Few months ago my internet speeds suddenly diminished from 25mbps to a sluggish 3-5mbps. ATT tech came out and said he was getting 25mbps at the house connection...I have a fairly large wired lan with a few wireless access points and ethernet switches so it took me some time to isolate the issue...I even bought all new network switches. It came down to my CCTV DVR. I could watch the speed drop off and come back to speed as I plugged in or removed the ethernet connection. I had four cameras hardwired to the DVR..Don't remember the brand of DVR but it worked well for a few years. I bought another DVR, installed, set it up, and worked well for a few months until recently the same thing started happening with this DVR! Same deal with slow speed for the whole network when plugged in.... Amcrest HDCVI DVR with 4 cameras Static IP set for DVR. Login and password changed ATT uverse internet with Pace gateway Wifi turned off at gateway and broadcast through Ubiquiti access points Amcrest "support" was useless. Thanks for any help!

sorry, it just says 75 ohm with no apparent way to change it

manual says 75 ohm

Wanted to add that the distributed video from the PCI-card DVR was fine. This has to be in the output from the new DVR. Im using a BNC to RCA adapter with an RCA ended patch cord to the modulator.

Previous system, residential,four cameras, Nuvico stand alone DVR. Output from DVR fed to modulator which is fed through a video distribution panel (consisting of appropriate video amplifiers, low pass filters and attenuators) I don't have my original schematic anymore but for the last four years it has worked perfectly with a crystal clear picture on any TV in my house. So my DVR's hard drive quit so I put a PCI-based card in a computer to take over. I messed with it for a couple of months and wasn't real happy. (it kept crashing the computer) Next bought a new stand alone DVR (el cheapo) that seems to work just fine except for one issue. It has two outputs: one VGA and one BNC. The VGA output works perfectly to a monitor I have nearby and the BNC output works fine when hooked up to the monitor. FINALLY TO MY PROBLEM... when I hook the output from the BNC out to my modulator, which goes on out to the video distribution. The picture is very washed out when viewed on remote TV's. Almost like the output power is too low. Would the output power be that much different from one DVR to the next? Tried an in-line amp between the output and the modualtor. No change. Thanks for the help!
