seeseeteevee Posted May 23, 2016 Share Posted May 23, 2016 (edited) Hi there, The previous owners of our house had two dome cameras installed (one at the front and one at the rear) and just left the cables dangling in the loft. I've attached some pics but from what I can tell they are 2 x siamese cables, each having a single video + live + neutral. The live + neutral cables are crimped together so I'm left with the following: - 2 x video connectors - 1 x live wire - 1 x neutral wire I've no idea how to reconnect these other than to assume I need some sort of DVR box for the video connectors but have no idea what to do with the power cables. How do I power the dome cameras? What do I need to do? Thanks in advance.

Rulland Posted May 23, 2016 Share Posted May 23, 2016 A 12v dc power supply unit-2amp output would cover most eventualities. Link to comment https://www.thesecurityinstaller.co.uk/community/topic/40160-reconnect-existing-cctv-cameras/#findComment-446648 Share on other sites More sharing options...

Thanks for the swift response. Do you have a link or something to show me what one of these looks like? I wonder why the previous owners took this with them. Would I need to connect the live + neutral wires to a female DC connector as well in order to connect to the 12v DC power supply unit?

Rulland Posted May 23, 2016 Share Posted May 23, 2016 Look at this on eBay http://www.ebay.co.uk/itm/111829710042 Something like this would do you.-other brands are available.

antinode Posted May 23, 2016 Share Posted May 23, 2016 Have they left the cameras? If so, it would be worth checking their power requirements and video output before you purchase a power supply and DVR. Chances are they're standard analogue 12vdc cams, although 24vac cameras are quite common, as well as HD-SDI, TVI and CVI. If you need a 12vdc PSU, this would do the job fine: https://www.securitywarehouse.co.uk/catalog/genie-2-amp-12v-dc-switch-mode-power-supply-p-3094.html 1 Trade Member Link to comment https://www.thesecurityinstaller.co.uk/community/topic/40160-reconnect-existing-cctv-cameras/#findComment-446651 Share on other sites More sharing options...
seeseeteevee Posted May 23, 2016 Author Share Posted May 23, 2016 The 'domes' are still fitted externally and the cables are running from both of them so I assume the cameras are still there!? I'm struggling to understand exactly how to connect the live + neutral wires to the 12v DC power supply. Do I have to fit some sort of connector on to them like a female DC connector in order to connect to a male DC connector? Thinking one of these would be o.k. https://www.amazon.co.uk/dp/B00AY9RY3S/ref=pd_lpo_sbs_dp_ss_2?pf_rd_p=569136327&pf_rd_s=lpo-top-stripe&pf_rd_t=201&pf_rd_i=B0085SKNTC&pf_rd_m=A3P5ROKL5A1OLE&pf_rd_r=D3AEN9GAPWW8Q95VS8JK Link to comment https://www.thesecurityinstaller.co.uk/community/topic/40160-reconnect-existing-cctv-cameras/#findComment-446654 Share on other sites More sharing options...
seeseeteevee Posted May 23, 2016 Author Share Posted May 23, 2016 Also would I need a separate plug for the cameras and a separate plug for the DVR or is there a way to power the cameras and the PVR together using a single 12v DC supply?

seeseeteevee Posted May 26, 2016 Author Share Posted May 26, 2016 Hey there, So is there anybody on here who can step me through what I need to do? Never done this before so I'd appreciate some help understanding what connections are needed, and how to rig everything up to power the cameras and a DVR. Thanks Link to comment https://www.thesecurityinstaller.co.uk/community/topic/40160-reconnect-existing-cctv-cameras/#findComment-446778 Share on other sites More sharing options...
al-yeti Posted May 26, 2016 Share Posted May 26, 2016 Get a digital volt meter unless you intend to guess , because you have allot info above , have you tried any yet? There's no garuntee there's no faults present on the existing wiring unless you know how to test the cables Link to comment https://www.thesecurityinstaller.co.uk/community/topic/40160-reconnect-existing-cctv-cameras/#findComment-446779 Share on other sites More sharing options...
