Video surveillance cameras can provide another layer of security that a typical security system cannot provide. A security system will, in most cases, deter the intruder, or at least alert the authorities quickly to prevent a major loss of property. If you use video surveillance cameras, you can also detect the intruder while he is ip kamera outside and if he goes in, you can also record his movements in your house.
Why is this helpful?
In many cases, authorities can use the recorded video to identify and arrest suspects. This can lead to the restoration of your property.
You need to choose the right camera for the area you want to protect.
- How far away is the area you want to protect?
- How big is the area you want to protect?
- How detailed is a view you want to see?
- Do you need to see at night?
- Is the area indoors or outdoors?
- Do you need audio?
- Do you want to detect movements?
Bottlenecks
Deciding where to place your video surveillance cameras, remember that you need to analyze where people are walking through the house when trying to cover the inside of your home. Is there a place that everyone has to go through? This is called the choke point because all traffic through your home must be routed through this point. This is a very inexpensive area to place a camera.
Asset protection
There may be certain valuables in your home or in certain rooms that hold more valuables than others. You might want to protect these rooms with a camera.
Selection of video surveillance camera
Fixed or PTZ lens
- A camera can have a fixed view, or it can pan, tilt, and zoom. This means that the camera can be remotely moved left, right, or up and down. You can also zoom in or out. Fixed cameras are far less expensive and a PTZ camera is typically used in an area that is under constant surveillance. Typical costs for a fixed camera range from $200 to $500, while a PTZ camera is in the $2,000 range.
Color or black and white cameras
- That’s actually a no brainer. Color cameras produce much better images than black and white and are not significantly more expensive than black and white.
Wired or wireless
- My preference is always a hardwired camera when possible. After choosing the detection area, you need to decide where to place the camera. There can be multiple locations where the camera can be placed and still achieve your goal. Remember that you need to run cables to the place where the camera is installed. If you have an area that needs coverage and there is only one suitable location for the camera and it would be virtually impossible to get cables to that location, you can choose a wireless camera to get the job done.
Select the lenses
- The lens of the camera is the eye. All images go through the lenses, so everything you see is based on the lenses. There are two basic things to consider, the CCD and the focal length of the camera. The CCD sensor is basically the eye of the camera. The light entering the CCD chip is converted into a video signal using an integrated circuit. The focal length is the distance from the lens to the surface of the CCD sensor.
A wide-angle lens, e.g. B. 3.6mm, gives you a large coverage area, but if your protection area is far away, you may not get the detail you want. Moving down to 16mm gives you more detail but a narrower field of view.
Inside or outside
- If your camera is going to be mounted outdoors, be sure to choose a weatherproof camera, or you can choose a weatherproof housing and install the camera indoors.
- Make sure your cameras are securely mounted. Believe it or not, thieves love to steal cameras, or at least they seem to enjoy destroying them. This is not a problem if they are in fact recorded.
Camera type – covert or conventional
- A covert security camera can be ideal for certain areas. Everyone has heard about nanny cams designed to monitor your kids. They are usually hidden in an area so they go undetected. There is a wide range of covert cameras to suit any home. Because the person being captured ip kamera has no idea they are “on camera,” they won’t try to avoid being captured, allowing you to capture more detail while they’re in your home.
If you want a more detailed image, you can increase your focal length, which will give you better detail, but this will decrease your latitude of coverage. For example, if you are using a 16mm lens and your target distance is 25 feet, your detection range is only 7 1/2 feet. This is much more detailed, but if the subject doesn’t go through your small area, you won’t have an image.
We’ve mentioned the area of coverage in terms of width, but no mention of the area’s height. For most video surveillance cameras, the detection height is about 3/4 of the width. So a 24 foot wide area is 18 feet high. Just multiply by 3/4 to get an idea of the height the camera will cover.
