A companion to ACTi cameras
There is no all-purpose CCTV camera. The comparison below allows to choose an optimum camera for a specific application, from the wide range manufactured by ACTi. The cameras have been grouped according to resolution - megapixel, D1, VGA.
Megapixel cameras are quickly gaining popularity. They set new quality standards in video monitoring, not achievable in previous systems based on analog cameras and typical DVRs. Let's compare a standard D1 camera (720 x 576 = 0.4 Mpix) and "typical megapixel" ACTi camera (1280 x 1024 = 1.3 Mpix) - the latter provides 3 times as much information.

Compressão H.264 - aprender e usar, na prática
Atualmente, a compressão H.264 tornou-se um padrão em gravadores de vídeo digital (DVRs). Os dispositivos mais avançados permitem ao usuário controlar a taxa de compressão e muitos parâmetros do fluxo de vídeo injetada na rede. Para entender o impacto das mudanças e os intervalos permitido, os usuários devem conhecer os princípios gerais deste método de compressão de vídeo.

Optimization of CCTV camera settings
When selecting a model of a camera we are usually interested in possibility of adjustments to various operating conditions. Of course, more advanced models have more capabilities, simpler devices keep some parameters fixed.
However, in order to be able to take full advantage of the adjustments, please refer to their technical data and user manuals. We are here discussing a number of typical settings having an impact on the quality of the image, both positive and negative. Such knowledge will help you achieve the best practical results of the camera operation.

LAN for IP video surveillance
How to design, install, and operate LANs used for transmission of video data (IP CCTV). Video surveillance systems based on IP CCTV devices need adequate IP networks for transmitting video data and providing communication among the devices and computers or transcoders. IP CCTV devices send video or video and audio in the form of data stream, usually compressed in MPEG-4 (SP, ASP, AVC/H.264) or MJPEG format. Compression limits the required band. However, the quality of video and audio strongly decreases with higher compression ratios. Some applications may require full resolution (e.g. ...
