CCTV is a crucial expenditure when it comes to the security of your home or business. These surveillance cameras can deter or prevent criminals from entering your property and assist police in catching the perpetrators. There are a few different types of CCTV systems that we’ll go through and that is available and on display at our Alectra store.
Analog has been around for a long time and has proven to be a reliable security measure. When it comes to cost, Analog CCTV systems are also your more affordable option.
Analog cameras require separate cabling to control various functions and can send video over twisted-pair or coax cable to VCR or DVR. Wireless connections are also available but produce lower resolution.
Analog cameras perform well in low light and resolutions range from 420 to 700 which can process sharp images in the higher end
IP systems all use digital cameras and can be run over twisted-pair Ethernet cable to avoid installing electrical wire. IP CCTV can also be set up wirelessly where it is too difficult to run cable. All signals are encrypted and compressed before being transported and stored on your network.
IP cameras offer much higher resolution (6 to 20 times) than Analog that range from 1.3 to 5 megapixels and this will allow for a wider viewing area and more detailed images even when zooming in.
All the advantages of IP CCTV systems come a higher price than Analog but do keep in mind that less cabling is required and that could bring down your cost. We have IP cameras on display in our store but do not stock them on site so you’ll have to place an order for the system you would like.
PTZ cameras allow you to pan, tilt and zoom your video feed via DVR analog, NVR IP or via your cellphone if your cameras are connected to a router. We have these routers available but you will need to ensure that you have a sim card to be able to use the router.
