Suits Swann 4 & 8-channel DVRs · 12V 2A
12V replacement supply for Swann DVRs.
12V. 2A. Centre positive.
The SR-PSU-12v2A-OEM is a 12V 2A plug-pack for Swann 4- and 8-channel DVRs that came with a 12V 2A adaptor. It plugs straight into the wall and ends in the standard 2.1 mm centre positive barrel plug.
In one sentence: the SR-PSU-12v2A-OEM is a 12V DC, 2A plug-pack power supply with a 2.1 mm centre positive barrel plug and a 100-240V AC input, for Swann 4- and 8-channel DVRs whose original adaptor reads 12V 2A.
Check your old adaptor reads 12V 2A before you order.
Look at the label on the old adaptor or under the DVR. It should read 12V DC, 2A, centre positive, with a round 2.1 mm barrel plug. If it reads 3A or more (many 16-channel DVRs), this supply is not enough. Swann NVRs run on 48V and need a different supply.

When a Swann DVR keeps restarting or will not start.
A tired plug-pack is one of the most common reasons a Swann DVR stops working: no lights, a recorder that reboots, a hard drive that drops out or a picture that freezes. A fresh 12V 2A supply with the same plug is the cheapest thing to rule out first.
The label
12V 2A, centre positive, RCM approved.
Input 100 to 240V AC, 50/60Hz. Output 12V DC, 2A, with the centre positive symbol. The RCM mark shows it is approved for sale in Australia. The unit pictured is model CY-122000; the model number on yours may differ, the rating is the same.
The plug
Standard 2.1 mm barrel plug.
The common CCTV plug: 2.1 mm inside, 5.5 mm outside, centre positive. It fits the 12V socket on the back of Swann DVRs that use this size.

Common questions
Will this fit my Swann DVR?
Yes, if your old adaptor reads 12V DC, 2A, centre positive, with a 2.1 mm barrel plug. That covers most Swann 4- and 8-channel DVRs.
Will it run my 16-channel DVR?
Only if its adaptor reads 12V 2A. Many 16-channel DVRs came with a 3A or larger supply, and on 2A they will restart or drop cameras.
Is it the same plug as my old one?
It is the standard CCTV barrel plug, 2.1 mm inside and 5.5 mm outside, centre positive. Compare it with the close-up above.
Does it work on a Swann NVR?
No. Swann NVRs run on 48V. Use our 48V NVR supplies instead.
Is it approved for Australia?
Yes. The rating label carries the RCM mark, and it has Australian pins so it plugs straight into a power point.
The unit I received has a different model number. Is that right?
Yes. The model on the label can change between batches. What matters is the rating: 12V DC, 2A, centre positive.
Can I power cameras with it?
Yes. It runs any 12V camera or group of cameras drawing 2A or less in total. For four cameras, the version with a 4-way splitter is simpler.
How do I check the supply with a multimeter?
Set the meter to DC volts, plug the supply in, then put the red probe inside the plug and the black probe on the outer sleeve. It should read about 12V.
How do I know my old supply has failed?
No lights on the DVR, a recorder that restarts by itself, a hard drive that drops out or a frozen picture. A new supply is the cheapest thing to rule out first.
What does centre positive mean?
The inside of the plug is +12V and the outer sleeve is ground. Equipment wired the other way round can be damaged, so check the symbol on your old label.
Can I use it outdoors?
No. Keep it indoors and dry. Outdoor cameras need their supply inside or in a weatherproof box.
Can you check my DVR before I order?
Yes. Email a photo of the DVR's underside label and the old adaptor label to [email protected] or call 1300 736 970.

Installation and safety
Mains powered. The plug-pack goes into a standard power point. Do not open the case. A new power point needs a licensed electrician.
Beware of non-compliant supplies. Every mains power supply sold in Australia must carry the RCM mark. Unbranded adaptors from online marketplaces often do not, and some have the wrong polarity or cannot deliver their rated current.
Match the voltage, current and polarity. Only connect it to equipment whose old supply reads 12V DC, 2A or less, centre positive. It cannot power a 48V NVR.
Indoor use. Indoor use only. Keep it dry and give it room to shed heat.
What it does not do. It is not a battery charger and it cannot power a 48V NVR or a 3A DVR.
