4 Tricks You Didn’t Know Your Security Camera


We all know we should probably have a home Security Camera (https://www.megri.com/) to keep our home safe and intruders at bay. In fact, according to IHS Markit, there were 245 million professionally installed video surveillance cameras active and operational globally in 2014 alone. But if you’re on the fence about investing in a security camera system, or wish you could get a little more out of it for your money, consider all of the other things your security camera can do that you probably never thought much about. From creating home movies to solving a good mystery, here are some cool tricks.


Create time-lapse videos: There are fun things your security system can do besides protecting your home. For starters, try creating your own time-lapse videos with the help of your security camera footage. Upload your video to an editing tool, increase the speed of your video as desired, slow down, slice and cut in new images or videos and download. Then share your video with family members or neighbours to show off your new skills with the help of your security camera.


Check the real-time weather: Ever wanted to know if it was snowing because you’re worried about the car you left in the driveway? Curious how hard it’s raining and if it’s impacting your garden area? Sure, you can check the weather and read the stats, but it won’t tell you for 100 per cent certainty what’s going on and how it’s impacting your property. Instead, you can monitor the real-time weather from anywhere. Log into your security camera system’s video, watch what’s going on and give your neighbour a call to ask if they’ll grab your spare keys and move your car in the garage.


Record family moments: Hosting a family reunion outdoors is a fun experience, but it’s hard to stay in the moment and capture the moment in real-time. Instead of hiding behind the video camera all day, just dig into your home security camera system after your big bash. Download the footage, take screenshots to frame or create a video and share. Better yet, throw another party to view the footage together. It’s a great excuse to get the family together all over again.

Solve a good mystery: What’s going on at your front door or lawn lately? Are you wondering why the rocking chair is always moved a few feet to the left? Curious who is snagging your morning paper every day of the week? Instead of launching a time-consuming stakeout, go through your security footage instead. Maybe the neighbourhood kids are sitting on your porch when it rains while waiting for the bus. And perhaps the guy next door isn’t being so honest about not having any idea who is taking your paper. Just show him the footage and watch him scramble for an excuse. At least you know you’ll have your missing newspaper problem solved.

How does a camera work?

Since that first camera did not capture very much light, it actually took eight hours to take a single photograph. The image was also quite blurry. So how are we able to take sharp images in milliseconds today? A camera lens.

While light bounces off of objects, it can also pass through objects — but, when it does, it can actually change direction. A camera lens takes all the light rays bouncing around and uses glass to redirect them to a single point, creating a sharp image.

When all of those light rays meet back together on a digital camera sensor or a piece of film, they create a sharp image. If the light doesn’t meet at the right point, the image will look blurry or out-of-focus. A lens’s focusing system moves the glass piece closer or farther from the sensor or film, allowing the photographer to adjust the lens so that the object is sharp.

Distance also plays a role in how camera lenses are able to zoom in. When the front piece of glass moves farther away from the camera sensor, objects become closer. Focal length is the measurement of the distance between where the light rays first hit the lens and where they reach the camera sensor. For example, on a lens with a 300mm focal length, the light takes 300 mm to be directed back into a sharp point on the camera sensor. A 300mm lens is considered a telephoto, or a lens that’s able to bring far objects close.

A camera is an optical instrument that captures a visual image. At a basic level, cameras consist of sealed boxes, with a small hole that allows light through to capture an image on a light-sensitive surface. Cameras have various mechanisms to control how the light falls onto the light-sensitive surface.
