Any DIY enthusiast will happily tell you that Hikvision and Dahua CCTV and IP cameras are the absolute best choice for the task. Both of these security camera brands are extremely popular in Singapore, with Hikvision probably being a more sought-after choice as of now. There is no particular reason for that phenomenon, although generally speaking, Hikvision is the slightly cheaper choice out of the two options. In any case, Hikvision is the world-leading IP camera manufacturer as of right now, and at the time of writing this (2017), it has a 17% market share. Dahua is the second one with a respectable market share of 5.5%. (Data source: IHS) For demonstration purposes, we will be comparing the latest 4MP IP cameras, Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS, because this resolution will likely become the golden standard for home CCTV cameras in the near future. 1. ONVIF and RTSP support for Hikvision and Dahua IP CamerasONVIF and RTSP are probably among some features you should look for in an IP camera, especially if you have existing NVR. Hikvision as well as Dahua security IP cameras both support them just fine. ONVIF is there to make sure the camera is compatible with equipment from third-party manufacturers, while RTSP allows software and other equipment to access your camera’s video stream. One example is the ever-popular VLC player. 2. The sensor used in the IP CamerasBoth Hikvision and Dahua IP cameras have a 1/3” Progressive Scan CMOS sensor, the most common one you can find in these type of IP cameras. When buying a security camera, the size of the sensor is quite important. It directly influences the low light ability of a camera, and this holds true for camcorders as well. Basically, larger sensors are better suited to operate in low light conditions. Here is how it works: by trying to cram more and more pixels into a sensor that has the same size, additional noise is created, which – in turn – reduces the details in the video. As you can see, a larger sensor effectively reduces the problem. In any case, both Hikvision as well as Dahua 4MP models have true 120dB Wide Dynamic Range (WDR). This serves to further improve the video quality. 3. Minimum illuminationMinimum illumination measures the minimum amount of light required for a CCTV camera to produce a viewable image. In this category, both IP cameras are the same: both are capable of 0.01 lux and 0 lux with IR on. 4. Lenses used in Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-ASBoth Hikvision and Dahua security cameras allow multiple fixed lenses with different focal lengths. Hikvision has 2.8mm, 4mm and 6mm, 8mm and 12mm lenses, while Dahua uses 2.8mm, 3.6mm, and 6mm. Hikvision offers a consumer a bit more options. 5. Max bitrate of the IP Cameras(Read here to know what is bitrate) Another difference between Hikvision vs Dahua security cameras is that Hikvision’s model has a max bitrate of 16Mbps, while the Dahua’s model has a max bitrate of 10 Mbps. However, that is a bit far from being a reason for concern. Both bitrates of up to 10 Mbps are usually more than enough for what you’re going to need. 6. Weight and dimensionsIn terms of weight, both cameras are nearly identical: they are both around 0.5 kg. As for the dimension, Hikvision is 4.4” × 3.2”, while Dahua is 4.33”×3.19”. Again, these differences are minimal and noticeable only if you put one camera next to another to compare them. In practical scenarios, the difference is probably not going to matter. 7. Price of the IP CamerasGenerally, Hikvision security IP cameras tend to be slightly cheaper for some reason. However, there are different ranges of IP cameras with different features coming with totally different price ranges. Therefore, we recommend that you make your decision based on the features each of these models provide, not price alone. 8. Resolution of the IP CamerasBoth Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-AS IP cameras have the resolution of 2688 x 1520 as the maximum. 9. Simultaneous video streamsHere is another difference between the brands: in this category, Dahua outperforms Hikvision, since Dahua allows for 3 simultaneous video streams at different resolutions, while Hikvision only allows for 2 streams. Note: this is only relevant if you’re trying to do multiple simultaneous streams at different resolutions. If the resolutions are going to be of the same quality, this will not affect you in any way. 10. Frame ratesTypically, you can expect the frame rate to jump anywhere between 20 and 30 fps. Dahua’s technical sheet promises for it to never fall below 25 fps, while Hikvision runs at 20fps with the resolution of 2688×1520, 25fps with the resolutions of 1920×1080 and 1280×720. In all of the other modes, however, the minimal fps you can expect to see is 25. 11. Motion detectionMotion detection is one of the most desirable features for a reason: it helps conserve storage space, as well as saves time when reviewing the recorded footage (since you probably only want to go over the parts when something moves unexpectedly). Long story short: both models support motion detection feature. Conclusion of comparison of Hikvision DS-2CD2142FWD-IWS and Dahua IPC-HDBW4431E-ASWhile there are subtle differences between Hikvision and Dahua security IP cameras, comparing them really comes down to personal preferences. You can’t go wrong with either one of them. Want to install the Hikvision and Dahua Security CCTV Cameras and IP Cameras? Contact us and you will get the best price in Singapore.

When buying a safe box, there are multiple considerations you need to make. This can be quite a challenging task, especially if you don’t know much about safe boxes in general. To make it a bit easier, we’ve compiled a comprehensive safe box buying guide that should answer the most common questions you might have: 1. Weight is one of the most important factors of safe boxWhen buying a safe box, the heavier it is, the better. A thick exterior means it’s less likely for the contents to get damaged in a fire, and heavy weight means a burglar will have a very tough time just ripping it from the wall and carrying it with him. Obviously, a thick exterior is also much harder to penetrate by force. If you can, try to get a concrete amalgamate-based composite fire safe and make sure it carries a lot of steel components. The fireboard, drywall-based fire safes, and any panel-based safe boxes can be a good budget-friendly option, but they provide a bit less safety in fire situations. 2. Look for a solid steel door of safe boxThe safe box door must be built to last. Essentially, it’s one of the most important parts of a safe box. The alternatives are mostly a compromise between budget-friendliness and safety. For the best possible protection, you should look for a solid steel door with a minimum thickness of ½”, and solid steel body with a minimum thickness of ¼”. You see, steel can be quite expensive. The more of it the safe box contains, the more expensive it is to produce and the shipping costs can quickly go up as well. This is the reason why many safe box manufacturers make compromises during the manufacturing process to cut down the costs, so they can offer an affordable product that is still reasonably safe. But in the end, it’s up to you to find the optimal balance between safety and affordability. 3. A good safe box should have a UL approved lockIn an ideal situation, go with a UL approved Group 2 quality lock; Sticking with a proven brand such as these will ensure that your lock will serve your for many years down the road without having to deal with an early failure. Beware of the no-name brands, however, since 95% of these are almost guaranteed to fail rather soon. If such a thing happens, even the most experienced locksmiths may have a hard time opening it without having to resort to forced entry, which does save your belongings, but renders the safe box unusable, leaving you with a hefty bill. So to keep it simple, if you see any of these brands, you can rest assured the safe uses a quality lock. Then again, quality locks aren’t limited to these brands either, it merely means these are the most likely to stand the test of time. 4. Does the safe box have relockers?Relockers are basically another safety measure against burglars. If your safe box ever finds itself under attack, these hardened pins are triggered, which means the burglars would have to resort to drilling in order to access the safe by force. However, that would take them hours upon hours of time, which is more than enough for the police to be alerted and is something they cannot afford. Depending on the size and burglary grade of the safe, you can expect to see anywhere from 2 to 10 of these in any particular model. Again, you should base your decision on what type of items you’re going to store in your safe box, and choose a model accordingly. Some items are probably not as valuable to fret over. 5. Convenience matters of a safe boxWhat is the safe box going to be used for? Can you make by with a smaller model, or will you need to store larger objects? There are all sorts of different models that come in different sizes and are made for different purposes, so you need to consider what you’re mostly going to be using it for. Aside from that, you should install it in a place where you can reset the lock combination yourself without the aid of a locksmith. Also, it should be in a location that will provide quick access the safe. Conclusion on safe box buying guideBy following our safe box buying guide, you should now have a pretty good idea on what to look out for, and we are confident you will make a great buying decision. Make sure you try our Safe Box Selector, which will help you to find the right safe box within 10 seconds.

As a free software based know-how, any video surveillance producer can develop HD-TVI devices. HD-TVI is a combination of high-resolution footage and fast analog data transmission. Modulation-demodulation process and image processing by means of an analog method are merged with the features of HD technology, resulting in a great and practical solution. One of the main characteristics of HD-TVI is the possibility to change a digital signal into an analog signal as well as taking up less storage space. Also, HD-TVI takes uncompressed High Definition video and makes the transmission over long distances via a coaxial cable. Hikvision HD-TVI Technology CCTV CameraAs one of the biggest video surveillance companies in the world, Hikvision offers HD-TVI options as analog solutions with high-quality performance.

This means that if you already have an analog CCTV video surveillance system, you can easily get to the next level to HD resolution with a minimum investment in wiring and related infrastructure. HD-TVI technology allows you to use the existing coaxial cables for transmitting a 720p or a 1080p HD resolution video, guaranteed for up to 800 meters (720p) and 1200 meters (1080p) with a high quality and reliability, a distance that would be really hard to achieve by a regular analog technology. In addition, this solution is compatible with IP cameras and other HD-TVI devices, being an open standard. Thanks to this feature, Hikvision’s HD-TVI devices can work with no trouble when connecting them to HD-TVI compatible DVRs or cameras from a different brand. HD-TVI technology by Hikvision also offers the possibility of remote configuration via coaxial cable, so it is a fact that the user can make changes and set up the system without having to be where the camera is, making it easier to manage the whole camera installation. Why Should You Consider HD-TVI Camera by Hikvision?There are many advantages that make Hikvision’s HD-TVI CCTV camera range a very appropriate solution:
HD-TVI technology by Hikvision is always improving. Each solution provides high-resolution devices (up to 5 MP and 4K video output) and the constant research and development keeps bringing even more efficient products and installations that bring you the possibility of having a high definition camera system without the need of replacing any of the cabling previously installed for analog devices or making expensive substitutions with IP cameras.

HD-SDI cameras are the High Definition alternative among analog surveillance equipment. They are capable of delivering resolutions of 720p and 1080p. Some models are built as vandal-proof, offering color or black/white footage, and also come in several shapes (dome, box, bullet) as well as tow lens options (fixed and varifocal). However, it is worth the attention that HD-TVI turbo CCTV cameras occupy the main lines of Hikvision’s daily analog cameras’ production. Large Variety of Network IP Cameras from HikvisionNetwork IP cameras offered by Hikvision are superior in terms of resolution and the range of features that can be achieved with it. This technology, being based on a network installation supported by the internet, allows even more functionalities than analog cameras such as:

What are the pros and cons of wired and wireless CCTV cameras? As you might have guessed, none of the options available are perfect, so it mostly comes down to your personal preferences. But to make your buying decision easier, we’ve composed a comprehensive list of what you can expect from each type of device, both positives, and negatives. Note that a wireless CCTV camera has to be a digital IP Camera, as only digital signal can be transmitted wirelessly. General Comparison of Wired and Wireless CCTV Camera in Table
Advantages of Wireless CCTV Camera1. Easier installationThis is especially important if you want to do it yourself. That way, you will save time and also ensure that you’re going to be capable of doing it in the first place. In a typical scenario, all you have to worry about in terms of installation is having a power source in close proximity to your wireless CCTV camera, and you’re good to go. 2. PortabilitySince these types of wireless CCTV cameras tend to be rather lightweight and easily installed, you can take them anywhere you want to without trouble. 3. Can be placed anywhere there is a Wi-Fi signalExtending on the previous points, as long as you have a power source and a Wi-Fi signal nearby, your wireless CCTV camera will serve you well. This also comes in handy if you want to move it to another location later on. 4. Reduced maintenanceMaintaining a CCTV camera can be troublesome. But since a wireless CCTV camera doesn’t need a cable to function, ideally you won’t be spending any money on cable maintenance (although you will still need the power cable to power up the wireless CCTV camera) Disadvantages of Wireless CCTV Camera1. Less reliable than wired CCTV camerasThe reliability of wireless CCTV camera relies on the wi-fi signal. Sometimes you’re going to be experiencing instability of wi-fi signal, or even weak signal, which means you could potentially lose some crucial moments of footage. In that aspect, a wired CCTV camera is more reliable than a wireless CCTV camera 2. Risk of being hackedData security is an important aspect of today’s world, and the con of using a wireless CCTV camera is that you risk being hacked. Although breaching the security of your camera is not something that a novice hacker can do seamlessly, there is still a risk. Knowing this, you have to make a decision based on how comfortable you are that someone else may have access to the recorded footage at any given time. 3. Cost is highFor the most part, wireless CCTV cameras tend to be more expensive than their wired counterparts. 4. Possibility of interferenceSometimes, wireless CCTV cameras experience interference which can lead to false alarms, dropped signals, and lost video. Benefits of Wired CCTV Camera1. Best video qualityOut of all the CCTV cameras, wired CCTV cameras tend to have the best picture quality. 2. No interferenceIf you’ve installed a wired CCTV camera properly, one of the pros is that you won’t have to worry about any interference from Bluetooth devices, telephones, wireless networks, alarms, microwave ovens, baby monitors, and the like. 3. ReliabilityExpanding on the previous points made, a wired CCTV camera is one of the most sturdy and reliable options if you’re looking for the best picture quality and availability at all times. 4. No need for a power source nearbyUnlike with what you can expect from wireless CCTV cameras, a wired CCTV camera doesn’t require a power source nearby – a cable will carry the power to it. And if you use a power distribution box, many cameras can be powered at once. Disadvantages of wired CCTV camera1. Installation can be challengingUnlike wireless CCTV cameras, a wired CCTV camera can be quite challenging to install. Unavoidably, you’re going to have to drill a hole in the wall, and you can run into all sorts of obstacles while you’re at it: concrete blocks, studs, and the list goes on. To make matters even trickier, these are hidden behind the wall, so you won’t be able to tell them in advance. And if you want to steer clear of interference in picture quality, you’re going to have to avoid placing the cable along a high-powered line. 2. Not easily portableAs you may have imagined, since there is a lot of work involved during the installation phase, moving it to a different location can be quite tricky, and it’s usually better to just get a new one in this case. ConclusionWhen considering the pros and cons of wired and wireless CCTV cameras, you always have to consider what matters the most to you, as well as the budget you have available. But hopefully, this article has helped clear up some of the questions you may have had.

How does a CCTV camera work? You may be asking yourself this question before installing the CCTV camera. To start, CCTV stands for Closed Circuit Television and it’s a system used for video surveillance which combines a certain number of cameras linked to each other that are placed in the desired zone in order to keep track of actions taken there. It is called “closed” because their footage is not broadcast to the public; it is used exclusively for safety and security purposes. Real-time live viewing is one of the main reasons why people install CCTV camera systems in their homes, offices, retail shops, warehouses, schools, restaurants, etc. These systems allow them to keep their families and assets safe and well watched. The working logic of a CCTV camera should be known by everyone that feels the need of installing a CCTV Camera surveillance system, whether at home or in their business. Here is an explanation of how these devices work, beginning with some essential definitions. 1. Basic Characteristics of CCTV CameraA CCTV camera is an equipment composed of an image capture element (CCD or CMOS, explained below), an electronic circuit and a lens that will allow the visualization of a specific scene. Some CCTV cameras also include microphones that allow to catch the sounds of the environment under surveillance and send them through the network for listening and recording. There are different types of cameras, one for each particular usage. Depending on the conditions of the area that needs the coverage, specifications and characteristics vary. For instance: black and white/color image, outdoor or indoor use, housing, sensibility to light, resolution, size, etc. Different types of lenses can also be found in the cameras and they can be chosen according to the requirements of every installation. Zooming options can be offered as well as other image adjustments that contribute to a better and more precise footage. 2. Analog and IP based CCTV CameraCCTV camera can be further classified into two main types: Analog and IP Camera. These two categories are associated with the way the image is compressed and transmitted towards the video recorders. Analog cameras are connected to each other using a coaxial cable and further connected to a monitor or TV where footage can be seen and recorded with a specific device. IP camera can be connected with each other wirelessly (Wi-Fi) or via an Ethernet cable. Footage can be recorded inside the Network Video Recorder (NVR) or watched in real time from a PC or smartphone using the Internet. This kind of cameras offer higher resolution levels and consequently, a better image quality. 3. CCD and CMOS sensors of CCTV CamerasBoth types either have CCD (Charge Coupled Device) sensors or CMOS (Complementary Metallic Oxide Semiconductor) sensors. In any case, their function is to convert light into an electrical signal that is later processed and converted into a signal output that can be both recorded and shown on a monitor. Most analog cameras use CCD chips while IP camera can use CCD or CMOS sensors indistinctly. The main difference between them is that a CMOS may not deliver a footage with good resolution when there is movement in the scene while CCD is able to offer sharper images in the video. However, CMOS technology has improved and it is possible to get a high performance at a lower price, compared to CCD chips. 4. Image Compression: DVR and NVR of CCTV CamerasThe analog signal (in analog CCTV camera) is turned into a digital signal thanks to a converter (analogue-digital) and then it is transmitted to a DSP (Digital Signal Processing). Then this digital signal is turned again into an analog one via another converter so that it can be transmitted to the Digital Video Recorder (DVR) where it is codified and stored. In the case of IP camera, the image is internally compressed or codified and transmitted through Internet Protocols (IP) using a network until it reaches the recorders, which are called Network Video Recorders or NVR. 5. Usage of CCTV CameraInfra-red cameras are preferred for night surveillance. They use Light-Emitting Diodes (LED) placed around their lenses so they can detect heat waves and retransmit the images into the black and white footage. There are also adaptable cameras that automatically change their working mode according to the light conditions of the place. Dome-shaped cameras, spy cameras, and other types are available for every particular condition. CCTV cameras are the essential part of video surveillance systems and their different characteristics must be taken into account in order to make the right choice for the whole installation and make the most out of their technology.
