IP cameras: video surveillance via webcam - tips & tricks
If you want to observe a certain area of your house via webcam and video surveillance, you can do this with an IP camera. We will show you exactly what it is and what you should consider.
Is video surveillance also possible with conventional webcams?
- In theory, you can operate video surveillance with any webcam. All you need is a (cheap) webcam and appropriate software.
- The big disadvantage, however, is that your computer must be switched on permanently so that the monitoring does not stop. There are IP cameras or IP webcams that are not tied to an active computer.
- Suitable software is usually supplied by the camera manufacturer. Third-party software is often very expensive, including the go1984 program.
What are IP cameras and how do they work?
IP cameras are ideal for long-term or permanent video surveillance.
- These are connected to the power on the one hand, and to the Internet via LAN or WLAN on the other. Battery powered models are also available.
- The software is already integrated in the IP webcam so that it does not require a computer.
- The location of the installation is therefore much more flexible. The cables can be laid anywhere inside or outside the house. If your webcam uses WiFi and is battery operated, there is really no limit to the placement of the camera. This only has to be within range of the home radio network.
- The IP camera bears its name for the simple reason that an IP is assigned to it. This is unique and can be entered in a browser from all over the world. So everyone who has knowledge of the IP address has access to the webcam and can configure it and receive live images.
Features and prices of the IP cameras
- Viewing angle: Depending on your needs, you can choose from cameras with a fixed or moving viewing angle. Models with a fixed viewing angle are much cheaper and are available from around 40 euros. Those with a moving perspective cost at least 80 euros. One of the cheapest models is the D-Link DCS-930L for around 45 euros.
- HD transmission: You can also get HD-capable cameras for an additional charge of around 20 euros. The quality of the transmission is thus much better, but also superfluous if you are not concerned with the smallest details.
- Night vision: If you also want to monitor a room or the outside area of your house at night, you need an IP camera that is capable of night vision. These use infrared LEDs so that you get a relatively clear picture, but possible intruders do not discover the camera in the dark. These are available from around 70 euros, like the D-Link DCS-932L. Higher quality cameras also have built-in heating so that the lens does not fog up or the electronics are not damaged in winter.
- Location: The best place to place it depends on your individual needs. If you want to monitor an entire room with a camera with a fixed viewing angle, you should select a corner of the ceiling if possible. If you have a swiveling camera, you can place it in the middle of the ceiling for 360 degree surveillance.
- Software: You can access the camera via the computer's IP address. From there you can usually not only watch live images, but also a live stream. Particularly good cameras often also have sophisticated software with which you can activate motion detection. So you have the possibility to take a picture in advance in the normal state of the room. If the camera records movement in the picture, you can usually be informed by email with a message or even a picture.
- Hide: As angry intruders often take your frustration out at discovered surveillance cameras, you should hide them well. Either choose a place where the camera is not immediately apparent in the overall picture, or build a hiding place for it. For example, a discarded book can be perfectly re-functionalized. Remove the sides and cut a hole for the lens in the cover, this is well camouflaged.
Caution! Comply with the law
- If you are not only constantly observing your property with a camera, but also public space, you must make this clear.
- You must also have the consent of your neighbors if you also monitor parts of their property or property.
- In this case, stairwells, sidewalks, but also parts of the front yard of the neighbor are considered to be public space.
- You can get the appropriate signs in the hardware store for around three euros, or here at Amazon.
