Talk about SD and HD project installation depends on the points

www.headwaybatteryandcable.comBeginning in 2009, the monitoring system into the fiber optical cable Wholesalers network digitization stage, D1 (72-480) is becoming the standard of IP video surveillance with SD (StandardDefinition, referred to as SD), that is the standard analytic argument, the next due to picture detail more pursuit, and therefore china optical fiber cable will produce HD (HighDefinition, HD), also known as high-resolution. Later, in order to comply with the digital television (HDTV), 16:9 wide screen display format, then jumped to 720p and 1080p HD HD Castles format.

For the maintenance of the UPS battery status and technical description

UPS battery maintenance necessity UPS uninterruptible power supply, because when the power outage, it can quickly convert to the inverter status, so as not to let the computer use to lose important documents because of the sudden loss fiber optical cable of power is not enough time storage. Not be used when the standby power, if you just want to blackout, electricity, light enough to buy an inverter. The general household UPS with the most maintenance-free lead-acid batteries. UPS uses the same battery technology, different manufacturers large battery life is not the same, this is very important for users, because of the high cost of replacing the  optical fiber cable battery (approximately 30% of the UPS price). Battery failure reduces system reliability, which is a very annoying thing. At present, small and medium-sized UP ...
