A flashing green light on a Swann 960H Pro Series security camera system can indicate a few different things, depending on the specific model and configuration of your system. Some possible causes of a flashing green light include:

1. The camera is in setup mode: When a camera is first powered on, it may flash a green light to indicate that it is in setup mode and ready to be configured.
2. The camera is in standby mode: When the camera is not actively recording, it may flash a green light to indicate that it is in standby mode and ready to start recording.
3. The camera is recording: Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is recording.
4. The camera is low on power: Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is low on power.
5. The camera is malfunctioning : Some models of the Swann 960H Pro Series security camera system have a green light that flashes when the camera is malfunctioning.

Swann SW214-SCC


back of box shows, 8 to 12vdc, 300mA min.
i'd buy 12vdc 1amp pack, so common it cries to be bought.

why not ask maker, or get the manual
here
https://www.swann.com/au/

seems it's super old and poor resolution that nobody wants to own, today.
but give them a try. or google it.
the manual is lame,

https://www.manualslib.com/manual/1406198/Swann-Sw214-Odc.html?page=2#manual

it only works with TV or systems with RCA composite video input jacks. (the manual mentions VCR, what joke that is)
my home theater has that jack as does my TV
and so does my fine CAMERA NVR server.
this camera does 510 x 492 resolution and is pathetic.

vastly better today is this.

I have many of those, and 1080P is real real nice.

Your cameras might be in PAL mode, go into system settings and change to NTSC setting.

Same problem with mine. Sent it back to shop, now testing the second one.
I have emailed Swann regarding this problem and all they say is "send it back" to point of purchase.
