Fixed surveillance cameras are mostly used in most locations, but some PTZ mobile surveillance systems need to provide the number of surveillance cameras on the site and reduce the system to a limited number of mobile surveillance cameras, of course, the prices of PTZ mobile surveillance cameras are very high for fixed cameras and have all the features of optical and digital zoom and are capable of displaying a high-resolution image of distances exceeding 150 meters with night vision and 500 meters by day.
Fixed and variable observation lenses
Surveillance camera lenses, some of which are fixed, cannot be adjusted, but are carefully selected to suit the installation site, some of which can be changed manually to fit the required image dimensions VARIFOCAL LENS, and some of which are variable and can be adjusted automatically motorized LENS through computers, projectors, recording and mobile phones.
Possibilities of image enhancement, brightness adjustment and lighting balance
Currently, by 2018, surveillance cameras that do not have these characteristics, such as AGC | AWB | BLC | DNR, are not accepted, which are properties that make surveillance cameras capable of balancing image signals, processing noise and interference, determining color ratios, adjusting brightness and glare, and there are other specifications that offer greater possibilities, but they are used at the time of need due to their high cost, such as WDR | AI, which makes the camera able to take a picture in the darkest conditions, such as bloody darkness or when the light is directly on the camera lens.
In terms of installation location
Wired home surveillance cameras:
You do not need additional capabilities and features, but you need a thorough test that serves the purposes of home monitoring and adjusting the Settings well for ease of use of the system and ensuring its uninterrupted operation.
