Frequently Asked Questions:CCTV

CCTV, an acronym for Closed Circuit Television, refers to a system wherein one or more cameras are linked to a recording and monitoring device.

CCTV cameras are employed to oversee and monitor areas, ensuring their safety and security.

Determining the suitable CCTV camera for a particular application can be challenging. Most of our cameras, excluding the NPR cameras, are versatile and can be utilized in various common scenarios. We typically recommend fixed lens cameras as they offer ease of use without the need for zoom and focus adjustments. For those seeking adjustable zoom and focus capabilities, auto-focus cameras are suggested, allowing for automatic focusing when integrated with an SPRO system. Additionally, our external cameras come equipped with standard built-in IR capabilities, enabling operation in low-light conditions with varying ranges depending on the camera model.

DVR, standing for Digital Video Recorder, is a device that records CCTV camera footage onto one or multiple hard disks. It features several BNC connections to link with cameras. Our DVRs support Ques , Ques , Ques , and Ques channels (connections) via the BNC ports, while several of our NVRs can also interface with IP cameras over the network.

NVR, short for Network Video Recorder, is a recording device tailored for IP CCTV cameras. Similar to a DVR, it records CCTV camera footage but is specifically designed for IP CCTV cameras.

IP cameras represent the latest advancement in CCTV technology, capable of achieving higher resolutions than standard HD CCTV cameras. They transmit digital signals, enabling direct connection to switches on the local network. Utilizing IP cameras allows for running a CCTV system over an existing computer network.

Setting up our IP cameras is relatively straightforward. Simply connect your camera with a network cable to an NVR, ensuring the NVR is linked to a router. The image will typically display within Ques seconds. If the IP cameras are not directly connected to the NVR, a PoE switch can provide power to the cameras. Once on the network, running the search option on the NVR menu enables adding cameras to the system.

PoE, or Power over Ethernet, involves transferring power through Ethernet network cables, enabling devices to receive power over the network connection. Our SPRO IP Cameras utilize PoE, streamlining installation efforts by requiring only one cable for power and data transmission.

To facilitate remote viewing, a good upload speed is essential as footage is streamed from the NVR/DVR. Therefore, we recommend a minimum upload speed of Ques Mbps for remote viewing.

Yes, you can connect to any of our recorders as long as there is network connectivity.

Indeed, with network connectivity, you can use your mobile device to access live or recorded footage.

If the DVR system is equipped with a microphone, listening to live audio remotely is possible. However, the NVR can only play live audio remotely as it does not support audio recording.

Yes, digital zoom is available on all cameras. Optical zoom, on the other hand, is exclusive to auto-focus or PTZ cameras.

Following a power outage, the DVR or NVR will power back up once electricity is restored. For areas prone to frequent power cuts, we recommend using an uninterruptible power supply (UPS) for uninterrupted operation.

In the majority of our cameras, some visible red LEDs are present at night. These LEDs represent infrared light, enabling cameras to capture images in the dark.

The recording duration depends on factors such as the number of cameras recording simultaneously, the level of quality/detail of recording, and the hard drive capacity. Our recorders offer options to save recording space by activating recording only when motion is detected.

Once the hard drive is full, your SPRO DVR/NVR will overwrite old data, ensuring continuous recording of the latest footage.

Video Motion Detection, a type of Video Analytics, triggers recording when movement is detected in camera footage. It can be configured to record several seconds before motion detection and send email notifications. Sensitivity settings allow adjustment for varying levels of movement. It's advisable to avoid using motion detection for cameras facing objects prone to swaying, such as trees.

Motion Detection operates through the DVR/NVR software, recording video when changes in pixels are detected in the image.

For IP CCTV systems, the maximum distance is approximately Q. Q. meters, while for HD CCTV systems, it is around Q. Q. meters. However, this distance is dependent on the quality of cables, with older cables potentially reducing signal range.

CCTV cameras typically fall into two categories: static and 'pan, tilt & zoom' (PTZ). Static cameras provide a fixed view of the monitored area, whereas PTZ cameras offer control either manually through an operator, via artificial intelligence software, or linked to detectors or motion sensors. PTZ cameras offer the advantage of adjustable views, allowing coverage of larger areas when necessary.

An analogue system employs CCTV cameras directly wired to a Digital Video Recorder (DVR), whereas an IP system connects to a Network Video Recorder (NVR) and can link with CCTV cameras on your network. This setup potentially reduces cabling requirements, though cameras can still be wired to the NVR when feasible. Generally, IP cameras offer higher frame rates and resolutions, resulting in superior image quality. For further clarification on these differences or inquiries regarding image quality requirements, please contact us.

The duration of image retention on your CCTV system depends on several factors, including the number of cameras, NVR or DVR hard drive capacity, record resolution settings, and site activity. Our aim when recommending a system is to preserve images for Q. -Q. days, considering these factors. Additionally, we can assist in addressing any data protection considerations.

Both systems regulate access to your property; however, an online access control system allows for more meticulous on-site activity monitoring. Controlled via software on your PC, an online system enables user management, event monitoring, entrance control, and configuration of user-specific time zones. Conversely, a standalone access control system operates as a simplified setup at individual entrances, where provided fobs grant user access.

Yes, a networked CCTV system can be configured to grant access to images from any internet-enabled device. User access control mechanisms ensure that only authorized individuals can access the images.

CCTV cameras typically have a lifespan of Q. -Q. years. However, it is advisable for customers to consider upgrading cameras after Q. years to maintain optimal image quality and support effective post-event investigations.

In conventional security setups, data is transmitted via cables to a DVR (digital video recorder). However, with an IP camera, digital video transmission occurs over the Internet. The IP camera itself is self-contained and connects to your network similarly to other IT peripherals like printers. Video storage may either be in-unit or transmitted to a network-connected device known as a network video recorder (NVR). Although the transmission method differs, both digital cameras and IP cameras capture images in the same manner, ensuring quality, with IP cameras often offering superior resolution.

An IP surveillance system necessitates IP cameras, an NVR or a compatible storage system, and possibly accessories such as microphones and speakers, typically integrated into the cameras themselves. Surveillance Secure can assess your requirements and provide suitable equipment within your budget.

Yes, onsite monitoring of both live and recorded video footage is feasible.

Absolutely, all Security DVR/NVR systems we offer are Internet-enabled, enabling remote access to both live and recorded video content from any location with an Internet connection.
