The nature of an IP video signal uses a two way communication over two pairs of twisted wire usually packed into a 4 wire pair network cable with an outer jacket to hold everything together. The IP video signal uses a balanced transmission
A backup power generator for your broadcast transmitter is a necessity to guaranty continuous on air broadcasting operations and if the power generator is at a maned location it is a simple matter to send someone to the generator to make sure there is enough
Some of our customers have indicated that they would like to switch off a network IP camera under special circumstances with a simple switch that their customers could use. As it turns out that is not as simple as it seems.
Sometimes the CCTV installer is faced with the problem of being a few wires short when it comes to pre-wired hardware installations. Particularly if the wiring was done by another contractor or the installer is upgrading the installation and is expected to use the existing
IP camera use is gaining in popularity and more customers are asking for the latest thing in CCTV technology. The IP cameras have many benefits for the installer and the customer however they also have some drawbacks and special concerns that must be addressed. Perhaps
The S/N (Signal to Noise Ratio) specification may be found in many of the component specification sheets used in a CCTV system, so it must be important, but what does it really mean to you while choosing cameras and other components for a CCTV system?
All new technologies have a story, that is, the information needed to use the new technology seems to reveal itself in steps like the pages of a story book. And in these story books the characters are forced to make choices between good and evil.
A product called ATU-2 can be used to insert remote control relay signals onto the existing video signal to control access without impairing the video image. This product inserts the relay control signals into the vertical interval of the video image and recovers them at
IP VIDEO MARGIN is the amount of signal level above the digital cliff that you have in your system to prevent a failure from occurring. The question is how much margin is there in your IP video system, how close are you to falling off
LIGHTNING HAPPENS. You cannot control it, and when it happens near an IP Picture Transmission System, the differential current flowing in the ground and the twisted Pairs carrying the digital picture information can be enough to damage the terminating resistors in the system changing the
