Security camera captures the video of the source. An opened aperture at the front of the camera captures light stream through the camera lens. The light stream is captured by a digital chip that is fitted inside the camera and is converted into the continuous stream of images. The camera records the signal to be transmitted either through cables or wirelessly. The distance between the camera and the object is determined by the camera lens specifications.
Infrared Light Emitting Diodes (IR LEDs) are used as sensing devices in CCTV cameras. The light sensor is used to detect the ambient light level i.e. it detects the brightness of light it receives and transforms it into a numeric value that tells the percentage of brightness.
Due to the digital technology employed in data recording and processing, it is possible to receive sharp images, clear audio and fewer signal interferences from the wireless cameras. This type of camera is often referred to as “IP Camera” (we will talk in more details later)
Phase 1 : Preparation
1) Find out the type of camera you are going to use
The installation process varies according to different types of video surveillance cameras and systems.
Wired vs. wireless security camera, which one to choose? It depends on your specific security needs. Make sure to do your research on the features you would like to have and whether they are applicable to your environment. Get WiFi security cameras, especially battery powered cameras, for flexibility and easier installation, while going for wired PoE IP cameras for more stable network signals.
2) Decide where to install the camera
Knowing where to place your home security cameras determines whether you can maximize the effectiveness of your camera. Know how much angle coverage your camera can cover. Front door, back door and off-street window are the best locations and positions suggested by security experts.
3) Prepare the tools and materials required for smooth installation
Generally, tools needed for installation include screws, anchors, cables, a power adapter or receiver, an electric drill and others. This will ensure that you will have a smooth sailing installing the your system. If you get an all-in-one security camera (system) (Vstarcam highly recommended), screws-kind-of necessary installation materials are usually included in the camera box.
Phase 2 : Installation
1) Check for spots for a good view and stable power source
This is the first important step in self installation of home surveillance systems. Pay attention to the following details when you decide the areas where you’d like to place the camera:
- Mount your camera up high, to make sure it gets a clearer and wider view. Cover as many entries as possible using the least number of cameras to save cost.
- Place the security camera in a place that is out of reach of home intruders and thieves, or naughty kids.
- Avoid pointing your camera directly to a light source. Pointing towards the light source would result in a slight underexposure of videos and images captured.
- Put cameras near a power source. Even a wireless video camera need power supply.
- Place the required mounting bracket for the camera under the eave. This helps protect outdoor security cameras from severe and changing weather.
- It is best not to install a security camera below windows. Or else, the IR reflection may lead to overexposed images and videos (click here to learn more).
- Avoid installing your security cameras to your neighbors’ properties, bathrooms, or places where people shall enjoy a reasonable expectation of privacy.
Drill holes to screw your camera on the wall, ceiling, and other spots you’ve determined for the camera mounting. And then point your camera in the right position and right angle. Always remember to make sure it provides the best motion detection when positioning your security camera.
