Recommendations on network camera system-OP added notes on 12/17

1,179 922 December 12, 2017 at 02:13 PM
Where I work, we have an 8 channel dvr with POE cameras. When you view the cameras on either a monitor or on your phone, the pictures from all 8 cameras are full of static/snow etc.

The boss wants me to look into replacing the system this year.

We are in a metal building about 4800 sq ft. There are several small offices in the front, and the back is warehouse space.

The system would need to be a least 8 cameras and be accessible on a phone or tablet.

Thoughts? Recommendations?

**UPDATE** 12/15/17
Here is a pic of what we see on the monitor that displays the camera system

The 2nd pic is a google map view of our building. I have marked 12 areas that we would like coverage. I know you can't see inside the building, but this is where we are looking to put a new system

The 3rd pic shows the location of exterior doors

There is a user, mat2000, that seems to be knowledgeable about security cameras. I was in a lot of Arlo Pro threads and he was always there with some answers and has posted other posts with lots of info on PoE cameras, wired, wireless, etc. Below is a post he started about Black Friday deals for security cameras but it also has some info. Maybe try messaging him directly in response to one of his posts or with the inquiry from your post here.

Network cameras shouldn't really look like the static or snow from the days of analog tv. I think the first step should be identifying what you've got and trying to figure out why it looks the way it does.

The easiest way to do this would be to post some pictures of the dvr (make sure the back is one of them), a camera or two preferably showing the back / connections, and an image showing the snow/static you're describing.

Poe adds no interference...please, stop posting nonsense...even if there was interference it would not appear as snow....

Well that's unique. I've never seen a network camera system that looked quite like that. I asked to see a picture of one of the cameras and the back of the dvr because I was curious what model they were and wanted to make sure it was a networked system and not some monstrosity using baluns.

Here are a couple things you could try:
- Power down the dvr, unplug all cameras, power up and try plugging in each camera one at a time (only one connected at a time)
- Connect a camera to a PoE switch or injector and see if it functions and you can access its web interface.
- Take down a camera and connect only that camera directly to the nvr with a short cable
- try to view cameras from the DVR's web interface

I realize your plan is to just replace everything (which does make sense), but putting in a bit of diagnosing effort now could save you from bigger hassles later if there's some sort of major interference or cabling issue.

There are other forums that are more focused on security cameras. If I remember correctly fenderman runs https://ipcamtalk.com

I doubt those are poe cams, I have never seen anything like that on an ip camera, more likely they are HD over coax...as jkee mentioned, take a photo of the back of the nvr/dvr and cams and post model numbers.

Iagree
Only time I've every seen anything like that was with analog video and it wasn't security cams.

Robintrade, you should probably plan on having to replace all the cabling.
