I'm looking for a good office camera security system. Any recommendations?

I would prefer the cameras to be wireless and to have a DVR. It would be nice if there was an app I could access the system from my phone. I would probably need at least 12 cameras.


Answer
I like Swann and Lorex systems for these (or smaller) systems.

There may be valu in getting two systems so if one fails, all the cameras are not down - but that is up to you.

Since we do not know the office layout, we do not know how the "wireless" part will work going through walls made of various materials.

Quick review:

Wired security cameras have a single "bundled" cable that contains the video feed and power. There are two plugs at the camera - one for power and one for video. At the DVR there is a connection for the video and the power plug connects to a power source - usually a "wall wart" or some sort. You can locate a battery back-up system at the DVR to power the DVR and the camera in the event of a power outage.

Wireless security cameras send only the video wirelessly. The camera still needs power (wire #1). If battery backup is needed, then some sort of local UPS is needed. The video is transmitted wirelessly to its base station mate. The base station needs power (wire #2). The base station connects with wire (#3) to the DVR.

You will also want to invest in a couple of monitors that connect to the DVR. 16 channels is a lot to watch. For the monitor at the DVR, a low priced, VGA-connected computer monitor is fine. There may be a need to have auxilliary monitors around the rest of the property. Use of the composite video out makes that easy.

Connecting the DVR to the computer network is easy enough - be sure the network is segmented using a network switch (not just a hub) so the video traffic and be isolated from the rest of the network. Use of PnP is easy, but a network admin with half a clue will know how to set the IP address and security properly. Also, for the remote access you want, setting up the router to allow your access while maintaining network security is needed. Again, any half skilled network admin who understands IP networks and router configuration can do this. This works best if your internet provider gives you a static IP address, but can still work if a dynamic address is used - there are some work-arounds and compromises you'll make is you go this route.

I would suggest sizing the system with more ports for cameras than you think you need - in case you decide to add cameras. In this case, two 8-channel systems gives you decent coverage. And a composite security camera will work on any manufacturer's system. I have installed Swann DVRs with Swann, Lorex and other manufacturer's analog, composite video, security cameras...

You did not tell us if the cameras will all be indoors or if there will be any out door (parking lot, alley, etc) in which case you may want outdoor-rated night-vision cameras in addition to the indoor versions.

business question "antique mall owner needing security camera system" which is the best to buy?

Just trying to get input from someone that has an antique mall of similar business. I want to purchase a camera system that I can set up in "EACH" booth or atleast every other booth. Some can be dummies but I would like for atleast half of them to be the real deal. I ahve heard of dealers using globes and dummy cameras to deter thieves; does this work?
What system would you recommend and please don't say a 10,000 one, I cant afford that at the moment.



Answer
Hello

Dummy cameras are the worst possible they don't provide security and if someone is injured or claims to be injured in your store they can sue for providing a false sense of security. No professional security installer uses dummy cameras.

Here is a DVR that will work perfectly for you.

I would recommend a Standalone DVR as they are more reliable and since they are linux based they are virus ans spy ware free.

The X4S Series DVR is an intelligent and professional CCTV management solution, integrating the latest technology and the most advanced features while maintaining a simple, intuitive, and graphical interface. The X4S Series DVR is a 24/7 turn key solution that meets demanding security needs to suit industrial and commercial applications. The X4S DVR is compatible with the X4 platform, allowing it to act as an IP server, while still remaining a standalone solution and allows you to view your cameras instantly over the internet with a PC or cell phone like the I-phone.

also here is some information on DVR and cameras you may want to read before buying a CCTV system.

Not all DVRs and security equipment are created equal, in fact there are many options that offer varying performance much like the automobile industry. In the world of DVRs you can find the equivalent of a $10,000 Kia and a $350,000 Ferrari and everything in between. Both have 4 wheels and windshield but that where the similarities end, itâs under the hood that counts. Just like any other consumer electronic in the end you get what you pay for.

I suggest you buy a PC based DVR has they have more processing power and normally have a much smaller file size and offer more features then Standalone DVR's. I know many people buy a cheap standalone DVR, only to upgrade to a PC based in 6 months especially when they are using it to manage a store remotely. Also PC based allows you to record up to 64 cameras where a standalone will have a limit of 16.

Many people have the misconception that a PC-Based DVR is simply an off-the-shelf PC with video capture (encoder) cards, display (decoder) cards and some generic OEM software. A true DVR requires years of research and development to facilitate the seamless integration of both the hardware and software. DVRs are highly complex systems that must run 24/7, processing millions of images per day. This makes consumer-level hardware inadequate for DVRs which is why Ascendent uses custom-built PCs with performance-level hardware.

My personal favorite DVR is Ascendent X4 series: Ascendentâs Tri-Fusion Hybrid Platform allows for the creation of a true hybrid surveillance system by utilizing the advantages of Analog, Megapixel, and IP technologies for unparalleled customization and expandability.

The X4 also uses the latest H.264/SVC codec offer video substantially better quality,. While its file size sizes is 30% smaller than MPEG-4, 60% smaller than MPEG-2, and exponentially smaller than MJPEG.

File size is crucial to streaming because most DVRâs on the market record at real time performance (30FPS per channel) so on a 4CH is trying to send 120, 8CH 240, and a 16CH 480 images per second which requires way too much bandwidth even for the most extreme internet connections.

The smaller the files size the more images are able to be sent, and the faster they can be processed improving both FPS and speed. File size is the heart of any DVR and goes far beyond just its streaming capabilities, as it also determines the recording storage time, how much you can back up at once, how fast it renders and searches video. The file size of a DVR impacts the performance of the DVR in just about every aspect from speed to longevity and is often the most important spec of any DVR.

If you are buying a DVR and streaming is a high priority I suggest you ask for a demo and connect to the DVR to make sure it is able to stream fast enough for your needs. Most DVRs say they have remote viewing but it is often too slow and laggy to be of any use especially if it is a standalone. Some good DVR brands that I recommend are Bosch, Pelco, Honeywell and Ascendent. These brands are what security professionals use.

I recommend Ascendent as they are less expensive because they cameras for companies like Bosch and Pelco and offer better performance but any of these 3 brands will work well.


These brand manufacturers also have a complete line of CCTV cameras and DVR for any application from residential to military and stand behind there warranties. You want to get a good bran name otherwise you will likely buy a product that work and cant be returned.
