Hi I have a swann system dvr4-3260 and I have 2 cameras working on it and I was wondering if this would work on my system.

Asked by: Maggie
Unfortunately, we are unable to guarantee compatibility with this, I would consider contacting Swann directly to discuss this.

Is this a permanent recording camera and also is it compatible with the Swann Heat-Sensing 8 Channel 1TB CCTV Kit?

Asked by: Spacehopper
The DVR unit determines if the camera records all the time or only when motion occurs. This camera would be unsuitable for the 4575 series (heat sense) examples of suitable cameras would be http://www.maplin.co.uk/p/swann-pro-1080msb-heat-sensing-1080p-hd-camera-twin-pack-a69xj http://www.maplin.co.uk/p/swann-pro-h856-1080p-dome-camera-twin-pack-a77wg
