In principle and in most cases yes. In practice, it depends on your equipment characteristics and the area to be monitored. Meleagros video detection software is made so that it can work with any type of camera having some minimum characteristics: can provide IP stream, VGA resolution, 15 FPS.
Another point to consider, when re-using already installed cameras is whether they can cover the required area: fire monitoring usually has different coverage requirements than surveillance or security applications.
In any case, you should keep in mind that although we work with some camera vendors, we always help our clients to minimize costs through reusing equipment so that the system's Total Cost of Ownership (TCO) is reduced and the Return On Investment (ROI) is increased.
