Video surveillance cameras can be of several kinds. But you’ve probably already known this detail. We have been able to share this vast field in several categories for you and we are trying to build on these important details according to which our security cameras share. Therefore:
By the period in which it works
Daytime / Night Surveillance Cameras (provide both daytime and nighttime images, but in a different way depending on the intensity of the light)
-night surveillance cameras only (rooms that combine at night the black and white image with the infrared)
By resolution and image quality
– Medium-resolution monochrome (white / black) video surveillance cameras (380-420 TV lines)
– High resolution monochrome video surveillance cameras (500 – 600 TV Lines)
-Mare-resolution color video surveillance cameras (<420 TV Lines)
-Meat resolution color video surveillance cameras (420 – 800 TV lines)
-Cameras of high resolution color video surveillance (800 – 2000 TV lines)
Already rooms that reach a measurable resolution in 2000 TV lines can be considered as excellent image quality. Practically, the 2000 TVL resolution of a TVL camera is the equivalent of 2 megapixels for a digital camera. The essential difference is that it will cost a lot less.
By the connectivity mode
– Wired Surveillance Cameras
– wireless surveillance cameras (wireless, rooms to which connection is made by radio waves)
By the level of visibility
-Frame surveillance cameras
Hidden surveillance cameras
By taking the signal
– analog surveillance cameras (classic)
– digital surveillance cameras
Used in a digital surveillance system, digital cameras offer higher resolutions and better images! You will discover with these cameras impressive details of the images that can be magnified and then analyzed. Such a system benefits from progressive scanning and the whole image is captured at the same time at an exceptional quality. In addition, they are not limited in terms of distance, compared to classical analog cameras that can cover somewhere around 300 meters. Network IP cameras have images digitally captured and so they remain for the same, without conversions, without degradation. On the other hand, analog cameras generate an analogue signal, which can then be digitized by an A / D converter for ultimate DSP processing. Attention, digital cameras come with a higher price than analogue ones, but they may also have some interference or installation disadvantages.
By the weather resistance level
-door indoor video surveillance cameras
-Video Outdoor Surveillance Cameras
Which surveillance cameras do we buy?
Surveillance cameras are divided into several categories. We all know that there are indoor cameras (usually dome cameras) and outdoor cameras (cameras that can cover long distances at night and which are more resistant). Besides these types, rooms can also be hidden or false. By installing hidden security cameras in the office or workplace, you can keep an eye on the employees.

This is extremely useful, especially if your business is spinning around money or jewelery. Also, hidden cameras can be used to monitor babies and can help keep babies under surveillance so as to make sure they are safe. False cameras can be used to discourage potential offenders, especially as they are built today, these rooms are hard to differentiate from normal ones. The most sought after are indoor and outdoor cameras that can join a dvr and form an excellent surveillance system. These rooms are different and we’ll explain why. Outdoor video cameras are more weather-resistant cameras and can cope well with temperatures between -30 and 60 degrees celsius. They are also more resilient to the impact with the capricious weather.
Even indoor chambers are not far from the durable term, most of them being antivandal and thus impossible to be destroyed by criminals. But the impact with the external environment can suffer damage, as their obvious destination is the interior. If you purchase outdoor cameras, remember that it is important and that they are perfectly adjustable for the distance you want covered in the location. Today, outdoor cameras can cover distances of 100 meters or even larger, so you can choose from.
