How many types of CCTV cameras are there?


  1. Bullet Type Cameras are designed for capturing images in a fixed area. These cameras are recognized by their thin and cylindrical design. There are also classifications of Ultra Bullet distinguished by their smaller size and cheaper price.
  2. Dome Cameras, named after the shape of their housing are designed for in-store installations. It works in two ways as it is unobtrusive but visible, thus, it warns people that the area is protected by a CCTV network and gives comfort to its clients for its security.
  3. Discreet CCTVs are cameras in disguise, they could look like a fan or any other thing that would not seem suspicious in the area.
  4. Infrared Cameras are designed for evening lookouts. It captures images with the help of its infrared lighting surrounding its lens.
  5. Day/Night Types are used for 24/7 installation, these cameras compensate light conditions with its wide dynamic range to function in glare, direct sunlight, reflections and strong backlight.
  6. Varifocal Cameras are designed to allow zooming in and out without losing focus on the image.
  7. Network Cameras allow transmission of images through the internet with controlled bandwidth.
  8. Wireless cameras are cameras that may or may not be connected to the internet. These cameras use signalling devices to transmit images from camera to viewing area.
  9. PTZ Cameras or pan-tilt-zoom are cameras that can moved. There are variations of these cameras that are programmable and are manually controllable. This allows viewers to have more freedom and control on viewing things.
  10. High definition cameras are often used in casinos or high risk establishment. With its high resolution lens, capturing images are possible giving viewers a finer detail on taken images.


What’s the point of fake CCTV cameras?

It is to make people think that they are being monitored while not actually recording anything. Number of crimes substantially go down in the presence of a surveillance camera which is visible to people. This is not to say that people won’t commit crimes at all in its presence.

When you show people that you carry a revolver with you, they will be careful not to pick a fight with you whether or not there are bullets in it. Although,some people would still try to hurt you in certain scenarios.

This scenario is pretty much the same.


Differences in Camera Resolutions

The resolution of a camera is one of the most critical and desired features. The resolution of a camera is crucial for generating usable images capable of identifying individuals and license plates. The ability to provide a much higher resolution than a traditional analog camera has long been a benefit of using an IP camera over analog cameras, though HD analog solutions are now closing the gap.

Resolution is measured in pixels and abbreviated to Megapixels or MP. One megapixel (1MP) is equivalent to one million pixels.
We now prefer to start all of our conversations at 4MP, thanks to technological advances and subsequent price drops – the Hikvision 4MP R6 family of cameras, for example, is now priced cheaper than a 2MP camera would have cost you a few years ago.

The majority of the time, a higher resolution is preferable. There are a few drawbacks, though: a higher resolution video stream, for example, would require more storage and bandwidth headroom, and low-light output will usually suffer as a result. However, as the resolution has increased, the image quality improves dramatically; a face or number plate may have a higher number of pixels-per-foot, allowing better information to be picked out and recognized.

Below is a list of common IP camera resolutions and their respective pixel Width x Height measurements based on a Hikvision camera. You may be familiar with certain resolutions when you consider your TV or PC monitors.

1MP = 1280 x 720 (AKA 720)
1.3MP = 1280 x 1024
2MP = 1920 x 1080 (AKA 1080)
3MP = 2048 x 1536
4MP = 2688 x 1520
6MP = 3072 x 2048
8MP = 3840 x 2160 (AKA 4K / UHD)

Many of our customers aren’t aware that a 4MP camera has significantly more pixels (more than double) than the 1080p TV and monitor they’re used to. This is exacerbated by the fact that most cameras can automatically resize their stream display to fit on a monitor that doesn’t support the camera’s resolution – for example, you wouldn’t be able to see the whole 2688 x 1520 stream on a monitor that only supports 1920 x 1080. Viewing the stream at its native resolution is almost always possible, but you’ll have to scroll around to see the whole picture because some of it will be off-screen. When zooming in on a faraway object of interest, the true advantage becomes apparent.


1MP = Green
2MP = Cyan
3MP = Blue
4MP = Yellow
8MP = Red​


When buying an IP camera, it’s also important to think about the focal length you’ll need. We created a similar article where you can learn more about focal lengths and the different viewing angles they provide.

It’s impossible to cover a large angle with a low resolution because an object of interest actually doesn’t have enough pixels to have functional identification (quite common on fisheye cameras, unfortunately). Picking a high-resolution camera to cover just the region you need is the best bet. This will show the largest and most accurate picture of what you’re looking at on your phone. A YouTube video illustrating the differences in focal lengths was recently released.


Previously, anything with a resolution greater than 0.4MP was only available from IP cameras. However, as previously described, technological advances have enabled the development of HD analog cameras with resolutions of up to 5MP (and, apparently, soon 4K!). Hikvision’s Turbo HD analog cameras, which use HD-TVI technology, are among our favorites; you can see them on our site.

With 4K expected to replace 1080p as the standard for TV and PC monitors in the coming years, it appears that 4K surveillance will become even more widespread in the coming years.
