Modern functions of ACTi cameras
IP CCTV equipment manufacturers are constantly looking for higher resolutions, higher numbers of transmitted frames and improvement of other parameters, often forgetting about the users, unable to fully utilize the improvements. Simply - better performance does not go hand in hand with additional features that allow the users for optimal configuration of cameras in order to maximize their potential in practice.

Designing SMATV systems with SatNet software from TERRA
This article aims to explain the principles of designing satellite master antenna systems, with the use of very valuable and free SatNet2.0 software from Terra company. SatNet2.0 is a simple to use program with a great interface and versatility. It is possible to design a network with a virtually unlimited number of outlets. Simulation results correspond very well with reality.

Optical power budget in a fiber-optic communication link
The most important task in the design of fiber optic link is to determine the maximum range of the optical transmission path, being in fact the balance of optical power in the link. Balance of power is a comparison of the power at the input of the optical link with the losses in fiber optic cables and other path components. This will help to find the optimal parameters of transmitting and receiving devices to ensure proper signal transmission.

FAQ - GSM, DCS, 3G amplifiers/repeaters
Mobile phone conversations in buildings are often difficult, if not impossible. This is due to the signal attenuation through walls, window panes, ceilings (underground). The problems occur in markets, tunnels, underground car parks, petrol stations, airport halls, hotels. A similar situation can be found in buildings located on the border range of base stations (recreational areas, mountains etc). The solution to such problems is application of GSM, DCS, 3G repeaters, being two-way amplifiers of cellular signals.

Library of Megapixel ACTi Video Clips
IP CCTV systems are still gaining popularity. The main cause of this phenomenon is practically unlimited image resolution, which means that any area can be watched by a camera with any available resolution, up to many megapixels. In systems based on analog cameras, image resolution could not exceed 720 x 576 pixels, i.e. about 0.4 Mpx. Popular ACTi cameras operate at the resolution of 1.3 Mpx, at least three times better. The advantage can be clearly seen in the real images recorded with the cameras.
Below there are links to video files recorded with the use of ACTi megapixel cameras.
