SADP application - tool for integrating CCTV systems based on HIKVISION equipment
SADP (Search Active Device Protocol) is a simple tool designed to support ULTIMAX and ULTIMAX-Hikvision DVRs, ULTICAM cameras, ULTINET video servers - with a PC connected to the same local network (LAN). It allows to manage the network parameters of the DVRs, IP cameras, and video servers. The software runs on Windows XP/Vista/7.

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.

H.264 compression - learn and use in practice!
Currently, H.264 compression has become a standard in digital video recorders (DVRs). The most advanced devices enable the user to control the compression ratio and many parameters of the video stream injected into the network. To understand the impact of the changes and the allowed ranges, the users should know the general principles of this video compression method.

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.

Operational requirements for CCTV systems
The article is based on the resources published by British Home Office. It describes the features of CCTV system which are important for its users. With many years of experience, the Home Office has developed a set of requirements on the use of monitoring systems by the police in various investigations. To be able to effectively use the material obtained through a CCTV system, it must meet the requirements set out below, collected in four sections: Quality, Recording, Export, Playback.

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. ...

Concepts of monitoring with ACTi: IP solutions and equipment
ACTi Corporation belongs to the leading manufacturers of monitoring equipment based on IP technology. The offer includes IP cameras, IP speed dome cameras, videoservers, video transcoders. IP cameras encode video signal to MPEG-4 data stream, which can be further transmitted within whole computer network, received and processed by any "entitled" network device. It means that the image can be viewed and recorded in any place where there is a PC connected to the network and equipped with appropriate software.

IP Monitoring with ACTi - Questions & Answers
IP is the acronym of Internet Protocol, the most popular protocol used for communication within any computer network or the Internet. IP camera provides at its output digital stream of data corresponding to the video information, which is being transmitted via wired or wireless IP networks, and can be viewed or recorded even in most remote locations in the network.

What is DDNS (Dynamic Domain Name System)
and how to use it?
and how to use it?
Translation of the domain name into the set of numbers is performed by the appropriate DNS server, to which the computer sends a request for the translation of the address. After receiving the response with the numeric address, the computer connects to the relevant computer/server.
