When Buying a Security Camera
The 10 Main Characteristics to Take into Consideration when Buying a Security Camera.(συναγερμοι σπιτιων)
# 1 - Indoor or Outdoor Surveillance Video Cameras
The primary thing we have to know is if the camera will be introduced inside or outside.
There are cameras that are evidence against downpour, residue and vandalism, which ensures the trustworthiness of the surveillance system.
Consequently on the off chance that we are going to put a camera outwardly it is significant that it be one that incorporates these
attributes.
In the event that we are going to utilize an indoor camera, we can decide on cameras without a waterproof case and by and large without night vision
since there is typically perpetual lighting during the hours that supervision is required.
# 2 - Roof or divider security cameras
In the event that you consider introducing your camera on the rooftop, the most normal is to utilize the Domo model appeared in the picture:
On the off chance that you consider introducing your camera on the divider, the most regular is to utilize the Bullet model appeared in the picture:

# 3 - Security Cameras with Night Vision
To play out a security camera establishment that records 24 hours per day, it is truly conceivable that we need the camera to have the option to
record in any light condition.
In the event that the territory we have to record is constantly lit, we can decide on a surveillance camera without night vision that is less expensive.
In the event that there is no splendor, the utilization of counterfeit infrared lighting with white/dark cameras is prescribed. Then again, you
can utilize day/night shading cameras that change to white/dark in low light circumstances, additionally related to infrared
lighting.
# 4 - Infrared range separation
Clarify that the attributes of the extent of the infrared security cameras are identified with the infrared
go, that is, the separation that the security cameras will most likely catch during the evening relies upon the presentation of their LEDs.
It is entirely expected to discover infrared cameras with LEDs that reach separations of 15m, 30m, 50m and significantly in excess of 50 meters, which isn't
so normal, since this scope of LED extends altogether changes the estimation of the camera.
# 5 - Security camera focal points
Focal points can be separated into 3 huge gatherings:
a) Fixed focal points:
• Wide gap focal points (wide edge) - offers a wide field of view contrasted with the human eye. By cons, the picture will have less
detail. This type of cameras is utilized, for the most part, to watch bigger zones;
• Standard focal points - permit a similar perceivability as the human eye;
• Telephoto focal points - have a limited survey edge, yet enable you to all the more likely recognize objects.
b) Variable optics focal points:(στυτικη δυσλειτουργια)
They can be utilized when it is beyond the realm of imagination to expect to acquire a central length focal point required for a specific application, or when more
adaptability is wanted so as to select the best review point.
c) Slow zoom:
They have a variable central length and are accessible in manual or mechanized adaptations.
# 6 - Connection type for video surveillance camera PoE?
When we talk about how to sustain the video surveillance camera we can refer to two alternatives:
- Power the camera utilizing a similar system link that reaches it.
- Power the camera utilizing an electric transformer.
Right now, most video surveillance cameras have POE power (through similar information link) with which no other power association is
fundamental.
# 7 - WDR and DWDR
The two systems play out the elements of estimation, remuneration and modification of light in the picture.
The difference between them is that in the WDR these capacities are performed through a channel fused in the camera
structure, while in the DWDR it is done carefully on the picture, without the requirement for the channel.
The fuse of DWDR (WDR Digital) in CCTV cameras enabled them to give more and better features without trading off the
cost.
# 8 - High Definition (High Definition = HD)
Picture quality of the IP cameras, its resolution is estimated in MegaPixels and edge rate every second (fps).
The most recent improvement in IP Security Cameras is the 4K or Ultra High Definition Technology. The 4K arrangement offers a resolution
multiple times higher than Full HD (1080p), bringing about sharp and itemized pictures.
# 9 - Resolution Lines (TVL)
It is the estimation of picture resolution in the Analog Cameras. The quantity of TV lines gives us the quality of the pictures
caught by the Camera. By and large, they are much mediocre compared to the pictures produced by IP cameras.
The most widely recognized qualities for resolution are: 420, 480, 550, 600, 700, 800 and 960 TV lines.
Right now the difference in connection to the cost between low, medium and high resolution cameras is low, so we suggest
utilizing cameras that at any rate have a resolution of 600 TVL.
# 10 - The type and quality of the picture catch chip
There is CMOS and CCD technology.
CCD technology is chiefly utilized in simple cameras, while CMOS technology is utilized in new models, including IP cameras.
Remember that the maker of the Image Capture Chip (brand) can mean a great deal of difference in the quality of the video.
You may have uncommon needs in your project and it tends to be hard to tell what is the best solution for you. It is ideal to look for
professional counsel.
