Types of Hikvision IP cameras
Hikvision IP cameras with PoE also called network cameras, carry the signal digitally between the camera and the recorder ( Hikvision NVR) much like linking your office computers and mobile devices to your wifi at home whereas HikvisionDVRs ( digital video recorders) only record the signal in digital format. This can be compared to the digital TV switchover which ended the "snowy" or ghosting pictures. The same applies to digital CCTV systems. Any CCTV product attached to the Hikvision NVR has to be "network " or "IP" ( internet protocol) compatible.
You can tell the difference between a Hikvision IP camera and analogue CCTV camera from the connectors. An IP camera has RJ45 Ethernet connectors also known as network or ethernet connectors as shown in the picture below.
Nearly all of our Hikvision NVRs have built-in PoE ( power over ethernet ) which means there is no need to buy a power supply to power the cameras as its built into the NVRs Only one cable is needed between the IP camera and the NVR, this cable is called CAT5 or network/ethernet cable as shown in the picture below. This cable can also carry sound and other control signals and also have additional devices connected to the IP cameras such as control relays for switching other devices.
Cable used for IP/network cameras
The Hikvision IP cameras can also be connected to the Hikvision NVR using a power line plug or a HomePlug as its sometimes called. This is very useful when you have an area where it's difficult or impossible to cable such as a garage next to your home. You can buy a home plug kit and one plug into your mains socket near your router and the other in the mains socket in the garage. You will also need a power supply to power the camera which would connect into the homepage.
HomePlug can be used in place of cables
For long distances or for commercial buildings which have 3 phase electricity and cant use a HomePlug, there is the option of using wifi or wireless transmitters. These can be up to 5km apart. Normally a site survey is a need for distances over 500mtrs.
Wireless link for CCTV up to 5Km
Which CCTV Camera should I buy?
Apart from choosing the Mega pixels ( resulation/sharpness) you need to decide which camera housing you should buy.
"Hikvision IP camera Turret sytle
The most popular type of Hikvision IP camera case is the "Turret" style which is sometimes called an "eyeball style". This has a ball-and-socket type of design. It is like a sliced sphere, which can be easily swiveled around in its “socket” once the base has been mounted. The main reason its popular is that its easy to adjust the angle its pointing toward whichout affecting the image quality. Others cameras can suffer from Irnfra Red " fogging " if miss adjuested. The camera doesnt have to be opened to installed thus elimanting rain/mositure issues. The lens and infra red LEDs are in a seperate section whch minimises infra red light reflctions from rain and dirt.
Hikvision IP camera Bullet style.
Bullet style Hikvision IP cameras are a type video surveillance camera that is typically small and shaped like a rifle bullet shell or lipstick case. Bullet cameras can easily mount to ceilings or walls because most of them use a tri-axis type of mount. Not all bullet cameras are small. Infrared bullet cameras tend to be larger in diameter to accommodate the additional space that their IR LEDs require
