7 steps for choosing the right surveillance camera!

Our webshop offers you two help to find the right surveillance camera:

The filter search that you see on the left side of the article overview (see example here).
And the selection wizard, which guides you step by step to the optimal camera for your purposes

For the selection of the optimal video camera, however, some questions should be answered in advance so that you are satisfied with the result and enjoy it for many years. The following points give you a few important clues in your selection:

1. Location

If the camera is mounted outside, whether exposed to direct moisture or rainproof, it should be an IP66 or IP67 classified camera. This ensures that no moisture or moisture penetrates into the housing and destroys the camera. An indoor camera may work outside for some time, but it will inevitably fail after some time.

2. Use by day and by night

It must be clear whether the camera should also record reasonable videos at night and in dark rooms, or whether it should only be used during the day or in constantly lit rooms. So-called IR (or night vision) LEDs emit a light that is not perceived by the human eye, but appears bright for the camera sensor daylight. Since the IR frequency is above the color spectrum, the videos are no longer colored, but black and white.

The built in cameras IR / night vision LEDs have different ranges. This should be considered, for example, when monitoring a plot or a long driveway. The range should be at least 15-20 meters in the outdoor area, in the interior range usually 5-10 meters. Pay attention to the "Night Vision" icon and check the range of the LED in the datasheet of the camera.

3. Power supply of the camera

Today's cameras work with 99% with 12V DC, which means that a power supply is usually used. If there is a power outlet or other power source at the installation site of the surveillance camera, it is sufficient if a data transmission cable is laid up to the camera. (Later will be discussed on the wireless transmission)

If there is no voltage source at the installation site, then there is the possibility of POE supply. POE is called Power Over Ethernet and describes the voltage over the network cable. Here the power supply of the camera is sent together with the data via the network cable. The prerequisite for this is a POE-capable surveillance camera (meanwhile 80% of the offered video cameras are equipped with POE) and a so-called POE switch.

4. Type of transfer

The standard network cable is ideal for the secure transmission of video signals - with the help of network extenders, lengths of more than 800 meters can be achieved! However, it is not possible everywhere to lay an additional cable. For such cases, WLAN cameras offer themselves. Their technology is very reliable, although the range still depends heavily on walls or other obstacles. In case the surveillance camera is installed too far away from the wireless router, it is possible to use wireless repeaters to increase the range.

5. Selection of the lens

One of the most important steps is to select the appropriate lens for the purpose, so that the area to be observed is actually captured by the camera. A large number of cameras already have a so-called "varifocal", ie a variable objective which can cover a large angular range, for example adjustable from 25 to 90 . This is done manually or with a motorized lens that can be remotely controlled from the PC. It should therefore be determined before buying a camera, which angle must be covered. The following link takes you to a lens calculator where you enter the maximum distance and the width (or height). It is also important to specify the camera sensor, which you can find in all technical details. Here you can calculate the right lens with the correct viewing angle.

6. Live picture or recording?

With our plug & play cameras (P2P), you can watch the live video directly on your phone via an app - the setup is done in a few minutes. But what if you want to see what happened 5 minutes or 2 hours ago? You can see on the live video that your front door is open, but you do not know how it came to be or how long she has been standing up. To record the video you need either an SD card in the camera or a connected recorder. With an integrated SD card slot, you can simply insert the SD card (in most cases it is a micro-SD card) and the app will access it. Alternatively, you can connect your camera to a recorder that records all video streams. Due to the higher recording capacity this is the standard solution for professional or commercial video surveillance. Again, the access can be controlled via an app, only that the app does not access the camera, but the recorder.

7. Do not forget the accessories!

For all surveillance cameras, there are different brackets in the accessories (in the webshop you will find the appropriate brackets under the respective cameras): wall, ceiling, mast or corner brackets. With a few exceptions, the proper mount is required to properly place the camera. Some brackets have a so-called "Anschaltkasten" in which all cables can be weatherproof accommodate.

The correct installation location of the camera - lighting conditions and object sizes

1. The biggest enemy: backlight

For the best video quality, the right place for the camera should be carefully selected. Before drilling the holes for the bracket and firmly fixing the cable, check the location of the camera for possible backlighting.

a. Sun History:
If the sun comes into the lens during the day, any camera is overburdened. WDR technology and backlight compensation can compensate for certain types of backlighting, but direct sunlight, in most cases, results in unusable images. Therefore, never try to direct the surveillance camera into the sunlight and consider the course of the sun. Even if you keep the camera looking down, it may happen that the sun goes down in the evening and prevents any observation by the camera. Finding the optimal location may take some patience, but you will end up with a satisfactory result.

b. Car headlights, street lamps and home lighting:
Outdoor spotlights mounted on the house are relatively easy to incorporate into choosing the right camera location. For other backlight sources, such as car headlights, you should first observe the situation to rule out that it comes to direct light.

2. Determination of the area to be monitored

First, determine the area the surveillance camera should cover. For this it is important to determine the correct angle. Keep in mind that the larger the angle, the smaller objects become. Although it covers a large area, it can not properly identify the objects.

A practical tool for determining the correct angle can be found here.

Application: You can read the focal length of the lens above. You search for your location using Google Maps, then press "add camera". The camera can then be rotated and adjusted. After entering the sensor (in most cameras it is 1/3 ") and the resolution you have the result.From the focal length, you are looking for the right camera.If you are not sure whether the correct angle is found, then choose a camera with a variable focal length such as 2.7mm - 12mm, so you can manually set an angle of 28 to 92 Some cameras also have a motorized focus / zoom lens: With these cameras, you set the angle quite comfortably from PC from a.

3. Installation height

For outdoor installation, a minimum height of 3 meters should be used to prevent the camera from being intentionally or unintentionally twisted, covered or damaged. At a lower installation height, it would be easy for burglars to sabotage the camera. The power and data cables should also be unreachable, ideally not or hardly visible. In the interior, this height is often not realize, but there is the height is not as relevant as in the outdoor area.

4. Solid assembly

To ensure that the optimally adjusted surveillance camera observes the set range even years later, the safe and stable mounting of the camera is important. The mounts suitable for the cameras are sturdy and do not twist during a storm. They should be fixed with 4 screws.
