Thermal Image Security Cameras

Comments Disabled

Thermal imaging security cameras are getting immense popularity these days due to several reasons. They render infra-red radiations that help in detecting the things invisible to the naked eye. These cameras are commonly known as FLIR (forward looking Infra-red) and possess many uses in business as well as home area. They have been in use for more than a decade in a variety of ways that include night security, military areas, tracking criminals in night time, R&D, Maritime, Intelligent transportation systems, Gas detection, cores and components and many more.

The viewing distance of thermal Imaging Security Cameras is limited to the range of Infra-red illuminator. These cameras are capable of making image from the heat energy, giving you 24*7 images without lights. They have the power of thermal energy that penetrates atmospheric obscurants more perfectly than in the daylight. The topmost benefit of thermal imaging security cameras is that they are capable of making an image through smoke, fog, dust, night time, rain, bad weather, etc.

How Do Camera Batteries Work?

Comments Disabled

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 batteries, these power most consumer electronic devices. These batteries typically contain a carbon anode, a cathode made of lithium cobalt dioxide and an electrolyte containing a lithium salt in an organic solvent.

Security Fence Configurations

Comments Disabled

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. The clips grab both panels in one go removing the need for a bracing wire at the top or bottom of the panel.

Gates are also constructed in a similar way and fit in conjunction with the fencing panels.

Utilising Security Glass Safely and Securely

Comments Disabled

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 in different framing systems. So it is recommended that high performance glazing is combined with high quality framing systems to attain a high level of protection.

A high quality frame and glass is a far safer alternative to the cheaper variations. Allowing for a secure and reliable system.

Moving From Analogue Tape Recording to Digital

Comments Disabled

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 of image enhancement.

For the purposes of surveillance, digital recordings are much more usable. The ability to easily store many recordings, as well as their transferability between computers makes them much more suited for current security standards.
