Do Not Use Aftermarket Power Supplies With Your New Security Camera

So if you are wondering about the picture, you should. No, we are not trying to call anyone out, but we consider this to be a preventative measure or a technical support lesson for
security cameras that might not work. If you have experienced an issue with a brand new security camera and you are wondering why it may be damaged, then this is directly related to two problems. One problem that seeming to become more and more popular is hooking up the wrong power supply to your security camera. Now we sell all of our security cameras with the correct power supplies. We double check and triple check to make sure the power supplies match up correctly with cameras amperage requirement. Even still we will have some people go out to Radio Shack and purchase additional power supplies. If you are going to do that then make sure you have the right amperage. For most security dealers on the web, they list all the specs on the products. You can find the camera’s amperage require it will tell you what it needs to run. Cameras with small amperage requirements are small domes, bullets, and hidden security cameras. Infrared security cameras will have a higher amount or amperage requirements. That is due to the infrared LED bulbs that are onboard. The infrared bulbs will require a lot more amperage than any regular color camera. This can pose a problem, because if you have a power supply that is the wrong amperage you can blow up the camera, burn out the IR lights, or short the circuitry of the security camera. So having the wrong power supply is having the wrong power supply. If your camera is dead and you do not know why, then check the power adapter you have and check the spec sheet that came with your camera and see if your power supply has the right amount required amperage. You want to be very suspicious if you have a security camera with a lot of infrared lights, because you do want to make sure the power supply is at least 1amp. If you do not have a security camera below 12 infrared lights or a hi-resolution color security then half an amp should work. If you are unsure, call and speak to a tech or join our forum and ask a question.


PTC Enabled Power Supply Boxes Are The Best

PTC Power Supply Box
















PTC technology used in CCTV power supply boxes are used to manage the amount current that passes through each channel of power. PTC itself is an over current-protector and is connected in series with the load that is to be protected. During normal operating conditions, the PTC remains in its low resistance state resulting in negligible attenuation to current flow. When a short circuit or over current condition occurs, the PTC will switch into its high resistance state thereby limiting the current flow in the circuit to a point well below the normal operating level. Once the current condition (fault condition) is removed, the PTC will return to it’s low resistance self and allow the current to run normal. This technology works great in the field of CCTV, because you don’t have to worry about overloads crashing your security cameras. Or better yet you can save your security cameras from shortages, spikes and surges. Obliviously if lighting strikes the camera, then it is over, but if lighting strikes some where else then you can bet on this device not letting current
