordings from analog and IP cameras. Pursuant to Belgian legislation concerning cameras, recorded images can be conserved for a maximum one-month period. You must also notify the Private Life Commission that you have such a system. You will find more information on this subject in another section of this website (news: legislation).

The cameras can also operate in a closed-circuit. Our closed-circuit equipment is procured from the most highly-regarded brands such as Panasonic, Sony, Vantage, Vista, Samsung, etc.

Because of the rapid developments of this type of CCTV equipment, we only provide an outline of our various options. These models are available using the highest quality brands and with the following options in terms of use and characteristics:
 
  Example of an analog day/night camera with an infrared 42 LED and a lens that can be adjusted from 3.8 mm to 9.5 mm positioned in a housing for external use.
  Example of a dome camera. These analog cameras are positioned in discreet housing. They are ideal for commercial use so as not to alarm customers. They are also available with a day/night system and an integrated infrared LED. Advantage: it is difficult to cover this type of camera.
  Example of a discreet analog camera with a ‘pin-hole' lens. These small cameras can be built into all types of materials. However, care must be taken to comply with the legislation in force regarding the use of security cameras.
  Example of an IP camera. This is a Honeywell 3.1 Megapixel model. Sensor: 1/2 inch progressive scan, Resolution: max 2048x1536, Sensitivity: 0.3 Lux, Lens: 4.0 - 10mm, Compression: Motion JPEG, Power supply: 12VDC, 24VAC, PoE, I/O alarm connection.
