military grade security cameras

Military-grade security cameras are increasingly being used to increase security in both commercial and office spaces. If you're looking to invest in a surveillance system, there are a few things you should know before making a decision you'll be happy with. The more informed you are on this subject, the better you will be able to make a choice that suits your needs and the space you want to monitor. Many people only focus on a brand that is appreciated by the majority of users without considering other essential elements. Therefore, see some helpful information you need to know about any surveillance system.


What Are the Components of a Surveillance System?

There are several components to a surveillance system, but basically, we are talking about DVRs and surveillance cameras. The DVR or Digital Video Recorder is the "brain" of the surveillance system, the element to which all components are connected. A DVR has several functions: it processes the signal from the cameras, relates to the Internet to provide control over the images, detects motion, and stores video recordings. There are several camera models, depending on your needs but also on the space that needs monitoring (indoor or outdoor cameras). Other components of a surveillance system are the power supply or batteries, the cables, and the monitor.


What Are the Advantages of Military-Grade Security Cameras?

Often, military-grade security cameras are more effective than the presence of a security guard – criminals can be scared off by video cameras because they know that they can be recorded and identified later much more quickly. That is the most significant advantage of a surveillance system. Criminals are intimidated and kept away from valuables, whether it's a personal home, an office space, or an institution's premises. A surveillance system you see on a friend might not be suitable for your needs. When choosing surveillance cameras, you must consider:


  • Resolution.
  • Type of lens.
  • Type of camera (indoor/outdoor).
  • Size of the space to be monitored.



Additional functions such as infrared, motion sensors, video recording and storage, and sound recording are essential, too. The better you choose a surveillance system, the more advantages you will enjoy. But no classic surveillance system will let you down. If you need peace of mind while you go on holidays or delegations, install a surveillance system. You will have control over the images captured by the cameras wherever you are; you will be able to intervene much faster if a criminal decides to violate a prohibited perimeter, and, of course, you will have proof of the crime captured by the surveillance cameras.


Poor-Quality Video Cable and Video Connectors

The outcome? Waves, stripes, and fleas in the image day and night; poorer images than the military-grade security cameras could provide if quality connectors were used. To save money exactly when you have to buy the cable and connectors for the system. Lack of knowledge is the main culprit here. Not knowing the consequences of using a low-quality cable, the cheapest possible cable is often chosen in the desire to save money. The person doing the assembly may think it doesn't matter which cable and plugs are used; perhaps he doesn't care; in any case, it's a significant and widespread problem.


Video systems have evolved a lot in recent years. The cheapest and most accessible military-grade security cameras start with a 1-megapixel HD resolution. There are now analog systems of very high resolution, with many megapixels, therefore of high fidelity. These high-resolution video signals are much more vulnerable to lose and interference than the video signals from old cameras with 700 TV lines. Imagine that you have to transport a bucket full of water in a car. The fuller the bucket, the greater the chances of losing water on the road due to potholes, bends, etc.


A high-resolution video signal is like a full bucket, a low-resolution video signal is like an emptier bucket, and the potholes and curves are the losses along the route. If you use a bad quality cable with bad quality connectors, you will have significant losses, so from all the high resolution for which you paid a lot of money, you are left with what remains after the losses suffered. In addition, out of the desire to make sales, cable traders have brought on the market very cheap and nasty variants of cable and connectors.

The Length of the Camera Cable Matters!

The video signal transmitted by the military-grade security cameras uses a tiny current. For this small current, it is essential to have at our disposal a conductor with the highest possible efficiency. The entire video route, from the video jack used to the camera, going through the physical contact between the jack and the cable, through the cable, to the DVR jack, must offer the most efficient information transfer, with as little loss as possible. The solution? Pay attention to the material used for the conductive material in the cables and connectors.


Exposed Wires Surveillance Camera and Condensation Camera

Almost all modern cameras are built with a decent standard in terms of protection against moisture and dust. Of course, there are exceptions for no-name products, sold at prices too low to justify any trace of quality. A camera housing is usually well enough built against moisture and dust, but not the video and power connectors of the camera. Those connectors, if not adequately protected and mounted, will oxidize or conduct water inside the chamber. It is compromised once a small amount of water has entered the camera housing. Condensation will appear on the lens, and the camera will be useless.


Sure, it can be undone, dried, or resealed, but it is best to prevent it. The first and most common problem is the oxidation of the video and power connectors. How does oxidation of connectors occur? Very simple. They are left in the air by an unskilled installer or willing to be called for periodic maintenance. Any military-grade security cameras mounted externally, if it does not come from the factory with a special grommet designed to protect the connectors (some cameras have something like this, usually the most expensive ones), needs an apparent box with a cover to mask and protect video and power connections.
