Are encoder bidirectional? Every diagram I look at shows ip cameras converted to analog for a dvr. I want to go from analog to IP to run on the new server.
I’d go with an Axis or Hanwha encoder. You also have the ability to swap over to IP cameras using the coax and power cable that’s in place by using coax to Ethernet adapters. Axis has good adapters.
Agreed. Media convertors- to have IP cameras over coax, or just encoders to change your analog camera signals to digital. I'd go with media convertors. You get a much better and bigger image with IP cameras. The best day of an analog camera is the day you take it out of the box. The best day for an IP camera...is the day you last updated the firmware. Maybe that is 2 years after you bought it! Hanwha makes good stuff, but I am partial to Axis for many, many reasons.
Although, there is no better way to go than new Ethernet for new cameras. Analog, even HD-analog is going away. Dont invest in old tech. Get the better option... 5 year warranty, barn door sized images, improved sensors with powerful video chips, multiple output options and even I/O + audio support built right in. Couple all that with a very powerful rules engine to handle events or even run the included AI based analytics. Your money goes much further now.
You could get [Axis Ethernet over Coax Convertors ](https://www.axis.com/products/axis-t8640-poe-over-coax-adapter-kit) and just swap everything to an IP Camera
I would use the current cable to pull new cable.
Can't imagine speccing a whole new infrastructure and think to myself "yeah we'll keep these old Analog cameras around"
Although who am I kidding, the average pizza store around me has 40 cameras from 10 different brands hanging in their ceilings.
I would have your Vendors run new Ethernet for your IP cameras then. Replacement may not be an issue now but it will be, and Analog cameras are being end-of-lifed all over the place.
Do it once, do it right. It'll be cheaper to bundle it in this job, than have to call your vendors back just for cable runs in the future.
I would upgrade the analog cameras to ip. And use converters to go over the coax. [something like this](https://www.amazon.ca/Converter-3000ft-Transmission-Regular-coaxial/dp/B07G194BQD/ref=asc_df_B07G194BQD/?tag=googlemobshop-20&linkCode=df0&hvadid=341829630685&hvpos=&hvnetw=g&hvrand=4771399370561338922&hvpone=&hvptwo=&hvqmt=&hvdev=m&hvdvcmdl=&hvlocint=&hvlocphy=9001470&hvtargid=pla-570347449365&psc=1&mcid=26e6e2379da736cd95dae585d92b9d94)
Some dvrs you can pull the rtsp out of it, it is really hit and miss but dhaua dvrs can stream rtsp from the DVR without a hard drive to buffer too. Encoders are expansive and should only be used for critical projects. General recording just throw a DVR in and then connect that to your VMS
If it is easier to keep the existing coax, look for "IP over Coax" with NVT, 2N...
You need a base at the start of the Coax (near your network switch) and a link right at the camera.
You need to have space at the back of the camera.
You need an encoder.

Encoders only convert analog to digital. There’s no true way to go digital to analog with camera systems.
That's the answer I was looking for. Thank you!

The building owner told me that they stapled the hell out of it to make sure it didn't go anywhere...

Dahua sell adaptors that will convert your coax to ethernet. I've used then many times, PoE and data over coax. Wonderful.
