If it is intended, on your part, to make use of the unmarked vans then you should inform us about that and we’ll try to accommodate your request to the best of our control.
At your workplace, we’ll first plan your cable routing. It can take around 15 to 20 minutes. We’d also like to have you with us, if possible, for taking your approval on the route we have chosen.
It is always on our top priority to hide the cables as much as possible and ensure that job is done in the tidiest of manners; as a matter of fact, it makes us proud.
We typically install 4-6 camera systems inside a single day.
In case if your system is being networked, access will be required to some computer along with the passwords for the router. We do not save any of these details at all.
We keep dust sheets with us and remove any outdoor clothing or shoes before we step into your business place.

In case of credit card payments, a surcharge amounting up to 3.5 percent may apply; these options will be discussed by the installer.
14. What is the time duration for which my system will record?
Briefly, it would record until you want it to. It records all the data to an inbuilt hard disk drive. How long the images will keep on saving on the hard disk is directly related to the size of the disk. To give you a precise idea, 1TB hard disk drive can be enough to record 4 cameras for a month (depending on the frame rates). So, one camera will be recorded for more than 4 weeks.
15. What happens after it is fully occupied?
The old images are overridden by the DVR when hard drive does not have any further space left. For instance, if the capacity is to store recordings till day 30 then for storing recordings of day 31, it deletes recordings from day 1 in order to free up some space for new recordings.
16. Is it possible for it to record for a longer period?
Yes, if you switch it to the motion detection settings, the DVR will only record when the system detects some motion.
When used is normal situations, you can add weeks in storage time by using the motion detection setting, however it comes with a price. The sensitivity of motion detection needs to be really high for ensuring that nothing is missed. So, when you increase the sensitivity, it is likely to record wind and rain, particularly when the cameras are pointed towards something which moves in wind.
17. What do you do if someone is caught by me on Camera?
It is possible for you to be willing to provide that evidence to the Police. You can save the footage to the memory stick which can then be transferred to a CD/DVD and you can hand it over to Police.

18. Is there any light up feature incorporated in cameras for nights?
If you have infrared in your camera, then yes. Light, which is invisible for humans, is casted by little row of the infrared lights. In its absence, it may not be possible for the camera to see at night.
19. Can you provide cameras which can see when it gets dark?
Yes, we can! Our cameras are equipped with the infrared capabilities and, based on the budget you have, you can purchase cameras which offer better quality during the nights or in the dark and can see further distance.
20. How CIF Recording is different from D1?
Resolution refers to size of image being displayed. Most commonly used resolutions are CIF and 4CIF or D1. Almost all the DVRs use 4CIF or D1, however, CIF tends to be more famous resolution for recording. 4CIF and D1 have bigger images, and it takes more space on the hard drive to record these bigger images. Furthermore, frame rate of most of the DVRs needs lowering down so that these resolutions can work. The DVR whose frame rate is 30 frames/sec in the CIF mode may be able to record only 7 frames/sec in the 4CIF or D1 modes. DVRs rarely record at a rate of 30 frames/sec in the 4CIF or D1 modes, nearest possible is 25 frames/sec. One can easily afford DVRs. Most of the DVRs that we have can record at 25FPS in the D1 resolution and are quite affordable.
21. What is meant by TVL?
The video resolution for ‘Analog CCTV surveillance can be measured in terms of TV lines that can be viewed on monitor screen. One can measure video quality with the help of converging lines that are higher in density. Resolution number of the TVL is its line density at a point where camera can’t reproduce any individual lines any longer. The picture keeps on getting better as the number increases.
22. How 420 TVL is different from 700 TVL?
If you have seen CCTV monitors, you might have noticed that mostly the videos or images captured by them are blurred, and distorted and you can’t even be able to easily distinguish someone’s face; the reason for this is that you’re looking at the 420 TVL cameras that are low quality. The basic difference between 420 and the 700 TVL cameras is their resolution. Obviously, the 700 TVL CCTV cameras can be the far better option than their low cost counterparts. The cameras that are normally seen in some of the convenience stores, fast food chains or some other properties are the 420 TVL cameras. Even though they are regarded as an excellent way of staying protected at low cost while keeping an eye at the individuals that may have any bad intentions, having all the technology advancements in the industry at the moment at our disposal, why one should go for something less when they can have better and improved solutions? So, when you choose 700 TVL cameras you can enjoy better resolution and this, in turn, means that you will have more security through better quality images that you can be able to see through that camera; it is just like comparing security guard having 10/10 vision with the one having poor vision.
