CCTV is an acronym for Closed Circuit Television. They are the modern day solution for your security needs. If you are going away from home and you looking for someone for surveillance, there is no need to hire a security guard, just install CCTV cameras to monitor your home, workplace, shops or office. CCTV cameras can even be installed in schools, railway stations, hospitals, banks, airports, police stations and colleges to have constant surveillance in the area. CCTV cameras can be bought online or in local stores but installing them does not guarantee outright safety of a premise, here are 6 Questions to Ask before You Installing CCTV Cameras:
1. How much do security cameras cost?
The cost of CCTV cameras vary depending on certain aspect such as the specifications, brand among others. The price of Fixed indoor security starts from $60 and they can cost as high as $200 while the cost of fixed outdoor CCTV cameras ranges from $100 to $300. PYZ security cameras are more expensive ranging from $400 to as high as thousands of dollars depending on the specifications you choose.
However, the cost of CCTV cameras is not all that you should be concerned with, there are certainly cheaper security camera systems but you will always get what you are willing to pay for. The cheaper options provide blurred images and they easily break down posing risk to your valuables.
When buying CCTV cameras, have a set budget but be ready to adjust if you get cameras that provide you better security with little or no maintenance.
2. Are wireless cameras a good option?
Wireless security cameras are mostly made for use in line of light and the outdoors. This means that the receiver antenna and transmitter antenna should be located away from any structures and they should be able to physically see each other. The signal of wireless cameras becomes week when it is obstructed by trees and walls causing a problem. Therefore, if there are objects in the area of surveillance, you will get unstable reception or no picture at all.
Cell towers and power lines can also kill the pictures as well as pumps and motors in the vicinity. Not to mention anything with the same or close frequency band as the cameras transmission such as cordless phones, cell phones, microwaves and vacuums. The wireless equipment also have to be hand wired to the power, therefore, the only thing that is wireless is the video. For better quality videos, you should choose the hard wired connection.
3. Where is the best place to install CCTV cameras?
Security cameras should be installed in strategic locations where they can easily record everything going on. The best place to install CCTV cameras are:
· Front door
This is the first place that you should consider installing security cameras. It can either be installed on the outside facing the front door or inside the house facing the front door. If the camera will be installed outdoor, purchase one that is weather proof with night vision capabilities. You also need an extension cord that connects to an indoor or outdoor power source.
· First floor windows
First floor windows are common entry point by burglars. The camera should be installed directly opposite the window on a high position to be able to get a clear image of the burglar.
· The back door
The back door is also vulnerable if the front do is open to the street. Install a security camera in the house facing the back door.
· The garage
Garages offers access to some of the most expensive items such as cars and bikes. Therefore, have a security camera installed facing the garage door in an angle that it is able to pick the face of the intruder even during day time.
· Side gate and Backyard
Backyards are easy to access the property from or even escape from. In homes, this is the area kids spend most of their time hence the need to keep it under surveillance. A single camera can capture the area, but you may need multiple cameras if the backyard occupies a big area. The best location to install the camera is the entry point to the backyard.
4. Should you need varifocal or lenses on the surveillance cameras?
This highly depends on your preference as well as the location of the security camera. Some of the security cameras with lenses give a very sharp picture but you cannot be able to adjust how the camera focuses. You can point the camera in a different direction but you can only be able to get what you see through the camera. Cameras such as Low Pro ceiling mount and Sentry-700 Dome Camera have a wide range of adjustments and they also have verifocal lenses that enable a user to adjust the zoom and focus manually enabling you to get the view you want.
You can easily move it with the hand to aim a different area and also change how far and wide you are able to see. This is important especially if you want to view a wide area.
5. Is there a need for battery backup for security camera systems?
A battery back up is important if you want to have uninterrupted surveillance of your premises. The battery backup should have two outlets to allow you plug in both the camera power supply and the DVR. In case of a power outage, the security camera is able to take the images while the DVR will be recording.
Go for a battery backup with a high VA rating so that it can stay powered for a longer period. Also, ensure you get a UPS that can be set automatically. This means when power goes out for a long time and exhausts all the battery power, the UPS is able to turn back on as soon as power is restored.
Some UPS have a non powered battery outlet but they give surge protection. This is very handy as it helps to keep your security monitored while plugged into a surge protected outlet without draining the battery in case power goes out.
6. Do you need infrared CCTV cameras?
If the camera is indoors, it depends on whether the lights stay on all night or not. Infrared CCTV cameras is great for outdoor security cameras.
