At night, conventional video surveillance cameras do not make it possible to obtain quality images, unless they are supplemented by specific devices. If you do not equip your company with a suitable system, your night surveillance will be limited to the interior and will therefore be much less effective. Most mischief happening at night, read this article to install an effective system that will protect your goods night and day.

Which cameras for night surveillance?

There are two main types of CCTV cameras to protect your activities at night: thermal cameras and infrared cameras.

Thermal cameras:

Thermal video surveillance cameras in Chicago detect the heat of a particularly hot body or object (car, electronic device, etc.). This type of camera is very effective at night since it does not require light. There is however a disadvantage to this type of system. Indeed, these cameras are prone to interference. It is enough that there is a lot of wind, or that an object is placed between your camera and the hot body in question, for the detection to be defective. In addition, you cannot install this type of camera behind a window since the heat will be blocked by it.

Infrared cameras:

Infrared cameras are arguably the most effective for night surveillance. In fact, the infrared radiation produced by possible thieves, for example, is easily detectable since it is emitted in a particular wavelength. A quality IR camera will therefore be little subject to interference. The disadvantage of this type of system is that this type of cameras is quite expensive.

If your budget is tight, you can opt for the following solution: improve your existing system with accessories. The limiting factor being the night light, it suffices that you install a powerful motion detector lamp close to your conventional security camera, to allow it to capture incriminating images in the event of intrusion.

How to create a backup for your NVR or DVR?

It is little known that your NVR or DVR can be backed up to an additional device in the event of theft or loss. Suppose your security camera systems in Chicago recorder are stolen and you are looking for a way to not lose all of your images in the same way. Well you can save your data in real time on a last device, which will be your savior in the event of theft.

What do you need to make video backups on multiple devices?

Both the primary and secondary recorders must be compatible, purchased from the same supplier. If in doubt, contact your supplier for more details.

You need a DVR or NVR as the main recorder

You need an NVR or XVR as a secondary recorder to store live video backup.

You need a reliable wired network to connect the devices.

The secondary recorder must support the same camera specifications as the primary recorder.

You can back up all of your DVRs or NVRs on a local network to another NVR. The video is continuously saved in live mode as the image is filmed. You decide how many cameras you want to back up. If you just want to re-output your NVR for another reason (to display videos on a screen for example, you can replace the secondary NVR with a display screen in the same way. 

How to connect a secondary storage device?

It is easy to connect the two loggers once they are on the same network. Applications with an efficient interface allow you to carry out this manipulation without difficulty.

You can also save a recorder on another website. Before trying, make sure you have a good connection in both locations, also if you have data limits for your connections. Once you are sure of the quality of your connection, just follow the instructions provided by the application or by the instructions for your NVRs.

In any case, installing an additional backup system becomes almost essential. Indeed, thieves have understood that if they steal your NVR, it is your evidence that flies away. A rescue device will allow you to be as effective after the theft of an NVR.

 CCTV cameras for industrial use

Any manufacturing unit has sensitive areas that must be monitored at all times. Access is limited in these areas and certain security procedures must be followed, such that only an authorized person can access these locations inside the manufacturing unit. Areas with high voltage or automated equipment can fall into this category.

Other areas, such as high-value inventory storage areas and areas containing highly sensitive data, such as server rooms, also fall into this category and require constant vigilance. The cameras used to monitor these installations generally manufacture video surveillance cameras or cameras intended to improve the processes.

You need to ask yourself several questions about the security measures taken. Is all appropriate safety procedures followed to the letter? Is the inventory properly locked and only the authorized person has access to it? How often does an authorized person enter the sensitive data area such as the server room? Does a worker remove quarantined items from the red zone? Who has access to the automated equipment section and how often?

Without a surveillance camera installed in your manufacturing plant, you cannot find answers to the above questions. You’re stuck with workers’ reports. And even if your workers provide honest answers, they can’t be as vigilant as a camera. In addition, human memory is very difficult to study compared to the images recorded by a camera. Hiring security personnel is a much more expensive alternative to a surveillance system. And you can explore the facilities from the comfort of your home or any other location via a Smartphone or laptop.

 Delicate infrastructure: flawless monitoring.

Critical infrastructures, such as those producing energy, petroleum, precious materials, telecommunications and other essential infrastructures, require stable and continuous video surveillance 24/7, whatever the light and conditions. weather.

Thermal cameras provide additional detail for detection and standalone CCTV cameras are also required to ensure maximum autonomy. This dual configuration resulted in higher installation, maintenance and operating costs.

Dual lens thermal imaging cameras combining thermal imaging with visual imagery are very useful for this kind of place. Equipped with integrated video analysis functions, the high-quality thermal imager is distinguished by the detection of long-range objects, whatever the harsh atmospheric conditions or totally dark environments. The visual sensor captures high resolution HD video of all moving objects and provides more detail for post-event investigations.

When choosing a video surveillance system for sensitive sites, certain criteria must guide your research to maximize the efficiency of your system. Here are 3 types of protection, linked to different spaces and specific challenges that require fine adaptations of the basic camera systems.

Perimeter protection

1.       Increases physical protection around the perimeter

2.       Reduces the need for human patrols

3.       Effective in dark and dimly lit environments

Applications:

Power stations, petrochemical / petroleum services, ports, prisons, etc.

Boundary protection

1.       Detects intruders from long distances

2.       Automatically detects fires

3.       Alarms for quick response

4.       Effective in difficult weather conditions

 Applications:

Maritime, border patrol, etc.

High value area protection

1.       Detects intruders

2.       No light pollution

3.       Avoids false alarms

Applications:

Car parks, car dealerships, warehouses for precious materials, etc.
