pablo147 0 Posted August 26, 2018 Am not getting any video only black screen display from my 4 bullet cameras which have illuminated red LEDs at night. This is the situation with a new power supply unit as the old one failed after 2years continuous use. The DVR is a kare H 264 type and gives no video with the hard drive disconnected. Any advice will be appreciated. Share this post Link to post Share on other sites
