These mobile video/photo recording systems are an amazing piece of technology, and people mostly call them the wildlife cameras. Some people even call them the camera trap due to the fact that they can be easily hidden on trees, on walls, inside bushes, etc. Also, people like these cameras because they can be used for monitoring the wildlife in all kinds of environments: gardens, parks, forests, etc. Wildlife researchers all over the world use these kinds of cameras (see ShootingAuthoritys article here) mostly to observe the nocturnal habits of these animals, which can give out important information about which animals can be found around, and how they are surviving in the wilderness.
However, these things don’t necessarily have to be used in the wilderness; they are great as CCTV units, and will spot any intruder that finds themselves in the zone. This is why many government agencies and law enforcement officers use them as well.
So, what exactly are these digital surveillance trail cameras? Well, they are mobile digital cameras that can be place anywhere, and because they have detection capabilities, it can spot and register any moving object in the area. Whenever anyone moves, the camera activates, and a picture or video is created. During the day, these cameras use the ambient light in order to illuminate the object, and at night, they use two methods of illuminating: flash and infrared.
These cameras also have their own battery supply, and they use C cell batteries or AA batteries; it all depends on the type of the camera. Also, you can get lithium rechargeable batteries for your camera, which will enable you to charge it whenever the need for that arises. Solar panel recharging kit is also an option. It should be said that the standard issue batteries ought to last about one month. Keep in mind that these cameras don’t make any noise, meaning that there will be no additional battery discharge, not will the sound drive the animals away.
The quality of the image on these cameras varies, it can be from 4 megapixels all the way to 12 megapixels. The video that the camera takes has a resolution of 640×480, and is recorded in AVI format. The photographs taken during the day are in full color, while the ones taken at night are black and white if the infrared is being used. The time and date of the taking of the picture will be stamped on the image, allowing you to know exactly when the animal has passed through there.
Now that you know all about the lighting and the images, you also need to learn how to retrieve them from the camera. This is really easy, because all the taken material is being stored on the camera’s SD card. These SD memory cards can have up to 8GB of data space available, and in order to see the images on it, you just need to remove it from the camera, and insert it into a laptop. Also, you can just connect your laptop or desktop computer with the camera (without removing the SD card) via a cable you get with the camera. You can also connect the camera to a TV, and view the images or videos there; and some cameras even allow you to view them on the camera screen.
And finally, there is one decision you have to make before you set out and buy this camera, and that is if you want it in camouflage or black color. If you’ll be using this camera to capture images of wildlife animals and need to hide the camera, you should go with the camouflage. However, if you’ll be using it as a non-hidden camera, than you can take one in black color.
