How Do Camera Batteries Work?

Camera batteries are essential for outdoor video capture and photography, for both surveillance and general use. But just how do these sources of power work and what are the eternal functions? Essentially, most batteries contain three basic parts. Electrodes, an electrolyte and a separator. Within every battery are two electrodes, both of which are made of conductive material. When a battery is powering a device like a camera, a series of chemical reactions occur in the electrodes. These are collectively known as oxidation-reduction (redox) reactions. These reactions result in the flow of ions between the anode and the cathode. However, some of the most common batteries in use today are lithium-ion... Read More »

Security Fence Configurations

Security fences are used in many different security infrastructures. While the overall physical structure of the fences are the same, they are often configured differently to suit the varying requirements of different sites. Generally, fencing systems consist of panels which are placed alongside horizontal and vertical wires. Panels are hot dip galvanised followed by a coloured powder coating. The panels and wires are placed in between posts, which span the perimeter of the security site. Posts come with holes pre drilled and tapped to accommodate the panels. This is to allow for an easier installation with minimal tools The Posts come with brackets attached by screws which are tightened with an Allen key.... Read More »

Utilising Security Glass Safely and Securely

Security glass is widely used within home and industrial security systems. It is a visually appealing and functional method of cordoning off and protecting various areas in a building. It is imperative however that the materials used are of a high quality. Many security glass systems are of a high quality as standard. However, the combination of high quality glass and a high quality frame which holds it is what needs to be adhered to. It is sometimes the case that whilst high quality glass is used, the frame or fixtures used to hold it are not at the same level of quality, this leads to issues of compatibility and creates vulnerabilities within the security system. The glass can behave differently... Read More »

Moving From Analogue Tape Recording to Digital

There has been a strong shift from analogue tape recordings, to digital ones used commonly by cameras today. Whilst it may seem like a logical and purely advantageous move to do so, there are certain attributes that analogue recordings still retain. Analogue tape recordings tend to pick up certain fidelities and lighting that clean cut digital recordings smooth out. This can be an advantage or a disadvantage depending on what you are using the recordings for. It may be useful to see lighting arrangements in a more ‘true to life’ analogue format. Or the clean and accurate digital recording may be more useful. Digital recordings are also much more easily edited, allowing for a greater degree... Read More »

Camera Heat Damage, What To Look Out For and How to Avoid it

While cameras are designed to be used in the great outdoors, they are not immune to it. Over time, the temperature, air and humidity of the environment can take its toll. Which is why its important to insure it is protected to the best of its owners ability against the elements. Heat Damage Protecting a camera against heat is a difficult task. You simply cannot control the temperature of the weather. But you can control the heat generated inside the camera. One way to do this is by particularly switching off unnecessary functions. For instance, not using the LCD screen will cause the camera to not use as much electricity, thus generating less heat. Other features such as HD... Read More »
