Do not buy from Silicon Valley Peripherals! or SVP or SVP cameras… they are using their camera systems to creep on you and their family! Not only are they utterly expensive but I hired an IT person from this company to install their cameras and while he was on the job he was fired. The poor guy finished installing our cameras but told us how SVP was using their security camera system to watch people and watch when they went out of town! We had to hire a geek squad person to figure out a new system to get off their camera servers but still use the cameras since they were enot returnable! These guys are crooks! STAY AWAY FROM THEM.
