On camera storage solutions

The market demands better image quality. When it comes to future-proof video surveillance systems in banks, it is not a matter of analogue or digital; it is a question of high resolution or not. Since high-resolution video can only be implemented cost efficiently (and even less expensive than any other kind of video surveillance) when decentralised network camera technology is deployed, centralised, analogue, low-resolution systems will gradually disappear from the market during the next few years.

It is a fact: high-resolution video produces more data and requires a powerful storage concept. These days, video data is normally pre-processed and stored centrally on a PC with video management software or on a DVR. Video and audio streams from all installed cameras are directed to this central device. This system is comparable to a highway at rush hour: the more cameras there are, the quicker there will be a data overflow on the PC or DVR. This means that despite high-resolution cameras, the data is generally not stored in high-resolution format.

Mobotix solves the storage bottleneck problem. High-resolution video images, including sound, are stored decentralised in or at the camera on flash memory media (normal 16 GB MicroSD/SD or CF cards, USB mass storage). Flash memory is mature semiconductor technology without any mechanical moving parts. Thanks to its reliability, ease of use and low cost, it is the storage medium of the future.

Stores data in flash memory

* No PC/network is needed for operations and there is no network load.

* Event-driven recording (eg, motion) also saves on storage.

* USB flash media can be connected directly to the camera (instead of internal MicroSD/SD/CF card); no network is necessary.

* The system is more dependable (no hard disk drive).

* Ring buffer: Old recordings can be overwritten automatically or deleted after a predefined period.

The BGV C 9 regulation requires two alarm memory areas capable of storing two images per second for 30 minutes plus one suspicion memory area capable of storing one image per second for about 10 seconds. Every camera in a Mobotix system, however, can even support up to four alarm memory areas, higher image rates and longer recording times – and these can only be cleared by authorised persons. This enables optimal monitoring of locations with heavy customer traffic.
