PTZ mobile surveillance cameras: works in all directions 360 degrees from right to left and 90 degrees from top to bottom.
Fixed lens surveillance cameras: one of the most famous is the dome diameter surveillance camera, where it is directed to shoot in a certain direction and the angle of shooting is not clear to people.
Solar surveillance cameras: they are used in areas that are not equipped with a power source from the regular electricity network.
Long-distance wireless surveillance cameras: they have a high ability to transmit the video signal to a distance of 1 to 10 kilometers and with superior quality between the camera and the recording device.Descriptions of AHD surveillance cameras and their features
Ahd-HD technology is characterized by using the same copper wires used to connect the TV signal, and this technology is considered a qualitative leap in the field of surveillance systems
The most important features of AHD HD technology used in surveillance cameras
It is also characterized by this technology that it supports Lo B RET, that is, it gives room for image transmission with the same quality and up to 500 meters, and not as in the previous analog technology, it should be noted that this camera technology does not work on regular DVR, and you must get a DVD that supports HD (AHD DVR), which is available in several technologies, including B, analog and HD cameras at the same time, that is, they can be installed together
AHD CCTV cameras are connected to the dvr using an RG59 or RG6 coax cable
High-resolution video transmission through coax cable from surveillance cameras to digital recording devices
One of the advantages of AHD over HD cameras is that the RG59 coax cable can be operated over long distances without losing video quality
