3 Megapixel IP Dome Security Camera

In this video I’m going to show you our brand new vandal dome model number IPVD-ELMPIR.

This is a vandal dome 3 megapixel camera that just arrived.  It’s very good, it has an amazing picture and I’m going to show you how to open it and show you what you’ll see inside the camera when you do open it.

First you will notice that the camera has three screws and it has an Allen key that is provided in the package so you just basically unscrew the three screws right here.

This comes off:

and here is the inside of the camera:

It has the IRs, the sensor, it has a lens, a 4.5 to 10mm varifocal lens.  It has a heater/blower inside and it is capable of recording directly at the camera.  It has a slot for a micro SD card up to 32 gigs and the SD card will look something like this:

You can just insert it there and put it on your network, configure some of the features and you will be good to go in no time.   The camera has a pigtail which includes the RJ435 connecter or the Ethernet port where you are going to connect it into your router.

It is capable of PoE power over the Ethernet, meaning that you don’t need a power supply so you can just power on the camera if you have a PoE switch.  You can also plug it in to a regular 12 VDC or 24VAC power adaptor, i. e. it’s a dual voltage camera.  This camera is capable of having audio recording but you have to put a microphone in.  It’s able to plug into a regular DVR through the BNC but you won’t really get the 3 megapixel resolution.  And this pigtail over here this connector has more features this is the other end of the cable you can connect an RS45,

you can connect alarms, like you know it has alarm inputs and outputs.  Also it comes with the pattern for installation if you want to mount it.  It’s a very, very good camera good quality, vandal proof, its capable of recording at 3 megapixel or 1080p which is 2 megapixel.  You can use this camera on our brand new Hybrid DVR.  Our Hybrid DVR is capable of handling this camera up to 1080 p resolution.  This camera is a tri-ax camera meaning it can move in three different planes.  I will be making some more videos showing the configurations and how to plug it into the network and how to configure it.  I hope this has been informative for you and I would like to thank you for viewing.

Dome Security Camera

The dome security camera is one of the most popular types of digital video security camera in use today.  Thanks to modern technological advances a lot of electronic power can be packaged inside a small 3.5 inch diameter dome camera.  Not only are they small and powerful, but the average dome security camera is light weight as well (in most cases weighing just under one pound), which makes it easy to mount just about anywhere.

Today, there are three standard types of digital video camera based on shape; the box type, bullet type, and dome security camera.  How, what, and where the camera is used usually dictates the type, although user preference is also a factor.

Dome cameras originated from their older analog ancestors.  These cameras were often big and bulky and required a great deal more depth than today’s dome security camera.  Often, the older cameras were actually box cameras placed behind a wall or ceiling with the body of the camera extending into the wall space ith just the lens extending through a pre-cut opening.   A glass dome was then fixed over the lens to make it more aesthetically pleasing.  Blackened glass or two-way mirror glass was often used to conceal the lens, so that potential shoplifters, intruders, etc. would not know in what direction the lens was aimed.

Current dome security cameras are nothing like what is described in the previous paragraph.  Considering that the main components of a digital video camera are the lens, the sensor chip, and the Integrated Circuit (IC) electronics the largest part of the camera is often the lens which on the average is about 3.6mm in diameter.

A digital video dome security camera is a compact, highly sophisticated electronic piece of equipment.   The sole purpose of the camera is to transfer light images into electronic images that can be seen on an electronic display device such as a monitor.

It does this by first using a lens to focus the field of view onto a tiny sensor chip.  These chips range from 1/3 inch to about 1/2 inch square.  One of two different sensor ships is used.  Although the chips go about the process differently, both yield the same result; transferring light into electronic impulses that can be measured (and therefore used to create an electronic image).

The sensor chips are either a Charged Coupled Device or CCD or a Complementary Metal Oxide Semiconductor or CMOS.  After the sensor chip converts the light image into an electronic impulse, the IC chips take over processing and digitizing the electronic information and passing it along to the Digital Video Recorder or DVR.

There are several types of dome security cameras based on how they function or where they are intended to be used.  Dome security cameras can be classified as indoor, outdoor, or indoor/outdoor types although most outdoor types today are the combination indoor/outdoor.  Indoor dome cameras are intended to be used inside, under protective cover from the weather and other elements.

Outdoor dome security cameras are protected by an outer shell or case that prevents water, snow, hail, or other damage to the camera itself.   These cameras are often rated according to the International Electrotechnical Commission’s (IEC’s) Ingress Protection or IP standard.   An IP rating of IP55 or higher is usually considered good.

Dome security cameras are usually flush mounted on a ceiling or wall, but may be mounted on special mounts that can range from peduncle type to horizontal extensions.  They require very little surface area for mounting, and can usually be mounted easily using from two to four screws.  The video transmission cable and the power supply cable usually attach from the underside of the mount or there are extensions exiting from under the mount such that the wires remain hidden and protected by the structure the camera is mounted on.

Dome security cameras may also work in InfraRed (IR) modes and the IR Light Emitting Diodes or LEDs are normally clustered right around the camera lens.   This provides directed IR illumination in the exact field of vision of the camera lens.

Security Camera King offers a wide selection of indoor and outdoor (as well as indoor/outdoor) dome security cameras.  Our cameras are of the highest quality and offer the best performance at the most economical price in the industry.
