crapped out after 90 days
Hard drive stopped working after 3 months. Camera connections are sloppy and as a result the unit often loses the video signal. Likewise the ac input is sloppy and if bumped the unit loses power. The cameras work fine but the DVR function is apparently very cheaply made with an inferior hard drive. I do not advise buying and I would not buy again.Update: I replaced the hard drive and all is fine - likely they are using cheaper hard drives - since I replaced the hard drive it has been working fine 24/7.
