Security system installers, this one's for you! This HD CCTV video distributor takes one input and splits it into two outputs without losing any video quality. We're talking serious 4K resolution support here - it handles HD-TVI, AHD, HD-CVI, 960H, plus the standard NTSC and PAL signals. The specs are pretty impressive: 350 MHz bandwidth, BNC connectors, and it operates with video input level of 0.8~1.2Vp-p. It's compact too - measures just 57.8 x 49.2 x 41.7 mm and weighs only 70g. They've included TVS protection built right in, so your equipment stays safe from voltage spikes. Power supply's included in the package, which is nice - it runs on DC12V 500mA. Works in temperatures from 0ºC to 55ºC and handles humidity up to 95%. Honestly, if you need to distribute your CCTV signal to multiple monitors or recording devices without compromising that crisp 4K quality, this little box is exactly what you're looking for. Super easy to install and just works reliably day in and day out.
