this is a used preowned astak model 707 DC12V 2.4GHz security camera receiver.this is a being sold as is parts and repair only and untested.it does power on as intended but that is as far as i can go with it.i do have a cord for this unit but it is not the correct one,but it does work for it.anyway there is some wear on this receiver.there are some scuffs,scratches and some small nicks and dings as well.these defects can be found throughout the receiver.i do not believe it is anything abusive just general use wear.the exception to this maybe being a brighter scuff on the bottom side of the receiver,i will try to capture that in the pictures.the power supply that comes with the unit is a linksys model no. D12-50-A .there is some dust and general use wear on the plug in and cord.a few scuffs and scratches are also apparent.it is quite possible that this unit works but i could not test it myself fully and i do not want to make a false claim.thank you for looking at this listing.
