Remote camera

Remote camera is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Remote camera rather than just read about it. In short: A remote camera, also known as a trail camera or game camera, is a camera placed by a photographer in areas where the photographer generally cannot be at the camera to snap the shutter. This includes areas with limited access, tight spaces where a person is not allowed, or just another angle so that the photographer can simultaneously take pictures of the same moment from different locations.

Key takeaways

  • Remote camera belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Remote camera to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Remote camera from memory before moving on to harder problems.

Reference excerpt

A remote camera, also known as a trail camera or game camera, is a camera placed by a photographer in areas where the photographer generally cannot be at the camera to snap the shutter. This includes areas with limited access, tight spaces where a person is not allowed, or just another angle so that the photographer can simultaneously take pictures of the same moment from different locations. Remote cameras are most widely used in sports photography. 35 mm digital or film, and medium format cameras are the most common types of cameras that are used.

Uses and practices

Remote cameras are used by photographers to take more pictures from different angles. They are very popular in sports and wildlife photography. Cameras are often placed in angles that a photographer cannot physically be during a shoot. Sport use examples include behind the backboard at a basketball game or overhead in the rafters of an arena during a hockey game. A Baited remote underwater video ("BRUV") is an under-water equivalent.

Placement Remote cameras placed in suspended positions usually are mounted with clamps and arms such as the Bogen Super Clamp and Variable Friction Arm, often referred to as "Magic Arms". The camera and lens are connected to the variable friction arm which is attached to the Super Clamp which in turn is secured to a fixed item such as a basketball post, hand railing, or rafter. Ground plates or tripods are typically used for remote cameras placed on the ground.

Triggering Remote cameras can be fired via hand triggers, sound triggers, radio transmitters (mainly Bluetooth shutters), a built-in self-timer, or a proximity sensor – in which case they are known as camera traps. For remotes that are in close proximity to the photographer, hand or sound triggers can be used. A hand trigger consists of a button or switch that is connected to the camera via a wire that is set to fire the camera's shutter. For remotes that are placed away from the photographer, radio triggering systems such as the Bluetooth shutter button, Pocket Wizards or Flash Wizards are used. A radio trigger consists of a button or switch that is connected to a radio triggering transmitter or transceiver which is set to fire a radio triggering receiver or transceiver that is connected to the camera via a wire that is set to fire the camera's shutter. For rocket launches, including the Space Shuttle, remote cameras are triggered by the sound of the launch.

Game camera

A game camera is a rugged and weather-proof camera designed for extended and unsupervised use outdoors. The images they produce, taken automatically when motion is sensed, are used for game surveillance by hunters, farmers, ranchers and wildlife hobbyists and professionals. These cameras are intended to be strapped on trees or mounted on tripods (or other items), and they are motion-activated. This motion sensor enables the camera to capture images or videos of animals without using up all of its storage space. However, lots of photos of waving plants and moving water can clog up memory cards. These cameras have been instrumental in the rediscovery of multiple species once thought to be extinct or driven out of an area, such as with the black-naped pheasant-pigeon, and fishers in Washington state. They have also used by people endeavouring to take photographs of the non-existent creature Bigfoot (among other cryptids). They can also be helpful for animal loss/rescue in documenting the presence and species of animals, such as determining whether a runaway dog is returning to its home at night or verifying the species actually eating the food left for a stray/feral cat.

Worked examples

Example 1 — a first encounter with Remote camera

Start with the simplest possible case. Write down what Remote camera claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Remote camera before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Remote camera ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Remote camera

In research
Remote camera appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Remote camera in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Remote camera is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cameras, Optical devices, Photography equipment, so understanding it makes those chapters shorter.
In everyday life
Look for Remote camera outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does Remote camera matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Remote camera?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
