I have a front door camera and would like to feed the images to 4 screens around the house and to DVR. I thought that there would be a adapter that can do this, but at the moment I can only find max a 4 way splitter . I have found powered amps that can split more but these are powered. Is there a reason it wouldn't be possible to split the signal 6 ways? Any suggestion of a way to do this? Can I just use daisychained 2 splitter

The driver may not have the signal power to feed that many receivers, signal quality may also be seriously effected.

It would be better to run back to the DVR and then split the video feed from that to the TVs. The bonus being when you add more cameras you won’t need to split each camera you just need to run to DVR
 
How does the DVR output it to 6 screens? I thought there is only one output port and the option are how many of the input signals to show on there.

The big question is what camera format ( cvbs / TVI / CVI / ip ect ) is at the front door ? Not all splitters support the above formats !

If you've using composite video this ought to work https://www.amazon.co.uk/Milkee-Distribution-Amplifier-Monitoring-Broadcast-1-8-out/dp/B06ZZRLJ48

EDIT Aah, you wanted a passive splitter. Not going to happen- if you do daisychain a load of passive splitters you'll have rubbish signal at each output. That jobbie above only needs 9v so it could be a few metres from nearest 13A socket

Current setup just had them connected together. I haven't yet opened the tape to see exactly what they did. Can you just twist around BNC cables to get a signal?
 
In general passively splitting composite video isn't a great idea, you will likely get some signal through but it is likely to be marred by signal reflections. Especially if the cable runs are long.

If you must split then an active splitter is the way to go.

Some proffesional CCTV monitors have a "hi-z" switch, this disables the termination resistors in the monitor allowing a passive T peice to be used without screwing up the impedance, but for best results the connection from the T piece to the HI-Z monitor must be as short as possible (ideally the T peice is directly attatched to the back of the monitor).

edit: oops said the opposite of what I intended to say, edited to fix.

Ok, I opened the tape and all it was was 4 rg59 stripped and twisted together and screws info a connector block. I stripped the new one and twisted it together and it works.I may be losing quality but it isn't noticable to me and it works... Most definitely not the correct way. Thanks for all input.
